Circa odds API

Circa Sports lines and limits as JSON on the same fixture as all 46 books. Mains, alternates and player props, one key, one request.

The Circa odds API from OddsLink returns Circa Sports pre-match lines as clean JSON: moneylines, spreads, totals with Circa's posted limit on each, alternate lines and player props. Add the bookmaker key circa to any odds request.

Circa's numbers sit under the same fixture id as every other book, so you can set the Las Vegas line next to Pinnacle, DraftKings, FanDuel and the rest of the 46 books in one call. Start on the free plan.

More than the main line

Moneyline, spread, total

Football, basketball, hockey, baseball, soccer and MMA, priced the way Circa posts them.

Alternate lines

Circa's alternate spreads and totals, with the main line marked main: true.

NFL player props
