The API Reference is grouped by the surface that owns each route, so the sidebar reads the way the product is sold.
  • API Reference holds market data, news, trading, and account state. This is the surface your trading front end calls every day.
  • Partner API holds what a firm’s back office calls: trdrs Connect registration handoff and its billing usage, the evaluation accounts your firm issues on the trdrs venue, webhooks, and the preview challenge routes.
  • Models is Scalar’s generated schema index. Every request and response body in the reference links to a named model there.
Quick Start is a guide page, not an API group. It links to these real groups instead of repeating the same endpoints under a second name, so there is exactly one place where each route is documented.
