search_modelsAnswer

Search the LLM parameter catalog. Filter by free-text query, provider slug, required parameter path(s), API surface, and auth type (api_key | subscription | all). Also mirrors the query onto the page's visible filters. Returns matching model ids.

get_model_parametersAnswer

Fetch the full parameter set for one model by id (e.g. anthropic/claude-opus-4-7, or append -subscription for the subscription variant). Returns every parameter with type, default, range, allowed values, applicability conditions, and deprecation status.
