Try the API. Right now.
One call in, one decision out. Send an email and an IP, get back a risk score, an allow / challenge / block recommendation, 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.
Scenarios
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.
Want to see Fidro remember?
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.
// Press "Send request" or run the curl. // The JSON that lands here is exactly what // your code would receive in production.
That is the whole integration.
One POST at signup, login, or checkout, and you act on recommendation instead of writing your own scoring. A free key gives you 200 real validations a month, plus test keys that behave exactly like this sandbox.
No credit card. 200 validations/month free.
