--- title: "Company data API: firmographics, funding and hiring" description: "Every company data API in the directory, compared on the firmographics, funding, tech stack and hiring signals each returns, and what each one costs to call." url: https://frontal.so/gtm-apis/company-data-apis updated: 2026-11-12 --- By data · Company data APIs # Company data API: *the company record, field by field* Eighteen providers in this directory return a company record by API. Some sell firmographics, some sell what just changed about a company, and a few sell both. Short answer For funding history, Crunchbase, though only on a quote; for hiring as the signal, TheirStack, priced per company from $49. Apollo or [People Data Labs](https://frontal.so/gtm-apis/enrichment-apis/people-data-labs-api-review) when you want the company record alongside the people on it.

It is the record an account list, a scoring model or a territory plan is built on. Most of the providers on this page sell company data next to person data, because the two are joined in every outbound workflow. The person half of the same providers is on [people data APIs](https://frontal.so/gtm-apis/people-data-apis). This page is about the company row: what fields it carries, how fresh they are and what each provider charges to return one. The list is chosen from the records rather than by hand. A provider is here because its record says it returns firmographics and its primary job is sourcing, enrichment or signals. Search and scraping APIs return pages about companies rather than a company record, so they are on their own pages. The fields ## Firmographics, funding, tech stack and hiring are four different datasets Firmographics are the base layer every provider here carries: who the company is, how big, where and in what industry. The useful differences start one layer up, where a provider either has a specialist dataset or does not. [Crunchbase](https://frontal.so/gtm-apis/signal-apis/crunchbase-api-review) is the company dataset most GTM teams reach for first for funding. Its API serves the data behind the site: funding rounds, investors, acquisitions, headcount, locations and company history. Like [Cognism](https://frontal.so/gtm-apis/enrichment-apis/cognism-api-review), it publishes no rate card at all. - **Funding and corporate events**: Crunchbase, for rounds, investors and acquisitions. [ZoomInfo](https://frontal.so/gtm-apis/enrichment-apis/zoominfo-api-review) also returns real-world business events as part of its intent data. - **Technographics**: TheirStack reads the technologies a company runs from its job postings, and Apollo, Clay, Findymail, Cognism, Lusha, ZoomInfo, [RocketReach](https://frontal.so/gtm-apis/enrichment-apis/rocketreach-api-review), Clearbit through HubSpot and [Crustdata](https://frontal.so/gtm-apis/enrichment-apis/crustdata-api-review) carry tech stack fields too. The full comparison is on [technographic data APIs](https://frontal.so/gtm-apis/technographic-data-apis). - **Hiring**: [TheirStack](https://frontal.so/gtm-apis/signal-apis/theirstack-api-review) sells every job posting a company has published as rows, and Apollo, Clay, [LeadMagic](https://frontal.so/gtm-apis/enrichment-apis/leadmagic-api-review), Crustdata, Cognism and Crunchbase carry job data as well. - **Registry identifiers**: [Dropcontact](https://frontal.so/gtm-apis/enrichment-apis/dropcontact-api-review) returns French registry fields, SIREN, NAF code and VAT number, alongside the address and the company leader. - **Domain-led firmographics**: [Hunter](https://frontal.so/gtm-apis/enrichment-apis/hunter-api-review)'s Company Enrichment returns firmographics for a domain, and its Domain Search returns every address a company publishes. Pick the dataset your scoring actually reads. A model that weighs hiring and stack needs TheirStack or Crustdata whatever the base firmographics cost. What changed ## A company record ages, and a signal is what tells you it changed Headcount and industry change slowly. What a sales team usually needs is the change itself: a funding round, a burst of hiring, a new tool in the stack. That is the line between a company data API and a [buying signal API](https://frontal.so/gtm-apis/signal-apis), and several providers sit on both sides of it. Job postings are the cheapest honest signal in B2B, because a company hiring for a role has already decided to spend. TheirStack prices that as rows: through the API a job costs one credit and a company three, and its entry subscription is $49 a month for 1,500 API credits. Crunchbase answers the other question most