Smarkets odds API
Smarkets is a betting exchange / prediction market in United Kingdom. PropLine pulls its odds into one REST API for 20 competitions (MLB, NBA, NHL, Tennis and 16 soccer leagues). Prices are pregame only: we stop polling a game once it starts. Filter to this book with bookmakers=smarkets.
No credit card. 1,000 requests / day on the free tier.
What we carry from Smarkets
Sports
Soccer leagues
This list is generated from the sports we poll Smarkets for. A competition only returns Smarkets odds while the book has a board up for it, so an off-season league comes back empty.
