BetChecker API
Grade any bet. Audit any tout. From your code.
The same non-affiliate engine behind BetChecker, as a REST API and an MCP server for AI agents. Grade a price A–F against the sharpest market’s de-vigged fair price, audit a tout’s closing-line value, or pull today’s best-graded board. You sell nothing; neither do we.

The tools
grade_bet — grade a price A–F vs the de-vigged fair price. audit_tout — a tout’s CLV record. best_prices — today’s best-graded board. Add the MCP server to Claude, Cursor or any agent, or call the REST API directly. Only grade_bet counts against your plan; audits and board reads are unmetered.
A grade rates the price, not the outcome. We take no bets, sell no picks, and earn nothing when anyone bets — which is exactly why the data is worth trusting.