databases cannot, which is what just changed about this company in its funding and ownership. Two hundred calls a minute, with 3 in flight at once per key, is generous for a signal workflow, where you look up the handful of companies that did something this week, and tight for a backfill of the whole market. The practical split is to load firmographics once, from the cheapest broad provider, and to call the signal providers only for the accounts that moved. Public company data ## What a public company data API can and cannot mean here The phrase public company data API is searched two ways. Some people want data about publicly listed companies, the filings and financial statements a regulator publishes. Others want public data about any company, the facts that are on the open web rather than inside a private database. This directory carries no filings API. None of the providers on this page sells SEC filings or audited financials, and inventing one to fill the gap would be the opposite of the point, so the honest answer for listed-company financials is the regulator's own data rather than a GTM vendor. For public data about private companies, the closest fits are Crunchbase for funding and corporate history, TheirStack for the hiring and stack a company publishes in its own job ads, and Dropcontact for French registry identifiers. Each one is a dataset with its own license rather than a free public source. Read the license either way. Crunchbase's terms forbid passing its data to a third party unless your own license says so, and require a link back to the company on Crunchbase when content is about one company. LinkedIn company pages ## LinkedIn company data, and the API LinkedIn does not sell for it A lot of company data API searches are really LinkedIn company data API searches: people want the company page, its headcount and its employees as data. What LinkedIn's own API grants, and to whom, is on the [LinkedIn API page](https://frontal.so/gtm-apis/linkedin-api), and it is worth reading before assuming LinkedIn sells its company data by API. The providers here take their own routes to company profiles. Reverse Contact fetches profiles from a social URL and is unlimited for those fetches on its $249 Go plan. PhantomBuster runs prebuilt automations through your own LinkedIn account and bills execution hours rather than requests. Crustdata returns a company profile from a domain, a URL, a name or an identifier, from its own index or from live endpoints. Its company enrich default is 15 requests a minute, low for single calls and the reason its batch endpoints exist. Whichever route you take, the account that does the fetching and the terms it runs under are part of the decision, not a footnote to it. Matching ## How a company is matched, and why the key decides the result Every company data API has to decide which company you meant before it returns anything, and the input you send decides how often it guesses wrong. A domain is close to unambiguous. A company name is not: two firms share most names, and a parent and its subsidiaries often share one website. The providers here are built around different keys. Hunter starts from a domain and returns its firmographics alongside every address the domain publishes. Dropcontact requires a company or a website on every contact and errors without one, because it has no database to fall back on. Crustdata accepts a domain, a URL, a name or its own identifier. Crunchbase solves the name problem with a purpose-built autocomplete endpoint that turns a messy company name into a Crunchbase identifier, and a deleted entities endpoint that tells you what it has removed since your last sync. That second one matters more than it sounds for anybody mirroring the dataset. The search for LinkedIn API company data is often the same matching problem in disguise: a LinkedIn company URL is a clean key, if the provider you call can resolve it. Check which inputs a provider documents before you assume your CRM's company field will match. Normalize to a domain wherever you can, keep the provider's own identifier once you have it, and most matching errors disappear before they reach a bill. What a company costs ## How company data APIs bill for a company record Company records are priced on a different meter from contacts on most of these providers, and the cheapest company lookup is often free search rather than a paid enrichment call. LeadMagic runs company search free in the app on every plan, and on the API at 1 credit a returned result on Essential and Growth and nothing from Professional upward, with