UFC Win by Knockout API
The player_knockout_win board is not posted right now. This page keeps the last measured window — 32settled 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 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 16 August 2026.
Books that last posted UFC win by knockout
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 UFC win by knockout 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 31.3% of 16 decided win by knockout lines (5 over, 11 under). Computed from the settled rows themselves, scoped to UFC only.
Read off 16 Over legs out of 32 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 Joel Alvarez @ Chidi Njokuani 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.
