karbonhq/karbon-api-reference — reverse-engineered prompt

Build me a simple public documentation site for the Karbon API v3. I want developers to be able to open one clean web page, browse the API from an OpenAPI 3.1 JSON file, search endpoints, expand request and response details, and understand how to authenticate.

Please include a separate developer guide page that explains the practical stuff in plain language, like authentication, pagination, filtering, and common usage patterns. Also add easy links to the API reference, the raw OpenAPI spec, and the guide.

Keep it as a static site that can be hosted on GitHub Pages with no backend. Make it feel polished but lightweight, with a favicon, simple branding, and readable layout. The spec should live as KarbonAPI.json and the guide as KARBON_API.md so they’re easy to update later. If you need current OpenAPI docs or static API explorer docs, look them up online.
