OddsRelay

OddsRelay is an odds-data API for businesses. It serves odds from 140+ bookmakers, 60+ of them live in the UK & Ireland through one keyed REST API, as two co-equal products: each bookmaker's raw prices, and matched feeds where every bookmaker back price is already paired with the best lay price on Betfair, Smarkets, Matchbook and BETDAQ and the liquidity available at that lay (six feed types: Standard, Each-way, Extra place, Best odds guaranteed (BOG), Dutching and 2Up). bet365 is included in every plan.

It is the data behind oddsmatchers, arbitrage and value tools, trading tools, and tipster and comparison sites. The feed applies no ratings.

Every product on sale meets a maximum update time of 10–20 s: how old a bookmaker's price can be when it reaches you. Each response carries its own time, so you can check it on your own events.

The feed is pre-match and pull only (no websocket or webhook on self-serve plans), with UK and Irish prices only and no price history or closing prices.

Start on the Free plan: 2,500 tokens a month, no card, for as long as you stay on it. Paid plans from £19 a month, Enterprise from £750 a month. The docs and the OpenAPI contract are public. OddsRelay is a data supplier, not an operator, and takes no bets.
