Models API Standard

Our Models API makes the most important information about all LLMs freely available as soon as we confirm it.

​
API Response Schema

The Models API returns a standardized JSON response format that provides comprehensive metadata for each available model. This schema is cached at the edge and designed for reliable integration for production applications.

​
