FullHunt

Verified Jul 2026

FullHunt maintains a searchable database of attack-surface data for the internet, combining subdomain enumeration, exposed-service discovery, and continuous monitoring for domains registered on the platform. Every endpoint — search, host lookups, domain enrichment, scan triggers — draws from the same per-request credit pool, from a free-forever tier up through paid Builder and Scale plans. Authentication is a single account-scoped API key sent as a header on every request.

  2. Send it on every request as a headerAuthorization: <key>
  3. The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored
