  description: "The API requires a subscription ( from $29.99 per month ). There is no free tier of the API and no trial. Your key is issued in the member area. Send it in a header, over HTTPS: X-API-Key: ct_live_… HTTPS only. A request that arrives over http:// is refused rather than redirected."
  notes:
  - One key per account. Rotate or revoke it in the member area at any time; the old key stops working within about a minute.
  - The OpenAPI also states a ?key= query parameter is accepted, but the docs say to keep the key out of the URL.
  - More than 30 rejected keys in a minute from one address stops that address for ten minutes.

Free tier, no form to fill in. Signing in shares your email address with us — we store it to create your key and to recognise you if you sign in with another provider. See our Privacy Policy and Terms.
