Tennis Double Faults API
The player_double_faults board is not posted right now. This page keeps the last measured window — 1,613 settled outcomes — and reactivates on its own the first build after books post the market again. The endpoint, the response shape and the free tier work today.
No credit card. 1,000 requests / day on the free tier.
What Tennis double faults is
Double faults by one player. The mirror of the ace market: it is the same second serve priced from the other direction.
How we settle it. Graded against the settled double-fault count. A player who hit none is settled at zero, not voided — an absent figure is a zero, not a missing result.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 25 September 2026.
Books that last posted Tennis double faults
Measured on the last slate that carried it, 25 September 2026. When books post it again, this list rebuilds from whichever ones actually do.
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 double faults 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.

Read off 807 Over legs out of 1,613 settled outcomes on this market. The rest are Unders and milestone legs (“1+”, “2+”) that some books price here too, and a threshold rung is not an Over.
A few days of one market describes a few days — it is not an edge. Pull the full history through /exports/resolved-props for a sample worth modelling on.
Live response
Captured from the real endpoint on Anna Bondar @ Elena-Gabriela Ruse while it was posted, trimmed to one book and three outcomes so the shape stays readable. The full response carries every book and every line, alternates included, in the same call.
Live sample unavailable at build time — the curl below is the call that produces it.
The response shape is the-odds-api compatible — events, bookmakers, markets, outcomes — so migrating is usually a base URL change.
