GET
List model endpoint capabilities
Call this endpoint before sending a request to confirm that a model, provider, endpoint and parameter combination is available. For openai/gpt-6-astra:
Each entry in endpoints is one provider route for one endpoint: To compare models first, use List models; to see every endpoint the API exposes, use List endpoints.

Include planned and inactive routes

The default availability=active only returns publicly routable rows. Use availability=all to inspect coming-soon and inactive routes:
Only route production traffic to a row whose routable is true and status is active.

Filter routes

These filters accept repeated parameters or a comma-separated list: provider, provider_status, provider_routing_status, model_routing_status, capability_status, provider_availability_status, provider_availability_reason, status, and supported_parameters (alias params). List models describes their values. This returns OpenAI routes that support reasoning_effort:
