Live Tennis API
Real-time tennis ground truth via API
API · Python · MCP
Live Tennis API streams live tennis match state as structured JSON over REST and WebSocket — sub-second scores with sets, games, points, who's serving, a break-point flag, and retirement/walkover status. It's the same kind of ground-truth result data used to resolve tennis contracts on Polymarket and Kalshi.
Coverage spans ATP, WTA, Challenger, and ITF, singles and doubles, from one arbitrated feed. Beyond live scores: historical results back to 1968 (171k+ matches point-by-point since 2023), match-winner market prices, an AI win-probability model, and shot-by-shot rally data for 11k+ charted matches.
For builders, an MIT-licensed observe-only toolkit pairs the feed against Polymarket's Gamma tennis markets, and an MCP server on the official MCP Registry gives AI agents 12 read-only research tools. The free tier includes live scores with no card required.
