Odds API by market / UFC
UFC Win by Knockout API
Live player_knockout_win odds are posted now, across every book that carries it, in one REST call. This market is early in its season — not enough outcomes have settled yet to report results, so the graded-results view here opens on its own once they do. Every outcome settles against the official result when play ends.
No credit card. 1,000 requests / day on the free tier.
What UFC win by knockout is
Will this fighter win by knockout or technical knockout. One-sided per fighter, so a card carries two of them per bout.
How we settle it. Graded from the official winner and method together. A disqualification or an overturned result is not a knockout and settles conservatively.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 1 October 2026.
Books posting UFC win by knockout
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.
Settled UFC win by knockout outcomes — coming after the first games
The board is live now, ahead of its season's first results. Once games play, every outcome is settled against the official result and this section fills with real rows — each a price that was on a board before the event, carrying the actual figure it was graded against. No other odds API returns that last column.
We do not report a hit rate until enough outcomes have settled to mean something — presence now, proof once the results are in. This page fills in that view on its own the first build after enough settlements land.
Live response
Captured from the real endpoint on Ismail Naurdiev @ Marvin Vettori, 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.
