API Reference

The Kaizen REST API provides endpoints for managing tasks, feedback, prompts, optimization jobs, traces, and API keys.

Base URL


http://localhost:8000/api/v1

All endpoints (except /health) require an X-API-Key header:


curl -H "X-API-Key: your-api-key" http://localhost:8000/api/v1/tasks

The API uses RFC 7807 problem details for error responses:


{
  "type": "https://kaizen.dev/errors/not-found",
  "title": "Not Found",
  "status": 404,
  "detail": "Task with ID 'abc' not found"
}
