API playground

Try the API. Right now.

One call in, one decision out. Send an email and an IP, and get back a risk score, a recommendation to allow, challenge or block, and every check that fired. Run it below or copy the curl into your terminal. No signup.

Sandbox uses the API's test fixtures, the same deterministic scenarios a test key returns, so you can explore every outcome without real data.

                        Same request shape as the real POST /api/validate. The demo key dies in an hour; a real key works identically, swap the URL for fidro.io/api/validate.

                            This playground has no account, so every call here is stateless. Add "event": "signup" to the same request with a test key and the third signup from one IP inside an hour comes back with ip_signup_burst. The test mode guide has a scenario for each anomaly.
