Betting Exchange API FAQs

Exchange filters, order books, streaming and market-data limits.

What does the betting exchange API include?

It provides dedicated pre-match exchange order books with back and lay price ladders, available size, best prices, last traded price and matched activity where supplied.

Which betting exchanges can I filter?

The exchange endpoints accept Betfair, Smarkets, Matchbook and Betdaq through the exact exchanges=betfair, exchanges=smarkets, exchanges=matchbook and exchanges=betdaq filter values.

Does odds-api place or manage bets?

No. odds-api provides market data only. It does not place, manage, settle or authorize wagers through an exchange account.

How do I retrieve back and lay prices?

Find the event ID, then request its exchange order-book snapshot with the exchanges filter and your required ladder depth. Each selection can include available_to_back and available_to_lay arrays.

Can I stream betting exchange price changes?

Yes. Start with the REST snapshot, then use its resume token with the matching SSE or WebSocket endpoint. Reload the snapshot whenever the stream sends a resync event.
