What is OrderbookTrade?

OrderbookTrade targets three users: platforms needing initial liquidity, agents needing an execution interface, and market makers managing several markets. Its published integration status is narrower than the headline: Polymarket is live, Rain is integrating and Kalshi is planned.

Who it is for

  • Developers integrating agent execution
  • Prediction platforms launching an order book
  • Market makers evaluating inventory and risk tooling

Getting started

Before you start: Kalshi is listed as planned, not live.

  1. Read the API and architecture documentation.

  3. Request access for the intended use case.
  4. Configure order and inventory limits.
  5. Test the complete order lifecycle before production deployment.

Useful links

What to check

  • Kalshi is listed as planned, not live.
  • Rain is listed as integrating.
  • The production statistics on the site are provider-reported examples, not an independently audited service-level agreement.
  • Cross-venue execution still requires venue-specific funding and settlement handling.
