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 — 102settled 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 16 August 2026.

Books that last posted UFC round betting

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 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.

102 round betting outcomes settled in the last 4-day window it was posted across 2 books. The 12 most recent:

Hit rate, last posted window

7.8% of 102 settled round betting legs hit (8 yes, 94no). 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.

Per-player hit rates and L5 / L10 / L20 splits live on /trends.

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.

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

Try it

1. List UFC events to get an event id:

curl "https://api.prop-line.com/v1/sports/mma_ufc/events?apiKey=YOUR_API_KEY"

2. Pull round betting for one game across every book — swap in a live event id from step 1 once books post it again:

curl "https://api.prop-line.com/v1/sports/mma_ufc/events/117236/odds?apiKey=YOUR_API_KEY&markets=round_betting"

3. After the game, get the graded outcomes with the actual stat:

curl "https://api.prop-line.com/v1/sports/mma_ufc/events/117236/results?apiKey=YOUR_API_KEY"

Steps 1 and 2 run on the free tier. Step 3 — prop resolution — starts on Hobby at $9/mo. See pricing.
