How keys work here

  • Your key is a signed token, not a database row. It carries its own label and tier, and the server verifies it with a secret rather than looking it up. That is what lets this run with no user table and no sign-up.
  • It is shown once. Nothing stores it, so nothing can email it back to you. Lost keys are replaced, not recovered.
  • Keep it server-side. Anyone who reads your key can spend your rate limit. For a website, proxy calls through your own backend rather than shipping the key to the browser.
  • Free tier is 60 requests a minute. Responses are cached for 60 seconds at the edge, so polling faster than that mostly returns the same numbers anyway.
