--- title: "People data API: who returns which person fields" description: "Every people data API in the directory, compared on the person fields it returns, how it finds them, what a miss costs and what its license allows." url: https://frontal.so/gtm-apis/people-data-apis updated: 2026-11-12 --- By data · People data APIs # People data API: *the person record, field by field* Seventeen providers in this directory return a person record by API. They differ on which fields come back, how each one finds them, and what the license lets you do with the result. Short answer For work email by the credit, Apollo at $0.0196 on a seat, or LeadMagic and Findymail at $0.0198. [People Data Labs](https://frontal.so/gtm-apis/enrichment-apis/people-data-labs-api-review) when the person record goes inside a product you sell, and [RocketReach](https://frontal.so/gtm-apis/enrichment-apis/rocketreach-api-review) when you want a per-export price that falls with volume.

That means the work email, sometimes a personal email and a mobile, the current title and, from a few providers, the history of where that person worked before. This page sorts the directory by that record rather than by price. The cost of a work email is on [contact enrichment APIs](https://frontal.so/gtm-apis/enrichment-apis), which ranks the same providers per record found. Here the question is what each one can hand back at all, because a cheap email is no use if the row you needed was a mobile. One overlap is worth naming up front: People Data Labs has a product name that is almost the phrase people data API, so a search for one often means the other. It is one of the providers on this page, with [its own full review](https://frontal.so/gtm-apis/enrichment-apis/people-data-labs-api-review), and it is the one whose license is written for putting the data inside a product you sell. The list is not typed by hand. A provider is here because its record says it returns a work email, a personal email or a mobile, its primary job is sourcing or enrichment, and it is not a search or scraping API. Change the record and the page changes with it. The fields ## Which person fields each provider returns Every provider here returns a work email. The fields after that are where they split, and they split hard, so start from the field your workflow cannot do without and work backwards to the shortlist. A mobile is the field that moves the bill most, because nobody prices it like an email. It costs 9 Apollo credits against 1 for an email, 5 Lusha credits, and 10 on [Prospeo](https://frontal.so/gtm-apis/enrichment-apis/prospeo-api-review), where an email is 1. - **Work email**: all of them, which is why it is the least useful way to choose between them. - **Personal email**: Clay, People Data Labs, FullEnrich, RocketReach, Wiza, [Reverse Contact](https://frontal.so/gtm-apis/enrichment-apis/reverse-contact-api-review) and Crustdata. [FullEnrich](https://frontal.so/gtm-apis/enrichment-apis/fullenrich-api-review) charges 3 credits for one against 1 for a work email. - **Mobile**: most of them, with conditions. [Findymail](https://frontal.so/gtm-apis/enrichment-apis/findymail-api-review) returns non-EU mobiles only, and [ZoomInfo](https://frontal.so/gtm-apis/enrichment-apis/zoominfo-api-review) keeps mobiles for its Enterprise packages. - **Job changes**: Clay, [LeadMagic](https://frontal.so/gtm-apis/enrichment-apis/leadmagic-api-review), Cognism, Lusha, ZoomInfo and [Crustdata](https://frontal.so/gtm-apis/enrichment-apis/crustdata-api-review) carry the change itself as data. LeadMagic prices its Job Change Detector at 3 credits. - **A LinkedIn profile URL as the starting point**: Wiza, Reverse Contact, [PhantomBuster](https://frontal.so/gtm-apis/source-apis/phantombuster-api-review) and Crustdata are built around it, though most of the providers here return a profile field on the record. What LinkedIn itself allows is on the [LinkedIn API page](https://frontal.so/gtm-apis/linkedin-api). Read the gaps as seriously as the ticks. Hunter, for example, returns work emails and company data and no phones at all, which is the right shape for a domain-led motion and the wrong one for a calling team. How it finds the person ## A database lookup and a real-time finder are different products Most of these providers answer from a database they maintain. Apollo searches its own records, People Data Labs sells person, company, job title and school datasets, and ZoomInfo and