Codeforces vs Mintlify

Codeforces exposes a JSON API over its own contest and user database, covering problems, contests, submissions, ratings, and hacks through methods like contest.standings, user.info, and problemset.problems. Most methods are fully public and callable with no key at all — a live call to user.info returned real rating and rank data with zero authentication — while a handful of privacy-sensitive methods (e.g. user.friends) require a signed apiKey/apiSig pair generated from a registered account. There's no paid tier or usage fee; the service is entirely free.

Mintlify's Admin API lets a documentation project's own backend trigger deployments, kick off AI agent jobs, and pull analytics (page views, search queries, feedback) via bearer-token endpoints prefixed mint_, confirmed live by a real request that returned a clean 401 "Unauthorized" rather than any generic error, with a separate CORS preflight also succeeding. Admin API access itself is gated to Mintlify's paid Pro plan and above — the free Starter tier covers hosting and the docs editor but not the Admin API — per its own current pricing page.
