Company enrichment APIs for AI agents

Company enrichment APIs turn a name, a number or a site into a record an agent can file: registry facts, firmographics, or a KYB check. A listing is included when its category is Data, Verification, Finance or Intelligence and its name says company, companies, enrichment or KYB, or its text uses a phrase such as company enrichment, firmographic, Companies House, business registry, company data or company intelligence. The word business on its own is not the rule, so a calendar of business days does not land here. The agent looks the listing up for free and pays the provider per call over x402 in USDC on Base, Solana or Algorand. No API key. Settlement-verified means a paid route with an on-chain receipt. Examples are claimed verified listings. Unclaimed (bazaar) imports are labelled and are not examples. Listing is free and the provider keeps 100% of each settled call. Counts are live for this rule.

25 APIs and 163 endpoints match this page. 25 are settlement-verified: a paid route with an on-chain receipt.
