API and health endpoint monitoring

How it works

1. You define the request: method, URL, headers such as an Authorization header and, for POST, PUT or PATCH, a body.
2. FastPing checks the status code, parses the JSON response and reads the value at a path such as checks.database.
3. If the value differs from the one you expect, or the response is not JSON, the check fails.
4. Two failures in a row open an incident and alert every attached channel.

What FastPing checks

• Status code

  Any 2xx or 3xx by default, or the exact codes your API should return.

• JSON values

  Compare the value at a dot-separated path, such as status or regions.0.healthy, with the expected value.

• Response time

  Warn when the time to first byte exceeds your threshold, before clients start timing out.

• TLS

  Strict certificate validation, including the full chain.