Company Enrichment drawing on the same balance as everything else. ZoomInfo charges nothing to search companies or find similar ones, and one data credit, $0.38 at its $1,000 tier, to enrich a company. Wiza meters company enrichment by rate rather than by a special price, 30 a minute and 43,200 a day. Clearbit's company data is now HubSpot data enrichment, available only inside HubSpot on paid Starter seats and above, and HubSpot says it uses no HubSpot Credits, so its price is the seat rather than a meter. Three providers publish no dollar price for a company. Crunchbase withdrew its free Basic tier, so existing Basic keys still work and new ones are not issued, and access now starts with a quote through sales. Crustdata prices every record in credits and does not publish what a credit costs. Cognism publishes no price either, and meters its company filter in search tokens per row returned, which is a separate budget from the credits that reveal contacts. Price the company half of a workflow separately from the person half, because on most of these providers it is a different line on the same bill. Side by side ## The company fields, and what one lookup costs Returns lists the company datasets each record carries. Unit cost is the vendor's own published rate, and the unit changes from row to row: a credit, a record, an API credit, an export. | Provider | Returns | Entry price | Unit cost | MCP server | | --- | --- | --- | --- | --- | | [Apollo API](https://frontal.so/gtm-apis/enrichment-apis/apollo-api-review) | Firmographics, Technographics, Job postings, Intent and news | $49/seat/mo | $0.0196 per credit | Yes | | [Clay](https://frontal.so/gtm-apis/enrichment-apis/clay-api-review) | Firmographics, Technographics, Job postings, Intent and news | $167/mo annual | $0.0452 per data credit | Yes | | [People Data Labs](https://frontal.so/gtm-apis/enrichment-apis/people-data-labs-api-review) | Firmographics | $98/mo | $0.28 per record | No | | [LeadMagic](https://frontal.so/gtm-apis/enrichment-apis/leadmagic-api-review) | Firmographics, Job postings | $99/mo | $0.0198 per credit | Yes | | [Findymail](https://frontal.so/gtm-apis/enrichment-apis/findymail-api-review) | Firmographics, Technographics | $99/mo | $0.0198 per credit | Yes | | [Hunter](https://frontal.so/gtm-apis/enrichment-apis/hunter-api-review) | Firmographics | $49/mo | $0.0245 per credit | Yes | | [TheirStack](https://frontal.so/gtm-apis/signal-apis/theirstack-api-review) | Job postings, Technographics, Firmographics, Intent and news | $49/mo | $0.0327 per API credit, entry plan | Yes | | [Crunchbase](https://frontal.so/gtm-apis/signal-apis/crunchbase-api-review) | Firmographics, Intent and news, Job postings | Quote only | Not sold by the unit | Yes | | [Cognism](https://frontal.so/gtm-apis/enrichment-apis/cognism-api-review) | Firmographics, Technographics, Intent and news, Job postings | Quote only | Not sold by the unit | Yes | | [Lusha](https://frontal.so/gtm-apis/enrichment-apis/lusha-api-review) | Firmographics, Technographics, Intent and news | $37.45/mo annual | $0.087 per credit | Yes | | [ZoomInfo](https://frontal.so/gtm-apis/enrichment-apis/zoominfo-api-review) | Firmographics, Technographics, Intent and news | $0.38/data credit | $0.38 per data credit | Yes | | [RocketReach](https://frontal.so/gtm-apis/enrichment-apis/rocketreach-api-review) | Firmographics, Technographics, Intent and news | $33/mo annual | $0.25 per export on Pro, the first plan with phones | Yes | | [Clearbit](https://frontal.so/gtm-apis/enrichment-apis/clearbit-api-review) | Firmographics, Technographics, Intent and news | $20/HubSpot seat/mo | Not sold by the unit | No | | [PhantomBuster](https://frontal.so/gtm-apis/source-apis/phantombuster-api-review) | Firmographics | $56/mo annual | $2.80 per execution hour | Yes | | [Wiza](https://frontal.so/gtm-apis/enrichment-apis/wiza-api-review) | Firmographics | $50 one-time | $0.05 per email, 2 credits | No | | [Reverse Contact](https://frontal.so/gtm-apis/enrichment-apis/reverse-contact-api-review) | Firmographics | $100 one-time | $0.02 per credit | Yes | | [Crustdata](https://frontal.so/gtm-apis/enrichment-apis/crustdata-api-review) | Firmographics, Technographics, Job postings, Intent and news | Quote only | Sold in credits; no public dollar price for a credit | Yes | | [Dropcontact](https://frontal.so/gtm-apis/enrichment-apis/dropcontact-api-review) | Firmographics | €29/mo | €0.01975 an email found, priced in euros (€79 for 4,000) | Yes | Read from each vendor's own pages on 24 October 2026, and each review carries the full rate card.

