Enrich

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.

Enrich publishes 10 APIs on the APIs.io network, including Account API, Company Intelligence API, Email Finder API, and 7 more. Tagged areas include Data Enrichment, Contact Discovery, Web Intelligence, B2B Data, and Lead Enrichment.

The Enrich catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Enrich’s developer surface includes authentication, documentation, engineering blog, changelog, API reference, getting-started guide, pricing, and 30 more developer resources.
