get_model_params — List every parameter a model accepts, with its type, allowed range or enum values, default, and any conditional rules governing when it applies.
list_models — List model ids in the modelparams.dev catalog, optionally filtered by provider or a substring.
list_provider_models — Everything one provider serves: its models, the wire id each one needs, their lifecycle status, and the parameter surfaces they expose — types, ranges, enum values, defaults, and conditional rules — in a single call.
