Endpoints

Endpoints

Platform-funded routing only. Caller BYOK credentials and OIDC-based upstream authentication are intentionally excluded; authenticate with a MiniRouter bearer key.
Paths
/v1/chat/completions/v1/messages/v1/responses
Structured output

Not enforced; a requested format is dropped and the answer is plain text. How it works