The catch is that credits and seats are coupled, so the API inherits a per-seat price even when no human logs in. - People and organization search across Apollo's own database - Enrichment returns 1 credit for email, 9 if a mobile comes back - Sequence, contact and task endpoints cost 0 credits - Credits are granted per seat per YEAR, not per month From $49 /seat/mo [Read the review of the Apollo API](https://frontal.so/gtm-apis/enrichment-apis/apollo-api-review) [site for Apollo (opens in a new tab)](https://go.frontal.so/apollo) ### [Clay](https://frontal.so/gtm-apis/enrichment-apis/clay-api-review) Best orchestration layer Motion Source Enrich Signal Model MCP server Free tier Clay is not really an enrichment API, it is the router in front of everybody else's. You pay in actions for the work and data credits for the data rather than per record, and the waterfall logic that would take a week to build yourself is a column setting. - Waterfall across 150+ data providers without separate contracts - Two meters, actions and data credits, and neither is charged on a lookup that finds nothing - Free plan runs 500 actions a month with no phone enrichment From $167 /mo annual [Read the review of the Clay API](https://frontal.so/gtm-apis/enrichment-apis/clay-api-review) [site for Clay (opens in a new tab)](https://go.frontal.so/clay) ### [People Data Labs](https://frontal.so/gtm-apis/enrichment-apis/people-data-labs-api-review) Best for building on top of Motion Source Enrich Model Free tier PDL sells the dataset rather than the workflow, and its standard subscription agreement licenses you to show its data to your own customers inside your product, which few other self-serve plans here grant by default. It is not a resale license: you may not resell the data or give your users programmatic access to a substantial part of it. That license is the reason to pick it over a cheaper per-email tool. - Person, company, job title and school datasets under one key - Free plan obfuscates emails and phones until you upgrade - Bulk and search endpoints designed for warehouse loads From $98 /mo [Read the review of the People Data Labs API](https://frontal.so/gtm-apis/enrichment-apis/people-data-labs-api-review) [site for People Data Labs (opens in a new tab)](https://www.peopledatalabs.com/) ### [LeadMagic](https://frontal.so/gtm-apis/enrichment-apis/leadmagic-api-review) Best priced per operation Motion Source Enrich Verify Signal Model MCP server Every operation has a stated credit cost, credits come off only when a lookup succeeds, and search is free in the app and unmetered on the API from Professional. The MCP server ships on every tier, including the cheapest. - Email finder 1 credit, mobile 5, validation 0.25, job change 3 - Credits deducted on valid results only, never on a miss - Search is free in the app; the Search API is 1 credit a result on Essential and Growth, unmetered from Professional From $99 /mo [Read the review of the LeadMagic API](https://frontal.so/gtm-apis/enrichment-apis/leadmagic-api-review) [site for LeadMagic (opens in a new tab)](https://www.leadmagic.io/) ### [Findymail](https://frontal.so/gtm-apis/enrichment-apis/findymail-api-review) A refund if your bounce rate passes 5% Motion Enrich Verify Model MCP server Findymail verifies at the moment it finds, so you are not paying twice for the same address. It is the only provider here that puts a number on deliverability and refunds against it: above a 5% bounce rate, the credits come back. - Under 5% bounce rate or the credits are refunded - Duplicates found in the last 30 days cost nothing - Mobile numbers are non-EU only, at 10 credits each - API on every plan; usage-based plans include 1, 5 or 20 seats, credit plans are for reselling or embedding From $99 /mo [Read the review of the Findymail API](https://frontal.so/gtm-apis/enrichment-apis/findymail-api-review) [site for Findymail (opens in a new tab)](https://www.findymail.com/) ### [Hunter](https://frontal.so/gtm-apis/enrichment-apis/hunter-api-review) Best