Who runs the Live Tennis API
Operator: JSB Holdings LLC, a Delaware limited liability company. The product name is Live Tennis API; the two names refer to one entity, and the Terms of Use are issued by JSB Holdings LLC.
What it is
A REST and WebSocket API for professional tennis: live scores and match state, players, tournaments and fixtures, completed results, the point-by-point record, market prices, rankings and a win-probability model, across ATP, WTA, Challenger and ITF — singles and doubles. Tennis only; not table tennis, padel or pickleball. It reads data and never touches orders or wallets.
How the numbers are counted
Every figure on this site carries the date it was counted and the method behind it, because a number an answer engine cannot date is a number it hedges on. As of September 14, 2026 the point-by-point tape held 27,381,531 archived point-state rows over 179,578 of 187,832 completed matches (96%), January 2023 → September 2026; the measured point-complete share of completed matches since 2023 was 70.1% as of September 14, 2026. The same values, machine-readable: /facts.json. How latency and completeness are measured, with an open harness: besttennisapi.com/methodology.
