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, across ATP, WTA, Challenger and ITF, singles and doubles. It serves live scores and match state, players, tournaments and fixtures, completed results and the point-by-point record. It also serves market prices, rankings and a win-probability model. 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. A number an answer engine cannot date is a number it hedges on. As of October 15, 2026 the point-by-point tape held 29,729,800 archived point-state rows. That is 191,724 of 202,280 completed matches (95%), January 2023 → October 2026. The measured point-complete share of completed matches since 2023 was 58.6% as of October 15, 2026. The same values, machine-readable: /facts.json. How latency and completeness are measured, with the open-source test tool: besttennisapi.com/methodology.
