Tennis Player Aces API
The player_aces board is not posted right now. This page keeps the last measured window — 1,958settled 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 player aces is
Aces served by one player across the match. Surface and format drive it as much as the server does — a five-set major and a three-set tour event are different markets on the same name.
How we settle it. Graded against the settled ace count for that player in that match. A retirement or walkover voids rather than settles.
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 player aces
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 player aces 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 35.3% of 671 decided player aces lines (237 over, 434 under). Computed from the settled rows themselves, scoped to Tennis only.
Read off 979 Over legs out of 1,958 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 Emiliana Arango @ Iga Swiatek 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.
