Odds API by market / Tennis
Tennis Point Spread API
Live spreads odds across every book that posts it, in one REST call — and, unlike any other odds API, every one of those outcomes settled against the official result once play ends.
No credit card. 1,000 requests / day on the free tier.
What Tennis point spread is
The handicap market. Each outcome carries a `point` (the handicap) alongside its price. Alternate spreads arrive in the same response rather than behind a separate paid market, so a full ladder is one request.
How we settle it. Settled against the final margin. An exact push on a whole-number handicap returns `push`, not a win or a loss.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 6 October 2026.
Books posting Tennis point spread
Measured live, not listed from a spec. Coverage moves — a book that has not put its board up yet will not appear until it does, which is exactly what this list is for.
Line shopping across all of them is one request — every book arrives in the same bookmakers array, not one call per book. Add ?bookmakers= to narrow it, or use /best-line for the best price per line already ranked.
Recently settled Tennis point spread outcomes
These are real rows out of the API, not an illustration. Each one was a price on a board before the event and carries the actual figure it was graded against afterwards. No other odds API returns that last column — they stop at the price.

Hit rate, last 4 days
49.8% of 20665 settled point spread legs hit (10293 yes, 10372 no). Counted on the YES side only — books that price this two-way contribute their Over leg, not both. That is the base rate across the whole priced field, not a per-player figure.
Read off 20,665 YES legs out of 20,755 settled outcomes on this market. The rest are the Under side from books that price it two-way, which answers a different question.
Per-player hit rates and L5 / L10 / L20 splits live on /trends.

}The response shape is the-odds-api compatible — events, bookmakers, markets, outcomes — so migrating is usually a base URL change.
