People Search API
for AI agents.
Search 850M+ B2B profiles with 60+ filters, in plain English or JSON. Every profile refreshed every 30 days.
What is a people search API?
A people search API takes a description of the people you want, expressed as filters on title, company, seniority, skills, location or career history, and returns the matching professional profiles as structured JSON. It is how an AI agent, a sales tool or a recruiting product finds people it does not know yet, instead of enriching a list someone already built.

Search finds people you do not know yet: you pass filters and get back every profile that matches. Enrichment starts from one person you already have, a profile URL or an ID, and returns the full record plus contact data. They chain: People Search returns encoded IDs, People Enrichment resolves each one.
One that the agent can query at runtime with structured filters, not a CSV exported once a quarter. DataForB2B exposes People Search as a REST endpoint and as the search_people tool in its MCP server, so an AI SDR can turn an ICP into filters, pull fresh matches, and enrich only the leads it decides to contact.
Yes. Career history is filterable, not only the current job: past_company and past_title find alumni of a company or people who held a role before, and school, degree and years of experience narrow the pool. That is how recruiters map talent at competitors and how VCs find operators who could become founders.
The index refreshes continuously from public sources, so a search reflects role changes as they become public rather than a quarterly snapshot. You can return cached records for large lists, or request live data on the results that matter most.
Yes. The DataForB2B MCP server exposes search_people as a tool next to search_company, enrich_profile and the other endpoints. Claude, Cursor, OpenAI-based agents or any MCP runtime can read the tool definition, build the filters from a plain-English request and parse the structured response, with no glue code.
