They read it from three different places, and where it comes from decides what it can tell you. Short answer [TheirStack](https://frontal.so/gtm-apis/signal-apis/theirstack-api-review) reads a company's stack from its job postings and prices per company from $49. Apollo, [ZoomInfo](https://frontal.so/gtm-apis/enrichment-apis/zoominfo-api-review) and [Lusha](https://frontal.so/gtm-apis/enrichment-apis/lusha-api-review) return technographics inside a wider company record, so pick one of them when you are buying that record anyway.

The answer is only as good as the place it was read from, and the providers here read it from three different places. Some scan the website itself, some read the company's job postings, and some carry the stack as one field on a company record they already sell. Those are different products that happen to share a label. A website scan sees the script tags, the payment widget and the analytics library on a public page, including on a small shop that never hires. A job posting reveals the systems a company is about to spend money on, because it is hiring somebody to run them. A field on an enrichment record is whatever the provider's own index holds, refreshed on its schedule rather than yours. The directory carries the posting-led source as a full review, TheirStack, and the website scanner as a comparison-only record, BuiltWith. Most of the rest are enrichment providers that return technographics beside firmographics, Apollo, [Crustdata](https://frontal.so/gtm-apis/enrichment-apis/crustdata-api-review) and ZoomInfo among them. They are the cheapest route when you already enrich people with one of them. So the first decision is not which vendor. It is which of the three questions you are asking: what is on the site, what are they hiring for, or what does a broad company record say. The rest of this page sorts the providers by that question, then by what a lookup costs and how fast you can ask. Where it comes from ## Website, job postings or a company record The source is the part a vendor page rarely leads with, and it is the part that decides whether a row is useful for outbound. A stack read off a website is evidence that a technology is installed. A stack read off job postings is evidence that a team is working in it this quarter. Neither says the other. The three sources line up with the providers like this, and each line is read off that provider's own record: - **The website itself.** BuiltWith detects the technologies on a site and sells them two ways: one domain at a time by the credit, or the list of every site using a technology on a monthly plan. It is carried here as a comparison-only record, which is why it is not in the grid below. [DataForSEO](https://frontal.so/gtm-apis/signal-apis/dataforseo-api-review)'s Domain Analytics API also detects the technologies on a site, from $0.012 a task, pay as you go. - **Job postings.** TheirStack sells job postings and technographics as rows: every posting a company has published, the technologies those postings and its stack reveal, and the firmographics around them. Hiring for a system is a budget signal as well as a stack signal. - **A field on the company record.** Apollo returns a technology stack with its organization enrichment, Crustdata adds technographics as a paid add-on to a company record, and Clearbit's successor, HubSpot data enrichment, which HubSpot launched as Breeze Intelligence, covers more than 40 attributes that include technologies. ZoomInfo, Lusha and [RocketReach](https://frontal.so/gtm-apis/enrichment-apis/rocketreach-api-review) carry technographics on their company data too. - **A filter rather than a field.** [Cognism](https://frontal.so/gtm-apis/enrichment-apis/cognism-api-review) lists technographic filters among its prospecting features, and Crustdata's docs say its search filters on technographics without returning them. A filter builds a list; it does not hand you the stack to store. Pick the source first, then the vendor. A team selling an integration wants the posting signal; a team selling to ecommerce sites that rarely hire wants the website scan. What it costs ## A lookup, a list and two currencies Technographic pricing comes in more shapes than any other data type in this directory, because the providers are selling different units. Compare the unit before you compare the number. [BuiltWith](https://frontal.so/gtm-apis/alternatives/builtwith-alternatives) is the cleanest to read. A domain lookup through its API is 1 credit, $0.0495 at the entry rate, with a 2,000 credit minimum for an account. The lists, which are what most sales teams buy BuiltWith for, are not sold by the credit at all: the Lists API needs a plan at $295, $495 or $995 a month. TheirStack runs two currencies, and that is the trap on its page. Company credits come in one-time packs from $109 for 1,000, which is the app's currency; the directory records the API credit. API credits are a separate monthly subscription from $49 for 1,500, about $0.0327 each, and the API bills 3 of them for a company it returns. The two balances buy different things, so check which one a quote is in. [Apollo](https://frontal.so/gtm-apis/enrichment-apis/apollo-api-review) returns the stack on organization enrichment for 1 credit, and an Apollo credit works out