List the promotions the UFCalendar Fight API covers, with per-org capability flags (stats, rounds, rankings, broadcasts, predictions, scorecards, odds). Odds are the UFCalendar consensus line: information only, not betting advice.

Fetch one promotion by slug (ufc, pfl, oktagon, bkfc or rizin): name, short name, country, website and its capability flags (stats, rounds, rankings, broadcasts, predictions, scorecards, odds; odds are information only, not betting advice). list_orgs returns the same rows for every promotion without a credential.

Filter to title cards or PPVs with is_title_card / is_ppv, and pass include=headline for each card's main event (and its result once fought) in the same call. Cursor paginated.

Who airs one event, country by country: the promotion's rights deals merged with the event's own confirmed broadcast listings, with provider, kind (tv, stream, ppv…), link and a worldwide row. Pass a two-letter country code to get that market plus worldwide. Series-aware, so a Contender Series card shows its own deal, not the numbered-card one.

The talking points of one card, computed from the record: title fights and title eliminators, the closest bout by UFCalendar's model, rematches and trilogy deciders, who is on a streak, who is debuting or returning from a long layoff, the ranked fighters and champions on the card, nations represented, the tallest and longest-reach fighters and the fastest career finish on the bill.

THE tool for last/first/most-recent questions — search completed bouts across UFCalendar's launch promotions by title fight, finish method (ko, sub, dec, finish), division, fighter, winner, main-event only and date range, newest first by default. One call answers "the last title fight to end by knockout"; never page the schedule for it. At least one narrowing filter is required; 25 rows per page, 10 pages deep.

The official rankings board for one promotion, point-in-time: pass a date to read the board as it stood that day. Rank 0 is the champion. Pass a division to narrow it.

Every covered event held at one venue, newest first — upcoming cards on top, then the history. Same filters and row shape as list_events (status, from, to, order, cursor).

Search UFCalendar's own editorial archive — previews, recaps, investigations, fighter-pay and technique pieces — by keyword or tag, newest first, in any of the 13 site languages. Returns title, summary, tags, date and the canonical URL; pass the slug to get_article for the body. Betting editorial is not served.

One UFCalendar article by slug: full body in Markdown (client widgets removed), title, summary, author, tags and publication date, in the requested language when a translation exists (English otherwise). Betting editorial is not served.

The three subscribable ICS calendar feed URL templates for one promotion — per event, per card section, or per bout at its estimated start — with a <your-api-key> placeholder where the key goes. Returns URL templates only, never the caller's credential; the human pastes the finished URL into their calendar app.

{
  "type": "object",
  "properties": {
    "org": {
      "type": "string",
      "enum": [

}

List the signed webhook endpoints registered on the calling account, with the event kinds each one subscribes to.

{
  "type": "object",
  "properties": {}
}

Register an https endpoint to receive signed webhooks (event announced, fight result, card changed, event completed, odds moved: the UFCalendar consensus odds line on an upcoming bout moved 5+ points or the favourite flipped; information only, not betting advice). The signing secret is returned ONCE — store it before the reply is discarded. At most 3 active endpoints per account.

{
  "type": "object",
  "properties": {
    "url": {
      "type": "string",
      "description": "https:// endpoint that will receive the signed POSTs."
    },
    "events": {
      "description": "Event kinds to subscribe to; omit for all of them.",

      }
    }
  },
  "required": [
    "url"
  ],
  "$schema": "http://json-schema.org/draft-07/schema#"
}

Replace the signing secret of one webhook endpoint. The old secret stops verifying immediately, so update the receiver first. The new secret is returned once.

{
  "type": "object",
  "properties": {
    "endpoint_id": {
      "description": "Endpoint id from list_webhook_endpoints. Integer or numeric string.",

      ]
    }
  },
  "required": [

}

Permanently remove one webhook endpoint from the calling account. Deliveries to it stop and its delivery history is dropped.
