Request Generation Details API

The Request Generations Details API lets you retrieve detailed usage and performance metrics for a previously made generation request using its generation_id.

This is useful for auditing, debugging, or cost analysis — especially in BYOK and multi-team environments.

• Track cost per request

• Get the model and provider used for a generation

• See token usage

• Identify if a request used a BYOK (Bring Your Own Key)
