Docs

How to build on fstack demo: its HTTP API, and the files tools and language models read.

Reference

• API reference: every endpoint, who may call it, and what it returns.
• openapi.json: the same API as an OpenAPI 3.1 document, for client generators and API tools.
• llms.txt: an index of these docs and the help center for language models.

Guides

• Authentication: How a request proves who is signed in, and what the API answers when it can't.

Using the product rather than building on it? The help center has a how-to for every feature.