Cognism sell access to databases of their own. A lookup there is fast, and it is only as current as the record it reads. Dropcontact is the clearest example of the other kind. Its pricing page says it works "exclusively with algorithms" on EU servers and keeps no contact database, so a contact sent without a company or a website is an error: there is nothing to look the person up in. Findymail sits between the two, verifying each address at the moment it finds it. Waterfalls are a third shape. Clay routes one row across 150 plus providers and FullEnrich runs the same logic as a single API call with a single bill. You are buying coverage across many databases rather than the depth of one, and both pages say what that costs. Crustdata and Reverse Contact mix the first two. Crustdata answers from its own index and also offers live endpoints at a lower rate limit, and Reverse Contact keeps live refreshes on credits even on its unlimited plans. If freshness matters more than speed, check which endpoint a job calls before you size it. None of this shows in a field list, which is why two providers that both tick "work email" can return different addresses for the same person on the same day. License and compliance ## What you are allowed to do with the person record The price tells you what a lookup costs. The license tells you what you may do with the row afterwards, and for anything beyond your own outbound it decides the shortlist before price does. People Data Labs' 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, and that is the reason to pay $0.28 a record when a work email elsewhere costs $0.02. It is not a resale license: you may not resell the data, give your users programmatic access to a substantial part of it, or build anything that competes with PDL. Apollo and FullEnrich sell an embedded right under a separate reseller agreement, and Findymail through its credit-based plans. Cognism sells a compliance posture as much as a dataset. It notifies the business contacts it holds within GDPR timeframes and screens its phone data against 15 Do Not Call and TPS registries, which matters most for a team calling into Europe. Dropcontact takes the opposite route to the same goal. With no contact database there is nothing held to notify anyone about, and the processing stays on EU servers. It is also priced in euros only, which every table on this site shows as it is rather than converting. If a vendor's review says nothing about resale, assume your license covers your own use only and ask before you build a product on the data. Search and enrich ## Search finds the people, enrich completes them, and they are billed apart Most people data APIs have two halves. Search returns people matching criteria, a title, a company size, a location. Enrich takes one known person and fills in the contact fields. The two are metered differently, and the difference decides what a list costs to build. Search is cheap or free on several of them. LeadMagic runs people, company and jobs 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, and ZoomInfo charges nothing to search or look up and one data credit to enrich a record. On Apollo, the people search API is free and the enrichment call next to it is not. Others meter the search itself. Cognism spends search tokens on every row returned and credits on every contact revealed, and Crustdata charges 0.03 credits a search result, nothing for an empty search, and from 1 credit for a person profile up to 9 with every contact add-on. The other half of the bill is what a miss costs. LeadMagic, Wiza, Reverse Contact and Dropcontact charge nothing when nothing comes back. Clay bills in actions, so a lookup that fails inside a [waterfall](https://frontal.so/gtm-apis/stacks/waterfall-enrichment) still counts, which is the arithmetic the [Apollo vs Clay page](https://frontal.so/gtm-apis/compare/apollo-vs-clay) works through. Build the list with the cheap search, enrich only the rows you will actually contact, and a 10,000-row list stops costing 10,000 lookups. Rate limits follow the same split: Crustdata allows 30 searches a minute against 15 person enrichments, and Cognism gives each operation its own 500-a-minute window, so a pipeline that searches wide and enriches narrow is also the one that runs fastest. Where to start ## Which people data APIs suit which starting point The input you already hold narrows the list faster than any feature comparison. Each line below