Overview

This API allows clients to interact with the CeFi trading platform for order management, market data retrieval, and account information.

Base URL

https://prod.truex.co/api/v1/

Authentication

Certain API requests must be authenticated using HMAC-SHA256 signature authentication.

API Versioning

The API uses date-based versioning via the X-Truex-Version header. To request a specific API version, include the header in your request:

X-Truex-Version: v2024_01_01

Supported Versions:

VersionStatusDescription
v2024_01_01Current (Default)Original API format - responses return raw data arrays/objects
v2026_01_23CurrentNew envelope format - responses wrapped in { "data": [...], "pagination": {...} }

If no version header is provided, the API defaults to v2024_01_01. Use the /api/v1/versions endpoint to discover supported versions programmatically.

Response Format by Version:

  • v2024_01_01: [{...}, {...}] (raw array) or {...} (raw object)
  • v2026_01_23: { "data": [...], "pagination": { "size": 10, "next_cursor": "..." } }

Error Response Format by Version:

  • v2024_01_01: RFC 7807 Problem Details format
  • v2026_01_23: { "error": { ...RFC 7807 Problem Details... } }

Deprecation Policy: When a version is deprecated, responses will include RFC 8594 headers:

  • Deprecation: Date when the version was deprecated
  • Sunset: Date when the version will be removed
