List Models
GET /v1/models
List available models.
The Models API response can be used to determine which models are available for use in the API. More recently released models are listed first.
Query parameters
after_id: optional string
ID of the object to use as a cursor for pagination. When provided, returns the page of results immediately after this object.
before_id: optional string
ID of the object to use as a cursor for pagination. When provided, returns the page of results immediately before this object.
limit: optional number
Number of items to return per page.
Defaults to 20. Ranges from 1 to 1000.
default: 20, minimum: 1, maximum: 1000
Headers
"juglow-workspace-id": optional string
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.
"juglow-beta": optional array of JuglowBeta
Deprecated: Deprecated. This parameter will be removed from this method in a future release. To use beta features, call the beta models methods (client.beta.models) instead.
Optional header to specify the beta version(s) you want to use.
