Odds API by market / UFC
UFC Fight Time API
Live fight_time_minutes 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 fight time is
Over/Under on fight duration in minutes, rather than in rounds. The same question as total rounds asked at finer resolution.
How we settle it. Graded from completed rounds converted to minutes at five minutes a round.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 6 October 2026.
Books posting UFC fight time
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 fight time 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.
94 fight time outcomes settled in the last 4 days across 4 books. The 12 most recent:
| Bet | Actual | Result |
|---|---|---|
| Over 12.5 | — | void |
| Under 12.5 | — | void |
| Over 14.99 | — | void |
| Over 14.5 | — | void |
| Under 14.5 | — | void |
| Over 7.75 | — | void |
| Under 7.75 | — | void |
| Over 24.5 | 25.0 | won |
| Over 12.75 | 2.15 | lost |
| Over 12.75 | 2.15 | lost |
| Over 11.75 | 4.13 | lost |
| Over 6.75 | 15.0 | won |
Over/Under split, last 4 days
The Over won 28.6% of 42 decided fight time lines (12 over, 30 under). Computed from the settled rows themselves, scoped to UFC only.
Read off 52 Over legs out of 94 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 Melissa Gatto @ Ernesta Kareckaite, 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.
