Tennis Total Tiebreaks API
The total_tiebreaks board is not posted right now. This page keeps the last measured window — 428settled 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 total tiebreaks is
Over/Under on tiebreaks. A serve-dominance market: it prices two players holding, not two players playing well.
How we settle it. Graded against the number of tiebreaks played in the match.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 16 August 2026.
Books that last posted Tennis total tiebreaks
Measured on the last slate that carried it, 16 August 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 total tiebreaks 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.

Over/Under split, last posted window
The Over won 28.9% of 149 decided total tiebreaks lines (43 over, 106 under). Computed from the settled rows themselves, scoped to Tennis only.
Read off 214 Over legs out of 428 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 Hayato Matsuoka @ Aziz Dougaz 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.

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