  summary: Authenticated Responses inference plus public catalog and route-status metadata.
  description: 'This description covers Infer''s public paid-beta integration surface: the authenticated Responses endpoint and model list, plus the unauthenticated catalog and status resources. Public registration creates a workspace; the account email must be verified, the live wallet must be funded, and a scoped live API key must be created before paid live inference. Route availability is dynamic, so read the public status resource before sending traffic. Strict supplier-evidence readiness is a separate standard, and Infer does not attest an upstream provider identity.'

      summary: Create a Responses-style inference request
      description: Authenticates an Infer API key, validates a canonical model selector and routing policy, reserves the request's spend ceiling, and returns a charge record reference after completion. Exact model-family selection does not cross into another model family. Verified, funded public paid-beta workspaces can send live requests while the selected service is operational. Route eligibility still depends on the current environment, capabilities, privacy policy, region, health, authorization, and capacity; read /api/public/status immediately before use. A response model name or charge record does not attest upstream provider identity or satisfy Infer's separate strict supplier-evidence standard.
