Tennis Total Sets API
The total_sets board is not posted right now. This page keeps the last measured window — 626settled 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 sets is
Over/Under on sets played. In a best-of-three that is a two-way question about whether the match goes the distance.
How we settle it. Graded against the number of sets completed 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 sets
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 sets 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 42% of 224 decided total sets lines (94 over, 130 under). Computed from the settled rows themselves, scoped to Tennis only.
Read off 313 Over legs out of 626 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.
