Yes. Cito serves the World Extreme Cagefighting archive over REST at https://api.citoapi.com/api/v1/wec: 50 cards, 2001 to 2010, results for every bout, official round-by-round stats (348 of 362 bouts), fighters and head-to-head, in the same shape as the UFC API.

What does the WEC API cover?

50 World Extreme Cagefighting cards from June 2001 to December 2010: 362 bouts with winner, method, round and time, official round-by-round stats on 348 of them, fighter profiles with fight history, career stats and head-to-head.

Do WEC fighters have the same ID as on the UFC API?

Yes, when they have a UFC record: they keep their /ufc/fighters/{slug} slug on /wec (jose-aldo, for example), and ufcFighterSlug marks it on every fighter object.

Can I get a fighter's whole career across promotions?

Their archive career, yes. /mma/fighters/{slug} adds recordByPromotion: the record in PRIDE, Strikeforce, WEC, Bellator and the other archives in one call. For UFC fights, the UFC career endpoint covers the rest.

Which plan includes WEC?

Every UFC plan, with no extra game to add: a free key or a UFC Starter key reads it. Fighters, profiles, fight histories and bout results work on every plan. Like /ufc, cards, bout lists and stats follow the plan's history window (30 days on Free, 90 on Starter), and every WEC card is from 2001 to 2010, so the full archive with official round-by-round stats is on Pro.

Does the WEC API have live data or rankings?

No. It is a closed archive of 2001 to 2010 cards: no live data, rankings or upcoming cards. /wec/events/upcoming always returns an empty list with a note.

Can I use the WEC API with Claude or Cursor?

The next Cito MCP release adds league wec to combat_events, combat_card, combat_bout, combat_athlete and combat_h2h. Until it ships, call the REST endpoints with your key.

Is this an official WEC product?

No. Cito is an independent data API and is not affiliated with World Extreme Cagefighting or its rights holders.

WEC, read like UFC

Cards, results and round stats from WEC's run, in the fields your UFC code already reads.

50 cards, 2001 to 2010

WEC from June 2001 to its last card in December 2010, each card main event first.

Results to the second

Winner, method, round and time for every bout, with finish position, submission and referee.

Official round stats

Strikes, takedowns, knockdowns and control time per corner per round on 348 of 362 bouts.

The /ufc shape

Same field names and "13 of 18" formats as UFC rounds, so one parser reads both promotions.

Same fighter IDs

jose-aldo is the same id on /wec and /ufc; ufcFighterSlug marks every shared fighter.

Whole archive career

/mma/fighters/{slug} adds the record in every archive promotion, WEC included.

How does WEC data connect to the UFC?

WEC merged into the UFC in 2010, so many of its fighters carry on in the UFC data. A WEC fighter with a UFC record keeps the same id on /wec and /ufc: jose-aldo on /wec/fighters/jose-aldo is the fighter on /ufc/fighters/jose-aldo, so their WEC rounds and UFC rounds join without name matching. Aldo's WEC career stats, for example:

GET /api/v1/wec/fighters/jose-aldo/stats	Value
record	8-0-0 (8 fights with stats)
significantStrikes	263 of 500 (52.6%)
leg	70 of 78 (89.7%)
knockdowns	5
takedowns absorbed	1 of 27 (3.7%)

Are WEC stats in the same format as UFC stats?

Yes. A WEC round row has the same fields and formats as a /ufc round row, so a model or stat page built on UFC rounds reads WEC rounds without a new parser. 348 of 362 bouts with official round stats; hasStats on each event and bout says which.

Field	Format
significantStrikes / totalStrikes / takedowns	"landed of attempted", e.g. "13 of 18"
head / body / leg	Significant strikes by target, same format
distance / clinch / ground	Significant strikes by position, same format
knockdowns / submissionAttempts / reversals	Counts
controlTime	"m:ss", e.g. "1:42", or null when not recorded

What is the first WEC endpoint to call?

List the cards that carry stats with /wec/events?hasStats=true, open one with /wec/events/{slug} (for example wec-48), then pull any bout's rounds with /wec/bouts/{boutId}/rounds.
