data
array
Array of model objects.Each model contains:
  • id (string): Model identifier
  • object (string): model
  • created (integer): Creation timestamp
  • owned_by (string): Model provider
  • lemondata.category (string): Public model category
  • lemondata.pricing_unit (string or null): Public pricing unit when available
  • lemondata.capability_flags (object or null): Public capability summary
  • lemondata.supported_operations (array or null): Public non-chat operations for the model
  • lemondata.pricing_provenance (object or null): Public pricing source metadata
  • lemondata.public_contract_summary (object or null): Lightweight non-chat discovery summary with only public_operations and request_endpoint
  • lemondata.agent_preferences (object): Only returned when recommended_for is present
GET /v1/models is optimized for discovery. Detail-only metadata such as capability_flags, pricing_provenance, and the full public_contract live on GET /v1/models/{model}.
