Get a model · Fusara API

Overview

Browse published models without authentication. A valid API key adds checkpoint choices accessible to that account. Invalid supplied credentials are rejected. include=presentation returns the same profile schema, defaults, labels, controls and capability rules used by Workspace; execution and provider configuration are never exposed. Responses must not be stored by shared caches.

Available without an API key. Account-specific inputs may require authentication. Authentication →
