Live Tennis API — Real-Time Tennis Scores over REST & WebSocket

This is our live board, unedited and uncut, running for fifteen minutes against real matches. Every row is a live match: our score commit on the left, and the market’s line on the right, both stamped with their own clocks. Nothing is sped up, staged or re-ordered.

What you are looking at

The recording has no narration — the audio is a background music bed only, so nothing is spoken that is not also on screen. This section is the text equivalent of what the video shows.

• One lane per live match. Each row carries the current score exactly as our feed publishes it, across ATP, WTA, Challenger and ITF.
• A measured interval, with its sample size. The figure at the top is the time between our score commit and the market’s next quote move, averaged over the number of samples shown beside it.
• Independently checkable. Prices come from the venue’s own public API, not from us, so both halves of the picture can be verified against the source.