documented starter Motion Enrich Verify Model MCP server Free tier Hunter has been the default first API in this category for a decade, and the documentation shows it. Coverage is thinner than the newer waterfall tools, but nothing else here is as fast to get a working call out of. - Domain Search returns every known address on a domain - Free tier of 50 credits a month, enough to prototype against - Annual billing drops Starter from $49 to $34 a month From $49 /mo [Read the review of the Hunter API](https://frontal.so/gtm-apis/enrichment-apis/hunter-api-review) [site for Hunter (opens in a new tab)](https://hunter.io/) ### [TheirStack](https://frontal.so/gtm-apis/signal-apis/theirstack-api-review) Best for hiring and technology signal with filter depth Motion Signal Source Model MCP server No monthly floor Job postings are the cheapest honest intent signal in B2B, because a company hiring three SDRs has already decided to spend. TheirStack sells that as rows rather than as a dashboard, and the credits roll over for a year. - One-time packs from $109 for 1,000 company credits - Monthly subscription from $49 for 1,500 API credits - Unused paid credits roll over for 12 months, packs and subscriptions alike From $49 /mo [Read the review of the TheirStack API](https://frontal.so/gtm-apis/signal-apis/theirstack-api-review) [site for TheirStack (opens in a new tab)](https://theirstack.com/) ### [Crunchbase](https://frontal.so/gtm-apis/signal-apis/crunchbase-api-review) Best for funding and company signal Motion Source Signal Model MCP server Crunchbase is where most teams look first for funding rounds, headcount and company history, and the API serves the same data that powers the site. Like Cognism, Salesloft and Outreach, it publishes no rate card at all, and it withdrew its free Basic tier, so access now starts with a sales call. - No published pricing. Access is quoted, through sales or your CSM - The free Basic API is closed: existing keys work, new ones are not issued - 200 requests a minute and 3 concurrent requests, per key From Quote only [Read the review of the Crunchbase API](https://frontal.so/gtm-apis/signal-apis/crunchbase-api-review) [site for Crunchbase (opens in a new tab)](https://www.crunchbase.com/) ### [Cognism](https://frontal.so/gtm-apis/enrichment-apis/cognism-api-review) Best for notified, DNC-screened contact data Motion Source Enrich Signal Model MCP server Per seat Cognism sells a compliance posture as much as a dataset: it notifies the business contacts it holds within GDPR timeframes and scrubs its phone data against 15 Do Not Call and TPS registries. The API meters usage three separate ways, and the one that stops you first is usually not the one you budgeted for. - Search tokens meter rows returned, credits meter contacts revealed - 500 requests a minute per operation, each with its own window - No published price. Two plans, both with 5 seats included From Quote only [Read the review of the Cognism API](https://frontal.so/gtm-apis/enrichment-apis/cognism-api-review) [site for Cognism (opens in a new tab)](https://www.cognism.com/) ### [Lusha](https://frontal.so/gtm-apis/enrichment-apis/lusha-api-review) Best published credit costs for contact data Motion Source Enrich Signal Model MCP server Free tier Per seat Lusha publishes what every operation costs to the credit: an email is 1, a phone number is 5, a recorded call is 8. What it does not publish is how fast you may ask for them. Rate limits are per plan across three windows and the numbers are an account manager conversation. - An email costs 1 credit, a phone number costs 5 - Per-credit cost barely moves across tiers, $0.094 to $0.087, so volume buys seats not discounts - Rate limits run per minute, hour and day, and are unpublished From $37.45 /mo annual [Read the review of the Lusha API](https://frontal.so/gtm-apis/enrichment-apis/lusha-api-review) [site for Lusha (opens in a new tab)](https://www.lusha.com/) ### [ZoomInfo](https://frontal.so/gtm-apis/enrichment-apis/zoominfo-api-review) Enterprise