API

This section describes methods for interacting with the Xpress platform. These methods are categorized into three types.

• Contract API: All trades are executed within contracts on Sonic. To set an order, you call the contract entry point.

• The HTTP API allows you to retrieve information about past and current prices, orders, and trades.

• The WebSocket API is used to receive events about recent changes.

Interaction is available on mainnet with:

• two market contracts SUSDC and ETHUSDC​

• HTTP base endpoint https://api.xpressprotocol.com​

• WebSocket endpoint wss://sockets.xpressprotocol.com