names providers whose own pages document that starting point. - **A name and a company or domain**: Dropcontact needs exactly this, and Hunter, Prospeo and Findymail are built around it. - **A LinkedIn profile URL**: Wiza, Reverse Contact and Crustdata. Wiza also accepts Sales Navigator and Recruiter URLs. - **An email you already have**: Reverse Contact enriches from an email, a name or a domain on its Max plan, and keeps the contact fields on credits. - **Only search criteria**: Apollo, LeadMagic, ZoomInfo, Cognism and Crustdata let you search for the people before you enrich them. - **A list you need completed at maximum coverage**: a waterfall, Clay or FullEnrich, with the cost of each provider tried priced in. If two inputs are possible, pick the one your source data carries cleanly. A LinkedIn URL is unambiguous where a company name often is not, and the company half of the same row is on [company data APIs](https://frontal.so/gtm-apis/company-data-apis). Side by side ## The person fields, and what one lookup costs Returns lists the person fields 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 export, an email found. | Provider | Returns | Entry price | Unit cost | MCP server | | --- | --- | --- | --- | --- | | [Apollo API](https://frontal.so/gtm-apis/enrichment-apis/apollo-api-review) | Work email, Mobile phone, LinkedIn profile | $49/seat/mo | $0.0196 per credit | Yes | | [Clay](https://frontal.so/gtm-apis/enrichment-apis/clay-api-review) | Work email, Personal email, Mobile phone, Job changes, LinkedIn profile | $167/mo annual | $0.0452 per data credit | Yes | | [People Data Labs](https://frontal.so/gtm-apis/enrichment-apis/people-data-labs-api-review) | Work email, Personal email, Mobile phone, LinkedIn profile | $98/mo | $0.28 per record | No | | [LeadMagic](https://frontal.so/gtm-apis/enrichment-apis/leadmagic-api-review) | Work email, Mobile phone, Job changes, LinkedIn profile | $99/mo | $0.0198 per credit | Yes | | [Findymail](https://frontal.so/gtm-apis/enrichment-apis/findymail-api-review) | Work email, Mobile phone, LinkedIn profile | $99/mo | $0.0198 per credit | Yes | | [Prospeo](https://frontal.so/gtm-apis/enrichment-apis/prospeo-api-review) | Work email, Mobile phone, LinkedIn profile | $49/mo | $0.0245 per credit | Yes | | [Hunter](https://frontal.so/gtm-apis/enrichment-apis/hunter-api-review) | Work email | $49/mo | $0.0245 per credit | Yes | | [FullEnrich](https://frontal.so/gtm-apis/enrichment-apis/fullenrich-api-review) | Work email, Personal email, Mobile phone, LinkedIn profile | $29/mo | $0.055 per credit, 1,000-credit plan | Yes | | [Cognism](https://frontal.so/gtm-apis/enrichment-apis/cognism-api-review) | Work email, Mobile phone, Job changes | Quote only | Not sold by the unit | Yes | | [Lusha](https://frontal.so/gtm-apis/enrichment-apis/lusha-api-review) | Work email, Mobile phone, Job changes | $37.45/mo annual | $0.087 per credit | Yes | | [ZoomInfo](https://frontal.so/gtm-apis/enrichment-apis/zoominfo-api-review) | Work email, Mobile phone, Job changes | $0.38/data credit | $0.38 per data credit | Yes | | [RocketReach](https://frontal.so/gtm-apis/enrichment-apis/rocketreach-api-review) | Work email, Personal email, Mobile phone | $33/mo annual | $0.25 per export on Pro, the first plan with phones | Yes | | [PhantomBuster](https://frontal.so/gtm-apis/source-apis/phantombuster-api-review) | LinkedIn profile, Work email | $56/mo annual | $2.80 per execution hour | Yes | | [Wiza](https://frontal.so/gtm-apis/enrichment-apis/wiza-api-review) | Work email, Personal email, Mobile phone, LinkedIn profile | $50 one-time | $0.05 per email, 2 credits | No | | [Reverse Contact](https://frontal.so/gtm-apis/enrichment-apis/reverse-contact-api-review) | Work email, Personal email, Mobile phone, LinkedIn profile | $100 one-time | $0.02 per credit | Yes | | [Crustdata](https://frontal.so/gtm-apis/enrichment-apis/crustdata-api-review) | Work email, Personal email, Mobile phone, Job changes, LinkedIn profile | Quote only | Sold in credits; no public dollar price for a credit | Yes | | [Dropcontact](https://frontal.so/gtm-apis/enrichment-apis/dropcontact-api-review) | Work email, LinkedIn profile | €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/) ### [Prospeo](https://frontal.so/gtm-apis/enrichment-apis/prospeo-api-review) Low entry for verified email, with rollover Motion Source Enrich Model MCP server Prospeo gets you to 2,000 verified emails a month for $49, tied