Live, without the plumbing

GET /tennis/matches/live returns every in-progress match with its scoreboard. Drill into one match for sets, games, and serve state. When you need push instead of poll, WebSocket subscriptions and webhooks (match start, set won, final result) deliver events to you — with delivery-proof records, so a missed event is visible instead of mysterious.

Scores mean more with history attached

The same key that streams the live scoreboard answers 'what's the head-to-head?' and 'how has she done on hard courts this year?' in one extra call. That's the difference between a score ticker and a second-screen product.

Results feeds made trivial

GET /tennis/matches/recent gives you the latest completed matches per tour — a results page, a notification trigger, or a data-warehouse sync, straight off one endpoint.
