Guides for Hunter.io

Step-by-step setup for the most popular AI clients.

Setting up Hunter.io

From the connector definition itself: where to find the credentials, what they need to be allowed to do, and which API this adapter talks to.

This connector uses the Hunter.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).

Confidence scores: every email returned has a confidence 0-100 — Hunter's estimate of deliverability. >90 = reliable, 50-90 = use with care, <50 = high bounce risk.

Verifier vs Finder:

  • email_verifier: 'is this email deliverable?' — returns status (valid/invalid/accept_all/disposable/webmail/unknown).
  • email_finder: 'find the email for this person at this company' — returns the most-likely email pattern with confidence.

Out of scope here: Hunter Campaigns (their cold-email product), Leads (CRM-lite), webhooks.
