SharpAPI Documentation

SharpAPI is a real-time sports betting odds aggregation platform that provides:

Real-time Odds - Continuously refreshed odds from major sportsbooks via REST or SSE streaming
Incremental Delta - /odds/delta returns only what changed since your last poll, with removals tracked — no re-downloading the whole board
+EV Detection - Automatic expected value calculation using sharp book references
Arbitrage Alerts - Cross-book arbitrage detection with optimal stake calculations
No-Vig Odds - Fair odds with bookmaker margin removed, using Pinnacle as the sharp reference
Streaming - Server-Sent Events and WebSocket push for odds, opportunities, and game state
Agent-Ready - Built-in MCP server and /llms.txt so AI assistants can discover and query the API without glue code

Staying Current — CheaplyPermalink for this section

Three mechanics keep your view of the market fresh without burning your rate limit:

Measure freshness, don’t assume it. GET /health exposes newest_odds_age_s — the live age of the newest odds in the store, typically single-digit seconds. No key required — check it yourself right now.
Poll incrementally. GET /odds/delta?since=... returns only rows that changed since your watermark, plus a removed list — a delta poll is a few KB where a full snapshot is megabytes.
Or skip polling entirely. SSE and WebSocket streams push odds, opportunity, and game-state updates as they happen (WebSocket add-on).
