All API errors return a JSON body with a detail field:

{ "detail": "Error description" }

HTTP Status	Meaning	Common Causes
`400`	Bad Request	Invalid input, missing required fields
`401`	Unauthorized	Missing or invalid authentication token
`403`	Forbidden	Insufficient permissions
`404`	Not Found	Resource doesn't exist
`409`	Conflict	Duplicate name
`413`	Payload Too Large	File exceeds `BIGRAG_MAX_UPLOAD_SIZE_MB`
`500`	Internal Server Error	Server-side error

Every HTTP response includes an X-Request-ID header. Send your own value to correlate client logs with API logs, or let bigRAG generate one.
