Live sports market data API

Every market. Every tick. Pushed live.

Load sports, tournaments, events, and markets over REST. Then keep one socket open and every marketRate change lands in your app the moment it happens.

Product

From sport list to live price.

REST gives you the snapshot. The socket gives you the stream. IDs stay linked the whole way down.

One clean path for your catalog.

Sport list, tournament list, and event list give you stable ids. Pass them to market list and market details — no guessing, no remapping.
