  title: Enrich Account Email Verification API
  description: 'Enrich (enrich.so) is a person and company data enrichment API. From one REST interface it resolves professional profiles from an email address (reverse email lookup), finds and verifies professional email addresses, finds phone/mobile numbers, resolves a company and geolocation from an IP address, scrapes LinkedIn company followers, and searches a lead-finder database of people and organizations. All requests use the base URL https://dev.enrich.so/api/v3 and authenticate with an API key passed either in the `x-api-key` header or as `Authorization: Bearer`. Usage is metered against a prepaid credit balance; "not found" results are refunded.

    Grounding note: the single-lookup endpoints in this document (POST /reverse-lookup/lookup, POST /email-finder, POST /email-validation, GET /reverse-lookup/phones, POST /ip-to-company, POST /company-follower, POST /lead-finder/search, POST /lead-finder/reveal) and their credit costs are confirmed from the live Enrich documentation. The batch / progress / results sub-paths are modeled from the documented batch-and-poll pattern (submit -> check progress -> get results) and their exact URL segments should be confirmed against the current docs before code generation. Modeled operations are marked with `x-endpoint-modeled: true`.'
