Provider x Model Supported Parameters

List Provider-Model Pairs

get

Returns a flat array of every (provider, model) pair available on FastRouter. Each entry shows how a given provider exposes a model: the provider's provider_model_id, its own pricing, the parameters it accepts (with detailed input formats in supported_parameters_v2), and provider-specific capability flags in extra_params.

This is the most granular view — use it to filter by provider or to discover all the provider variants of a model. For a single model's full provider breakdown, use GET /api/v1/modelProviderData?id={modelId}.

Tip: Inspect supported_parameters_v2 on each entry to see exactly which parameters a provider accepts (with their data types, enums, and min/max ranges).
