API Docs Generator

Paste an OpenAPI 3.0 spec and generate the same self-contained HTML reference docs the product ships — sidebar navigation, live search, parameter tables, and request/response examples derived from your schemas.

Docs Generator

Edit the bundled OpenAPI spec (or paste your own), pick an accent, and the generator renders the single-file HTML docs page — exactly what src/main.py --spec openapi.json --output docs.html produces.
