Domainsdb.info

Verified Jul 2026

Domainsdb.info indexes registered domain names across gTLDs and ccTLDs for keyword, zone, and registration-date search, aimed at domain-availability and portfolio-monitoring tools. Anonymous access has since been retired: a live GET against `/v1/domains/search` now returns a 401 "API key required" JSON error rather than open results, requiring a signed-up key billed through a prepaid credit balance ($5 per 100,000 credits) instead of the fully keyless lookup it once offered.

Auth quickstart

  1. Sign up with the provider to get an API key.
  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

Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
