Models x Provider Breakdown

Get Model with Provider Breakdown

get

Returns the same model object as GET /api/v1/models for a single model plus a provider_data array showing every provider that serves this model, with each provider's own provider_model_id, pricing, supported parameters (and their per-provider schemas via supported_parameters_v2), and provider-specific capabilities.

Use this to figure out:

• which providers serve a given model,

• how a provider exposes the model (its provider_model_id, pricing, what parameters it accepts).

Query parameters

The model ID in provider/model format.

Example: bytedance/seedream-4.5

Bad Request - The request is malformed. This could be due to missing parameters, invalid formats, or routing errors.

Note: the 400 body shape is not uniform. Validation errors return the structured object below, but routing/model errors may instead return a plain string: { "error": "<message>" }. A few endpoints (e.g. some file operations) may return a plain-text body rather than JSON.