at $0.0196, because Basic grants 30,000 credits a seat a year for $49 a seat a month billed annually. The cheap credit is cheap only if you were buying the seat anyway. Crustdata charges 2 credits for a company record and 2 more when technographics come back, and it does not publish the dollar price of a credit. The rest price the stack inside something broader. ZoomInfo's self-serve route charges $0.38 a data credit, with search free. [Clearbit](https://frontal.so/gtm-apis/enrichment-apis/clearbit-api-review) is now HubSpot data enrichment, included with paid HubSpot seats from Starter and spending no HubSpot Credits, so its price is the seat. Cognism publishes no price at all. Each provider's review carries the full rate card. Two jobs ## Listing by technology is not enriching a domain Two different calls hide behind "technographic data". One takes a domain you already have and returns its stack. The other takes a technology and returns every company that runs it. The first is enrichment; the second is list building, and it is usually the one a sales team actually wants. The list is where the prices diverge. BuiltWith gates it behind a monthly plan from $295. TheirStack filters companies by technology through its API at 3 API credits a company with no separate list plan, out of the same monthly API credits, and can push new matching companies to a webhook as they appear. Crustdata filters a company search on technographics and bills 1 extra credit a result on top of the 0.03 base, so size the result set before you run it at scale. Enrichment by domain is cheaper and more common. Apollo, Crustdata, ZoomInfo, Clearbit through HubSpot and BuiltWith all do it, and Findymail lists technologies by domain among its endpoints, each with its own credit rule. If you already enrich people with one of these, the stack may be one more field on a call you already make. The honest answer for most teams is both: build the list from the source that fits the motion, then enrich the survivors with whatever provider already sits in your [waterfall](https://frontal.so/gtm-apis/stacks/waterfall-enrichment). Throughput ## Rate limits, and one rule that deletes data Technographic jobs tend to be backfills, a whole account list at once, so the rate limit matters more here than on a one-at-a-time lookup. The limits differ by two orders of magnitude. BuiltWith allows 8 concurrent requests and 10 a second, then returns a 429. Its bulk jobs take up to 5,000 domains, and it deletes the results after the first successful read, so a pipeline that fails between fetching and storing has paid for data it no longer has. Store before you parse. TheirStack allows 4 requests a second once you have paid, shared across job search, company search and technographics; free accounts are also capped at 10 a minute and 400 a day. Crustdata limits company enrichment to 15 requests a minute and caps batch jobs at 5 in flight by default, so a 100,000 domain backfill runs through batch or not at all. Apollo's enrichment runs at 1,000 requests a minute with no hourly or daily cap. If the job is a backfill, read the batch rules before the per-second number; if it is a live lookup at the moment an account is created, the per-second number is the one that matters. In outbound ## Turning a stack into a reason to write A stack on its own is a filter, not a message. The teams that get value out of a technographic data API use it in one of three ways, and each one wants a different source. The first is fit: only sell to companies running a system you integrate with. That is a list-building job, and the cheapest honest route is a technology filter that returns companies rather than one lookup per domain, which is what TheirStack's company search and BuiltWith's Lists plans are for. The second is timing. A company posting for an administrator of a platform you replace, or for an engineer in the language your product targets, is telling you about budget this quarter. Job postings are the source that carries that, which is why the posting-led provider is the usual answer for a sales team rather than a marketing one. The third is personalization at the moment of research: an agent or a rep looking at one account and wanting the stack beside the contacts. That is enrichment by domain, and it is cheapest from a provider you already call for people, as one more field on the same request. Write down which of the three you are doing before you buy, because a team that wants timing and buys a website scan will get an accurate list of companies that are not in market. Agents ## Asking for the stack from an agent Several of these ship an [MCP server](https://frontal.so/gtm-apis/mcp-servers), which matters when the thing asking is an assistant researching an account rather than a script. Of the 11, ten publish one, TheirStack, Apollo and Crustdata among them, and so does BuiltWith, which also accepts per-call x402 payments without an account. An agent that can ask for the stack beside the contacts, on one key, saves a second vendor and a second integration. It does not change which source the stack came from, so the first decision on this page still stands. Side by side ## The 11 providers, on the figures that decide it Entry price and unit cost are read from each vendor's own pricing page.