depth, now with a self-serve API Motion Source Enrich Signal Model MCP server Free tier No monthly floor Per seat ZoomInfo is the incumbent most of these comparisons are really against, and it now sells two ways. The packages are still quoted, but GTM AI, its self-serve route, publishes a pay-as-you-go price for the API, MCP server and CLI: 1,000 data credits free, then $0.38 a data credit at the $1,000 spend tier. Search is free; enriching a record costs one credit. - 1,000 data and 1,000 AI credits free, then top-ups from $20 - $0.38 a data credit at the $1,000 tier; search and lookup are free - Mobile numbers and records under management are Enterprise only From $0.38 /data credit [Read the review of the ZoomInfo API](https://frontal.so/gtm-apis/enrichment-apis/zoominfo-api-review) [site for ZoomInfo (opens in a new tab)](https://www.zoominfo.com/) ### [RocketReach](https://frontal.so/gtm-apis/enrichment-apis/rocketreach-api-review) API and MCP on the cheapest paid tier Motion Source Enrich Model MCP server Per seat RocketReach puts API and MCP access on every paid tier including the $33 one, and its per-export price genuinely falls with volume rather than staying flat. Exports are annual allowances rather than monthly credits, Essentials is email only, and the rate limits are published per plan. - MCP and API access on all three paid plans - 1,200 exports a year at $399, up to 20,000 at $1,699 - Per export: $0.33 on Essentials, $0.085 on Ultimate From $33 /mo annual [Read the review of the RocketReach API](https://frontal.so/gtm-apis/enrichment-apis/rocketreach-api-review) [site for RocketReach (opens in a new tab)](https://rocketreach.co/) ### [Clearbit](https://frontal.so/gtm-apis/enrichment-apis/clearbit-api-review) No longer sold on its own, now HubSpot data enrichment Motion Enrich Signal Model Per seat Clearbit is no longer a product you can buy on its own. clearbit.com now reads "Clearbit has joined HubSpot" and offers a customer login rather than a signup, and the enrichment is now HubSpot data enrichment, included with paid seats on Starter and up. HubSpot says enrichment does not consume HubSpot Credits; its intent signals do, at 10 credits a company a month. - clearbit.com offers a customer login, not a signup - Enrichment is now HubSpot data enrichment, in the paid seat - Enrichment uses no HubSpot Credits; intent is 10 credits a company a month From $20 /HubSpot seat/mo [Read the review of the Clearbit API](https://frontal.so/gtm-apis/enrichment-apis/clearbit-api-review) [site for Clearbit (opens in a new tab)](https://clearbit.com/) ### [PhantomBuster](https://frontal.so/gtm-apis/source-apis/phantombuster-api-review) Best for running LinkedIn automations from code Motion Source Enrich Engage Model MCP server PhantomBuster runs Phantoms, prebuilt automations that extract and enrich from over 15 platforms, LinkedIn among them, through your own accounts. The API does not scrape anything itself: it launches an agent and reads what the agent produced, and the bill is execution hours, slots and email credits rather than requests. - Plans meter execution time: 20, 80 or 300 hours a month - No published request rate limit; slots cap how many Phantoms run at once - Hosted MCP server with OAuth on every plan From $56 /mo annual [Read the review of the PhantomBuster API](https://frontal.so/gtm-apis/source-apis/phantombuster-api-review) [site for PhantomBuster (opens in a new tab)](https://phantombuster.com/) ### [Wiza](https://frontal.so/gtm-apis/enrichment-apis/wiza-api-review) LinkedIn URLs in, verified emails and mobiles out, paid per hit Motion Source Enrich Model No monthly floor Wiza sells its API apart from its seat plans: a prepaid balance of API credits at $0.025 each, from a $50 minimum, that anyone can buy without a subscription. A verified email costs 2 credits, a phone 5 and a profile 1, and nothing is charged when nothing is found. None of the individual seat plans, even