FASHN API & SDKs

FASHN is an AI-first company specializing in human-centric generative image models tailored for fashion applications: virtual try-on, AI models, product photography, editing, and image-to-video. Everything runs through one prediction endpoint that takes a model_name plus an inputs object.

This skill helps you do two things:

1. Integrate FASHN into a project: write production code against the REST API, the TypeScript SDK (fashn on npm), or the Python SDK (fashn on PyPI).
2. Run a one-off generation inline: execute a single call and hand the result back to the user (see Inline quickstart).

When the user asks to add FASHN to their app / repo, integrate (write code into their project). When they ask to just do a try-on / generate an image now, run it inline.

Full per-endpoint parameter tables, the error catalog, webhooks, and credits live in reference.md. Load it when you need exact inputs for a given model_name.

Authentication

• Get an API key from the Developer API dashboard: https://app.fashn.ai/api
• All FASHN calls are server-side: never hard-code the key or expose it client-side.
• REST: send Authorization: Bearer $FASHN_API_KEY. Both SDKs read FASHN_API_KEY from the environment by default.
