Welcome to the ZetariumDex API reference — HMAC-signed REST and public WebSocket access to the perpetual futures exchange.
The web UI flow is not documented here. Users register and create API keys through the web interface; clients then use those keys to call HMAC-signed REST endpoints and consume the public WebSocket stream.
