Overview

OpenAPI specs and WebSocket reference. Use the section that matches your access:

• Public API — Public API docs (REST & WebSockets, no auth)
• Trader API — Trader API docs (Trader API credentials)
• Partner API — Partner API docs (Partner API credentials)

Contents

• OpenAPI specs — Public, Partner, and Trader documents; which base URL and credentials each spec uses
• WebSockets — where real-time data lives (Public WebSocket vs Trader streaming vs Partner FIX)
• Rate limits and best practices — gateway limits, 429 backoff, Public / Trader / Partner REST
• API versioning — how we version APIs and what we guarantee within a version
• Pagination — pagination varies by API (low-latency trading vs Partner/REST); see the spec for each endpoint
• HTTP status codes — 400, 401, 403, 429, 5xx and how we use them