with Hunter for the cheapest 2,000-email plan here on monthly billing, and unlike Hunter its unused credits roll into the next cycle rather than expiring. The trade is the shape of the product: email and phone, priced per user, and a mobile number costs ten times what an email does. - 1 credit per verified email, 10 per direct mobile - Unused credits roll over and stack on the next cycle's pack - Annual billing delivers the full year of credits upfront From $49 /mo [Read the review of the Prospeo API](https://frontal.so/gtm-apis/enrichment-apis/prospeo-api-review) [site for Prospeo (opens in a new tab)](https://go.frontal.so/prospeo) ### [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/) ### [FullEnrich](https://frontal.so/gtm-apis/enrichment-apis/fullenrich-api-review) Best waterfall without Clay Motion Enrich Verify Model MCP server FullEnrich runs the same waterfall logic Clay does, but as a single API call with a single bill. If all you need is the waterfall and not the spreadsheet around it, this is that half of the trade on its own. - Work email 1 credit, personal email 3, mobile 10 - Profile and company data free with any enrichment, 0.25 a credit on its own - Landline results cost nothing, so you only pay for mobiles From $29 /mo [Read the review of the FullEnrich API](https://frontal.so/gtm-apis/enrichment-apis/fullenrich-api-review) [site for FullEnrich (opens in a new tab)](https://www.fullenrich.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/) ### [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.

Each of those removes providers from the list, and a mobile changes the price by five to ten times the email rate. 02 ### What the license lets you do Internal outbound is covered almost everywhere. Showing the data to your own customers, or reselling it, is a short list led by People Data Labs, and the rest of the reviews say so where they say anything. 03 ### How the person was found A database answers fast and ages between refreshes; a real-time finder like Dropcontact is current and needs a company to work from; a waterfall buys coverage at the price of every provider tried. 04 ### What a miss and a search cost On a hard segment half the lookups come back empty. A provider that charges only on success, and searches for free, can cost less than a cheaper per-record rate that bills every attempt.

FAQ ## People data APIs, answered **How many people data APIs are in this directory?** 17, 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 people 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 people data API is cheapest?** Of the 7 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 people data APIs billed?** 14 of the 17 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, Prospeo, Hunter, FullEnrich, Cognism, Lusha, ZoomInfo, RocketReach, PhantomBuster, Reverse Contact, Crustdata and Dropcontact. The ones the directory reviews live on the MCP page with the connect details. **Is a people data API the same as People Data Labs?** No. People Data Labs is one provider of person data, and its name is close to the generic phrase, which is why the two get confused in search. This page lists every provider in the directory that returns a person record, People Data Labs among them, and its own review covers its license and pricing in full. **Which people data APIs return personal emails?** Clay, People Data Labs, FullEnrich, RocketReach, Wiza, Reverse Contact and Crustdata carry personal email in their records. Most price it above a work email: FullEnrich charges 3 credits against 1. **Can I resell data from a people data API?** Not on standard terms. People Data Labs' standard agreement lets you show its data to your own customers inside your product, but forbids reselling it or giving your users programmatic access to a substantial part of it. Apollo and FullEnrich sell an embedded right under a separate reseller agreement, and Findymail through its credit-based plans. For every other provider, assume the data is for your own use and ask before building a product on it. **What is the difference between people search and person enrichment?** Search returns people who match criteria; enrichment fills in contact fields for one person you already know. They are metered separately: Apollo and ZoomInfo charge nothing to search and a credit to enrich, and LeadMagic's search is free in the app and unmetered on its API from Professional, at 1 credit a result below that.
