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:

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": { "limit": 10, "next_cursor": "..." } }
