Third-Party API Contract Drift Monitor

Detect authorized API contract changes with baseline evidence

A privacy-bounded monitor for authorized third-party APIs. Provide an OpenAPI 3 spec URL and a baseline state ID, then run bounded GET checks to detect added, removed, or changed contracts. It records fingerprints, timestamps, status codes, and timeout or rate-limit outcomes without POST requests, login flows, proxy rotation, or response bodies. Built for API teams that need scheduled change evidence before integrations break.

Third-party API contracts can change without notice, and teams need a dated record of what changed before an integration fails. I built this as a narrow, GET-only evidence monitor so teams can check authorized endpoints on a schedule without collecting response bodies or handling credentials.
