Public Free API

RiskAPI Utility Surface

A small collection of fast, deterministic API utilities for straightforward text, time, and hashing tasks. The current public surface focuses on simple free endpoints that are easy to test and integrate.

Open API reference

Browse the reference, copy an endpoint, and start with a direct request. Responses are JSON, the routes are rate limited, and the public free endpoints are intended to stay lightweight and predictable.

Free checks

These public endpoints are intended to be simple, predictable, and easy to verify from a browser, terminal, or application client.
