The AI Gateway exposes endpoints that are fully compatible with the OpenAI API, letting you use every model available in the AI Gateway without changing your application logic. Keep the existing OpenAI client, point it to the Orq.ai proxy baseURL, and continue as usual.
For the OpenAI API specification, see the API Reference
Drop-in Integration (No Code Changes)
  1. Keep your existing OpenAI SDK or HTTP integration.
  2. Set the base URL to https://api.orq.ai/v3/router
  3. Use the Orq.ai API Key in the Authorization header.
  4. Call the same endpoints and payloads already used with OpenAI.

​
Base URL

OpenAI-compatible endpoint: 
https://api.orq.ai/v3/router
All routes below are relative to this base URL and mirror OpenAI’s request/response formats.

​
Authentication

Authenticate with the Orq.ai API key via the Authorization: Bearer $ORQ_API_KEY header.
To learn more about Orq API Key, see API Key.
Minimum headers:
  • Authorization: Bearer $ORQ_API_KEY
  • Content-Type: application/json

Error Handling & Compatibility Notes

  • HTTP status codes and error structures follow OpenAI’s conventions.
  • Streaming, function/tool calls, and multimodal inputs (images/files) are supported on /chat/completions.
  • The AI Gateway is versioned under /v3/router. Ensure clients target this path.
