Ultimate Fighting Calendar
UFCalendar Fight API

The fight database, as an API.

Events, full cards, results, per-fight and per-round statistics, complete fighter careers, official rankings back to 2013, Power Index ratings and AI win probabilities — for UFC, PFL and OKTAGON. The same data that powers this site, served as clean JSON.

Free tier: 500 requests/month, full data, no credit card.

One request, ten years back

The rankings time machine: every official UFC board since 2013, valid until superseded. Rank 0 is the champion.

What no other API has

Three orgs, one schema

UFC, PFL and OKTAGON at launch — every alternative is UFC-only. More orgs join as they clear our reliability bar; /v1/orgs carries per-org capability flags so your client discovers coverage.

Rankings time machine

Official UFC rankings point-in-time back to 2013 (623 snapshots), plus PFL and OKTAGON boards. "What was he ranked that night?" is one query parameter.

Card-change log

Fight added, opponent swapped, card reshuffled — the diff log behind our "card updated" badge is an endpoint, so your app can react to late changes.

Per-round statistics

Strikes by target and position, takedowns, control time — per fight and per round. 10,674 fights carry full stat lines (91% of the catalog).

Complete careers

Fighter timelines span every promotion they ever fought in — not just the launch orgs. 121,078 career rows, merged and deduplicated.

Built for AI agents

OpenAPI 3.1, llms.txt, stable snake_case JSON with a predictable envelope. Point an agent at the spec and it works.

Pricing

Hard caps, no overage bills, cancel anytime. Annual billing gives 2 months free.

Questions

Why only UFC, PFL and OKTAGON?
Those are the orgs where our data is deepest: per-fight statistics, own live results pipelines, official rankings boards. ONE, KSW, RIZIN and ACA are tracked and join the moment they clear our reliability bar — each addition is announced in the changelog.
Do you serve betting odds?
No, by design. The Fight API carries no betting data on any tier.
Can I use the fighter images?
Yes — every image the API returns is Creative-Commons or public-domain licensed from Wikimedia Commons, with artist and license fields included. Displaying that credit is required by the license.
How fresh are results?
Live results land within 5 minutes for every launch org (2 minutes for UFC). Pre-fight card changes refresh every 2 hours, rankings twice a day, model probabilities every 30 minutes.
What are the usage rules?
Paid tiers cover commercial display and analysis. No bulk resale of the raw dataset below Enterprise, and no use as an official-data feed for regulated sportsbooks. Free tier is non-commercial with an attribution link.
