Enrich (enrich.so), operated by Enrich Labs, is a person and company data enrichment API for B2B go-to-market, sales, and web intelligence teams. From a single REST interface at https://dev.enrich.so/api/v3 it resolves a professional profile from an email address (reverse email lookup), finds and verifies professional email addresses, finds mobile and phone numbers, resolves a company and geolocation from an IP address, searches a lead-finder database of people and organizations, finds employees at a company, and scrapes LinkedIn company followers. Fifty-one operations across nine products, every one of them metered against a single prepaid credit balance and refunded when a lookup finds nothing. Every bulk product follows one submit/poll/results shape with reserve-and-settle billing, ten typed webhook callbacks, RFC 9457 problem details on every error, and official TypeScript and Go SDKs. Enrich also operates a first-party remote MCP server at mcp.enrich.so with OAuth 2.0 and dynamic client registration.
