Everything you can do on STX from code goes through these. Sign requests with your API key, call the REST endpoints for one-off reads and orders, and keep a WebSocket open for anything that changes while you watch it.
REST APIMarkets, orders, fills, positions, balances and history over HTTP, each endpoint with its parameters and a real response.
WebSocketsOrder books, trades and your own orders, fills, positions and balance, pushed as they change.
API keys and request signingCreate an Ed25519 key and sign every REST request and the WebSocket handshake with it.
CombosOne market across several legs, quoted by makers and accepted by the player over two WebSocket channels.
Prefer a library? The TypeScript, Python and C# SDKs sign for you and cover the same endpoints and channels.
