This host is a thin wrapper over public Lichess API endpoints, serving agents that need chess puzzle content or player profile data. It targets use cases like displaying the daily puzzle, assessing a player's rating across time controls, or pairing puzzle difficulty against a known player's skill level. It does not support game history retrieval, move validation, bulk lookups, or any chess engine interaction.

Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.
- 2 of 4 routes have never been scored — the audition tests them for the first time.
- 2 routes are flagged by the verifier as failing or inconclusive.

Make my x402 API at https://chess402.vercel.app discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://chess402.vercel.app --json`. Heads up: 2 routes have never been scored — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
