The independent, vendor-neutral cross-exchange prediction-market API. Not owned by any exchange.
See pricing — Free demo available TickVault dataThe Dome gap
Dome — the only independent cross-platform prediction-market API (unified Polymarket + Kalshi) — was acquired by Polymarket in early 2026. The neutral lane is now uncontested. TradeHouse fills it: independent, not owned by any exchange.
Unified feed
One API call returns normalized markets from Polymarket, Kalshi, Limitless, and Thales — same schema, same auth.
No EIP-712 juggling
We abstract Polymarket's EIP-712 wallet auth and Kalshi's RSA-PSS 30-min tokens. Your client speaks plain JWT + HTTPS.
Price archive
100k+ historical market archive for backtesting and research — our F1198 corpus continuously updated.
Vendor-neutral
We're not owned by Polymarket, Kalshi, or any exchange. No conflict of interest. Your API call returns the best price across venues.
Pricing
Flat per-account. No per-call metering surprises.
