NegativeEV bet checker

- There is NO autonomous agent registration: no dynamic client registration, noclient_credentialsgrant, and no API keys. A register endpoint does not exist — don't look for one.
- An agent acts on behalf of a signed-in user: drive the site in the user's browser session, or send the user's Supabase access token asAuthorization: Beareron requests (including MCP tool calls).
- Anonymous access also works; the free daily quota is metered per device.

Tools:check_bet(grade a bet from text — spends one of the caller's checks when it fully grades),get_slate(is there a checkable slate right now — free),get_usage(checks remaining — free). Anonymous tool calls get their own per-device allowance of 100 checks a day — a separate counter from the web app's 10, so agent traffic never eats a browser's free checks. Send a Supabase access token asAuthorization: Beareron the POST for unlimited checks (paced at 1000 an hour).

Prompts a user can give any MCP-connected assistant to exercise the tools:

- "Is Shohei Ohtani over 1.5 total bases at -120 a good bet tonight?" —check_betgrades it against thousands of simulated games and returns the true probability, the implied probability from the price, and the edge.
- "Is there a checkable MLB slate tonight?" —get_slateanswers per live sport, free, before any check is spent.
- "How many bet checks do I have left today?" —get_usagereports the remaining quota and when the next check frees up.
- "Here's my parlay: Ohtani over 0.5 home runs +280 and Dodgers moneyline -150. Worth it?" —check_betprices each leg and the combined parlay.

Same-origin JSON, quota- and rate-limited, not yet documented as a stable public API (shapes can change without notice):

- GET /slate— is there a checkable slate right now?
- POST /extract— parse a bet from text:{"text": "<bet text>"}
- POST /check— grade the parsed legs (send the fields/extractreturned)
- GET /usage— checks remaining for the caller

A refused request (quota, rate limit, started game) returns an explanatory JSON error. Discovery: /.well-known/api-catalog, /sitemap.xml, and the agent-skills index at /.well-known/agent-skills/index.json
