Odds API by market / UFC
UFC Round Betting API
The round_betting board is not posted right now. This page keeps the last measured window — 571 settled 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 round betting is
A named fighter to win in a named round. The longest prices on a card, and the market with the most outcomes per fight.
How we settle it. Graded from the official winner and the round the fight ended in. Both have to match.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 5 October 2026.
Books that last posted UFC round betting
Measured on the last slate that carried it, 5 October 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 round betting 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.
571 round betting outcomes settled in the last 4-day window it was posted across 4 books. The 12 most recent:

Hit rate, last posted window
11% of 472 settled round betting legs hit (52 yes, 420 no). Counted on the YES side only — books that price this two-way contribute their Over leg, not both. That is the base rate across the whole priced field, not a per-player figure.
Read off 472 YES legs out of 571 settled outcomes on this market. The rest are the Under side from books that price it two-way, which answers a different question.
Per-player hit rates and L5 / L10 / L20 splits live on /trends.
Live response
Captured from the real endpoint on Nell Ariano @ Preston Lagrange 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.

}The response shape is the-odds-api compatible — events, bookmakers, markets, outcomes — so migrating is usually a base URL change.
