How do I get UFC closing odds and line movement?
Request the bout's odds from the MMA Fight Data API, api.fight_odds(fight_id) in Python. It returns one UFCalendar consensus line, the mean across the sportsbooks we track: the opening line, the closing line at the start of the event, the latest point, the movement between them and how many sportsbooks backed each point. Every plan gets these lines; the full movement series is on Pro and Business. Information only, not betting advice.
Free plan: 1,000 requests a month, no card. Paid plans from $19/mo.
Endpoints used
| Method & path | What it returns | Plan |
|---|---|---|
GET /v1/fights/{id}/odds | One bout's consensus moneyline: American and decimal prices, implied and de-vigged probabilities, the opening and closing line and the movement between them. | All plans |
GET /v1/events/{slug}/odds | The consensus line for every bout on a card in one call, in card order, unpriced bouts included. | All plans |
GET /v1/fights/{id}/odds/history | Every movement point of a bout's consensus line, oldest first, with the number of sportsbooks behind each point. | Pro and up |
POST /v1/webhook-endpoints | A signed odds.moved delivery when a bout's consensus line moves 5 points of implied probability or the favourite flips. | Pro and up |
The code
curl and Python read one bout's opening and closing line, then the first points of its movement series; the JavaScript block prints the closing line of every bout on a card.
Every block runs as shown with your API key in the UFCAL_API_KEY environment variable. Python uses pip install ufcalendar and JavaScript or TypeScript uses npm install @ufcalendar/sdk; any HTTP client works too.

}Notes and pitfalls
- One line per bout, never a single sportsbook's: the mean across the sportsbooks we track, with prediction markets and exchanges left out. sources counts the books behind a point, and no book is named.
- opening is the first point recorded, closing the last point at or before the event start (settled bouts only) and consensus the latest. Each side carries American and decimal prices and an implied probability; fair_probability_a removes the margin.
- movement.delta_points_a is the shift from the opening line to the latest point, in implied-probability points on fighter_a, and direction names the side it moved toward. A new point is stored only when the line moves.
- The movement series and the odds.moved webhook need Pro or Business; lower plans get 403 tier_required. An unpriced bout still appears, with null lines and points at 0.
