TradeHouse ยท Guide
Unified prediction market API
A unified API normalises markets, prices and identifiers across venues so the same code works for each. The hard part is matching equivalent markets.
- One market and outcome schema.
- Cross-venue identifiers for the same event.
- Consistent timestamps and price units.
- Clear notes where venues differ (fees, settlement).
