What it asks for
- Endpoint — for example, POST /v1/users
- Base URL / version — for example, https://api.example.com (version 2026-03-10)
- What it does — for example, Creates a new user account and returns the user object
- Parameters (one per line) — for example, email (string, required)
name (string, optional)
role (enum: admin|member)
- Response shape — for example, { "id": "usr_123", "email": "...", "created_at": "..." }

- Auth
What you get
A finished api documentation you can edit, export or carry straight into another surface — a document to refine, a PDF to send, a deck to present. It stays in your library, so you can come back and change it.
Or just ask
You do not have to fill the form at all. Describe what you need in chat and Xenition fills it in from what you said, then asks only about the gaps.