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) ### [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/) ### [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/) ### [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.

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/) ### [DataForSEO](https://frontal.so/gtm-apis/signal-apis/dataforseo-api-review) SERP data from $0.60 per 1,000, if you can wait for it Motion Signal Source Model MCP server No monthly floor DataForSEO is pay as you go across a long list of SEO APIs, and the SERP API is priced by queue: $0.60 per 1,000 SERPs if you can wait about five minutes, $2.00 if you need it in six seconds. Search operators in the keyword multiply the price by five each. - Google SERP $0.60, $1.20 or $2.00 per 1,000, by queue - Each search operator in a keyword is x5 the base price - $50 minimum payment, a $1 trial credit and a free Sandbox From $0.60 /1k SERPs [Read the review of the DataForSEO API](https://frontal.so/gtm-apis/signal-apis/dataforseo-api-review) [site for DataForSEO (opens in a new tab)](https://dataforseo.com/) ### [Crustdata](https://frontal.so/gtm-apis/enrichment-apis/crustdata-api-review) Search wide for pennies of a credit, then pay only for the fields you keep Motion Source Enrich Signal Model MCP server Free tier Crustdata prices every call in credits by what it returns: a search result is 0.03 credits and an empty search is free, a person profile is 1 credit and each contact field is an add-on on top. What it does not publish is what a credit costs in dollars. New accounts get $20 in credits, self-serve packs are priced in the dashboard, and enterprise plans start at four figures a month. - Search at 0.03 credits a result, and a search that returns nothing is free - Person enrich from 1 credit, up to 9 with every contact add-on - $20 in free credits; the dollar rate of a credit is not on the public pages - Hosted MCP server, and limits set per endpoint, from 10 to 30 requests a minute From Quote only [Read the review of the Crustdata API](https://frontal.so/gtm-apis/enrichment-apis/crustdata-api-review) [site for Crustdata (opens in a new tab)](https://crustdata.com/) Buyer's guide ## Four things that decide this choice In the order they cost you money. 01 ### Where the stack is read from A website scan, a job posting and a field on an enrichment record answer different questions. Decide whether you need what is installed, what is being hired for, or what a broad record says, before you compare a single price. 02 ### Whether you need the list or the lookup Listing every company that runs a technology is a different product from enriching a domain you already hold, and it is usually priced as a plan rather than a credit. Price the call you will actually make most. 03 ### Which currency the price is in TheirStack sells company credits and API credits at different rates, Apollo's credit is tied to a seat, and Crustdata does not publish a dollar figure for a credit. Write the unit and the period next to every number before you divide. 04 ### Backfill throughput and storage rules A technographic job is usually a backfill. Check the batch limits, the concurrency cap and any rule that deletes results after a read, because a failed run on a delete-on-read API is paid for twice.

FAQ ## Technographic data APIs, answered **How many technographic data APIs are in this directory?** 11, 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 technographic data APIs have a free tier?** Apollo, Clay, Lusha, ZoomInfo and Crustdata. What each free tier includes differs a lot, so the review says what you actually get. **Which technographic data API is cheapest?** Of the 3 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 technographic data APIs billed?** 8 of the 11 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, Findymail, TheirStack, Cognism, Lusha, ZoomInfo, RocketReach, DataForSEO and Crustdata. The ones the directory reviews live on the MCP page with the connect details. **What is a technographic data API?** An API that returns the software a company uses. The providers here read it from the company's website, from its job postings, or from their own company index, and the source decides whether a row means installed, being hired for, or simply recorded. **Is BuiltWith in this directory?** As a comparison-only record, so it does not appear in the grid. Its domain lookup is $0.0495 a credit at the entry rate, and its technology lists need a plan from $295 a month; the BuiltWith alternatives page compares it with TheirStack, Apollo and Crustdata. **Which technographic data API builds a list by technology without a separate list plan?** TheirStack filters companies by technology through the same API credits as every other call, 3 a company, from $49 a month for 1,500. BuiltWith sells the same job as a Lists plan from $295 a month, on top of its lookup credits. **Can I get technographics from a provider I already use for contacts?** Often. Apollo returns a technology stack on organization enrichment for 1 credit, Crustdata adds it to a company record for 2 extra credits, and HubSpot customers on paid seats get technologies through HubSpot data enrichment.
