Coverage & updates

GET /tennis/coverage answers this live from the database, so the numbers below are what the API itself reports.

What is covered

ATP and WTA tour singles, Grand Slams and Challengers, with history back to 1968 (ATP records reach back further, to 1877).
ITF World Tennis Tour singles: men's M15 and M25, women's W15 to W100, under tour ATP and WTA.
Junior events, from the ITF and junior-slam feeds.
Live scores for tour, Challenger and ITF matches; doubles appear live only.
Weekly ATP and WTA singles rankings with point-in-time history, so you can ask where a player was ranked the week a match was played.
Not offered: bookmaker odds (pair the API with a licensed odds provider), college tennis, historical doubles.

Data quality

An automated monitor runs continuously over the data: every result must have two different players, a complete score for its outcome (a retirement is marked as one), and a winner consistent with the sets. ITF matches are checked against the ITF's own published draws and retirements against an independent results source; a proven correction is applied and journaled, and a row nothing can prove stays as it is rather than being guessed.
