This host serves agents that need pre-trade analysis on Polymarket binary markets. It covers two complementary read-only operations: assessing whether a market's order book is healthy enough to trade (spread, depth, stale/crossed status) and estimating the cost and share yield of a hypothetical BUY order given a USD budget. It does not execute trades, support SELL-side quoting, or provide streaming data.

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.
Make my x402 API at https://bookproof-api.sn95wjq846.chatgpt.site 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://bookproof-api.sn95wjq846.chatgpt.site --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.
