Your API key, in seconds

One email field, one captcha, no card. The key works immediately against every endpoint.

  • 100 credits every month — resets on the 1st, UTC. Cached lookups cost nothing.
  • All the data — Domain Rating, both traffic estimates, keywords, SERP, index and favicon endpoints.
  • 30 requests / minute — plenty to build and demo with; paid plans raise it to 600.
  • Shown once — we store only a hash of your key. Copy it when it appears.
