Odds API by market / UFC
UFC Total Rounds API
Live total_rounds 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 UFC total rounds is
Over/Under on how long the fight lasts, quoted in rounds. Books post it at half-round lines so a finish on the buzzer cannot push.
How we settle it. Graded from the official result: completed rounds are the last full round plus the elapsed time of the round the fight ended in.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 30 September 2026.
Books posting UFC total rounds
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 UFC total rounds 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.
415 total rounds outcomes settled in the last 4 days across 11 books. The 12 most recent:

| Over 2.5 | — | void |

Over/Under split, last 4 days
The Over won 58.2% of 165 decided total rounds lines (96 over, 69 under). Computed from the settled rows themselves, scoped to UFC only.
Read off 209 Over legs out of 415 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 Eric Nolan @ Court McGee, 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.