the unlimited annual ones, lists API access. - API credits at $0.025 each, 2,000 minimum for $50, no plan required - 2 credits a verified email, 5 a phone, 1 a profile, 0 on a miss - Async reveals: 15 requests a second, then 5 or 15+ running at once by API tier From $50 one-time [Read the review of the Wiza API](https://frontal.so/gtm-apis/enrichment-apis/wiza-api-review) [site for Wiza (opens in a new tab)](https://wiza.co/) ### [Reverse Contact](https://frontal.so/gtm-apis/enrichment-apis/reverse-contact-api-review) Unlimited profile lookups for a team that starts from LinkedIn URLs Motion Enrich Source Model MCP server Free tier Reverse Contact sells person and company data two ways: credit packs from $100 for 5,000, or unlimited monthly plans priced by endpoint family. Go at $249 makes profile fetches from a social URL unlimited, Plus at $449 adds search and Max at $699 adds enrichment from an email, a name or a domain.

Funding, hiring and tech stack are specialist datasets, and the provider that has the one your scoring weighs is the shortlist. 02 ### How the record is keyed A domain is the cleanest key and most providers accept one. A company name is ambiguous, and a LinkedIn URL depends on which provider can fetch it and under what terms. 03 ### Freshness against cost Load slow-moving firmographics once from a broad provider, then call signal providers only for accounts that changed. Paying a signal provider to re-read a static field is the usual waste. 04 ### What the license lets you show Using company data in your own CRM is covered almost everywhere. Showing it to your customers is not: Crunchbase forbids it without a license that says so, while People Data Labs' standard terms cover showing its data inside your product, though not reselling it.

FAQ ## Company data APIs, answered **How many company data APIs are in this directory?** 18, chosen by what each one returns rather than by hand, and each with its own review carrying the price, the rate limit and the auth method read from the vendor's own pages. **Which company data APIs have a free tier?** Apollo, Clay, People Data Labs, Hunter, Lusha, ZoomInfo, Reverse Contact, Crustdata and Dropcontact. What each free tier includes differs a lot, so the review says what you actually get. **Which company data API is cheapest?** Of the 6 that price per credit, Apollo at $0.0196. The others meter a different unit, so their rates are not comparable number for number, and a monthly floor or a charge on a miss changes the bill either way. **How are company data APIs billed?** 13 of the 18 publish a per-unit rate; the rest sell a plan, quote on request or price in another currency, and each review says which. **Which ones ship an MCP server?** Apollo, Clay, LeadMagic, Findymail, Hunter, TheirStack, Crunchbase, Cognism, Lusha, ZoomInfo, RocketReach, PhantomBuster, Reverse Contact, Crustdata and Dropcontact. The ones the directory reviews live on the MCP page with the connect details. **What is a company data API?** An API that returns a company record from a domain, a name or an identifier: industry, headcount and location as a base, and from some providers funding, technologies and job postings on top. It is the account half of the data that outbound and scoring run on. **Is there a public company data API for SEC filings here?** No. None of the providers in this directory sells filings or audited financials. For listed-company financials the regulator's own data is the source; the providers here cover private-company firmographics, funding, stack and hiring. **Can I get LinkedIn company data by API?** What LinkedIn's own API grants, and to whom, is on the LinkedIn API page. Providers such as Reverse Contact, PhantomBuster and Crustdata reach company profiles their own ways, each with its own terms. **Which company data API has funding data?** Crunchbase is the one built around it: funding rounds, investors, acquisitions and company history. It publishes no price, so access starts with a quote.
