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 15 September 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.

SleeperUnderdog Fantasy

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.

64 fight time outcomes settled in the last 4 days across 4 books. The 12 most recent:

Over/Under split, last 4 days

The Over won 82.9% of 35 decided fight time lines (29 over, 6 under). Computed from the settled rows themselves, scoped to UFC only.

Read off 35 Over legs out of 64 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 Michael Aswell @ Joo Sang Yoo, 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.
