What is a company enrichment API?

A company enrichment API takes one identifier for a business, a domain, a company URL or slug, an internal ID or a social handle, and returns a structured firmographic record: industry, headcount and growth, locations, founding year, funding history, investors and hiring activity.

DataForB2B resolves any of those identifiers against 75M+ companies and returns the full record for a flat 1.5 credits per call, funding rounds and investors included.

  • Domain enrichment on lists runs through Company Search with the domain column: 0.75 credit per cached result, up to 1000 records per request.
  • Available over REST and as the enrich_company tool in the MCP server.
  • Monitors push funding, hiring and growth events for enriched companies to your webhook.

Pass the company's universal slug, its full or short company URL, its encoded org_ ID or an X handle. You get the complete firmographic record in one call.

MCP

Native tools for agents.

Drop our MCP server into Claude, Cursor, or any agent runtime. The model picks the tool, builds the filters and reads the response — no glue code, no schemas to maintain.

Questions from enrichment builders.

Anything we missed? Talk to us.

Yes. /enrich/company takes a slug, a company URL, an encoded org_ ID or an X handle. For a raw domain, call /search/companies with a domain = condition (or domain in [...] for a list), the result carries name, industry, employee count, location, growth and funding fields for 0.75 credit on cached data, and returns the org_ ID you can pass to /enrich/company when you need the round-by-round funding history and investors.

A flat 1.5 credits per enriched company, whatever the size of the record, funding history, investors, offices and growth included. Domain lookups through Company Search cost 0.75 credit per result with enrich_live: false, or 1.5 credits with live enrichment.

Enrichment does not guess from a free-text name. Use an unambiguous identifier, the slug, the company URL or the org_ ID, or resolve the name first with Company Search (name = or keyword like plus a country filter) and enrich the ID you pick. That keeps ten companies called “Cresta” from colliding.

Headcount growth in percent over the last 1, 6 and 12 months, the number of recent hires, the count of active job postings and the follower count. Combined with the funding block they are the inputs most scoring models use to rank accounts that are scaling.

Yes. Create a monitor with a signal (funding, job change, founder move, post engagement), a watch target and your webhook URL. DataForB2B POSTs the event to your endpoint with a signed payload and exponential retries, so your agent reacts to a new round or a hiring spike instead of re-polling the enrichment endpoint.

Yes. The DataForB2B MCP server exposes enrich_company next to search_company, search_people and enrich_profile. Claude, Cursor or any MCP-compatible agent can call it with a slug, URL or handle and read the structured company record directly.
