API Reference: Agent and Single-Task Endpoints

Welcome to the FASHN API Reference. Start with the FASHN Agent API, which plans and runs the steps a request needs, or call a single-task endpoint directly.

Agent Images

Describe the images you need in plain language and attach up to six references, and the FASHN Agent plans and runs the generations: on-model photos, packshots, catalog images, and lookbooks
