Hunter
Hunter finds and verifies professional email addresses tied to a domain or person — domain search, single email finder, a bulk-capable verifier, and person/company enrichment across 100+ attributes — behind one `api_key`-gated REST API returning JSON. Searches and verifications draw from a shared credit pool: a free plan covers 50 credits/month, with paid plans starting at $49/month (2,000 credits, 30% off billed annually) up to a custom Enterprise tier.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
