Hunter.io

Find and verify email addresses via Hunter.io. 7 tools for domain search, email finder, email verifier, account stats. Bearer-token / query-key auth.

Setup

io API v2 (hunter.io/api-documentation/v2).

Setup:

  1. Sign in to https://hunter.io → top-right avatar → API → API Keys.
  2. Copy the key. Set HUNTER_API_KEY.

Authentication: query-string ?api_key=... on every call (QUERY_AUTH). Hunter also accepts the API key in an X-API-Key header but query-string is the documented default.

Credits model: every request consumes credits per your plan. domain_search is the most expensive (returns up to 100 emails per call); email_verifier and email_finder are 1 credit each. email_count and account are FREE (don't deduct).
