string workspaceID

Optional header to select the Workspace for this request. The value is a Workspace ID (for example, wrkspc_011CZkZaBF1tNoB5wlCeusgy).

Only needed for credentials that can act on more than one Workspace. A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace.

Returns
class BetaModelInfo { Type = "model"; ID; AllowedFallbackModels; /* 5 more */ }
JsonElement Type = "model"

Object type.

For Models, this is always "model".

required string ID

Unique model identifier.

required IReadOnlyList<string>? AllowedFallbackModels

Model IDs this model accepts as fallbacks[i].model on the Messages API. An empty list means the fallbacks parameter is not supported for this model as primary.
