What BKFC data does the API include?

Every BKFC event back to the 2018 debut with full cards and results, per-round punch statistics for most of the catalog, fighter records and bios, plus official BKFC rankings and champions.

Is there any other BKFC API?

No mainstream sports-data API covers bare-knuckle boxing. UFCalendar tracks BKFC natively · the same live-results pipeline that covers UFC runs on every BKFC event.

Does one key cover BKFC, UFC, PFL and OKTAGON?

Yes · every plan includes all four launch organizations under one key and one schema; bare-knuckle bouts are distinguished by the sport field.

Is this affiliated with BKFC?

No. UFCalendar is an independent publication; BKFC data is reconciled from public sources and normalized into our schema.

The only bare-knuckle data API

No mainstream sports-data API covers BKFC. UFCalendar tracks it natively: full cards, live results and per-round punch logging from the promotion's own stats feed, normalized into the same schema as our MMA coverage · every bout tagged sport: bare-knuckle-boxing.

Punch stats MMA APIs don't have

Every logged BKFC round carries punches landed and thrown split by target (head/body) and position (distance/clinch), plus knockdowns · per corner, per round, with bout totals. Official BKFC rankings ship alongside: champions, interim champions and the top 8 in every division, Ironweight included.
