Error Handling

If the model doesn’t exist, you’ll receive a 404 error: 
{
  "error": {
    "message": "Model 'invalid-model' not found",
    "type": "invalid_request_error",
    "code": "model_not_found"
  }
}

​
Non-Chat Recommendation Metadata

For non-chat models, the detail route also returns lemondata.agent_preferences.<scene>. Use it to inspect:
  • preferred_rank
  • success_rate_24h
  • sample_count_24h
  • status
  • updated_at
The public response intentionally keeps basis.channel_id and basis.physical_model as null so agents can consume the recommendation signal without learning internal routing identifiers.
