Environments

Each exchange has its own hosts. The base URL is where your API requests and WebSocket connections go.

United States

Environment	Base URL	Status
Demo Shared demo environment. REST and WebSockets both live. No real money.	demo.stxapp.io	Available

Canada (Ontario)

Environment	Base URL	Status
Demo Shared demo environment for the Ontario exchange. No real money.	demo.stxapp.ca	Available
Production Live money. Create a separate API key at stxapp.ca: demo keys do not work in production.	api.on.stxapp.ca	Available

Which one should I use?

Pick the exchange you are integrating with. Accounts and keys do not carry across, so this decision comes before everything else. See United States and Canada if you are not sure which.

United States: use demo.stxapp.io, and register there for an account and key. Shared by every developer integrating with STX, so the order books carry real activity. No real money. US production is launching soon: start integrating on demo now.

Ontario: use demo.stxapp.ca, and register there for an account and key. When you are ready for production, register at stxapp.ca, create a new key there, and send your requests to api.on.stxapp.ca.

Caution

Production is live money. Point at it only once your integration is exercised end to end on demo.

A key belongs to one environment. Demo keys do not work in production: create a separate production key, or every request is rejected with a 401.
