Get a free API key

Enter your email address and we'll send you a link to your key. Keys are free and allow 60 requests a minute. Lost a key? Ask again: the new key replaces the old one.

Sign-up opens when the public API goes live.

Once you have a key

  1. Send it in the X-API-Key header with every request.
  2. Keep it out of code that runs in browsers or apps, where anyone could read it: call the API from your server.
  3. Read getting started for a first request, and attribution for what to show alongside the data.
