## How to use these docs as an AI agent

Every documentation page is available in three forms:

1. **HTML** at its public URL - e.g. `https://docs.zevpaycheckout.com/api/initialize-session`
2. **Raw markdown** at the same path with a `.md` suffix - e.g. `https://docs.zevpaycheckout.com/api/initialize-session.md`. Fetch this URL to get the unrendered source.
3. **Full corpus** - `/llms-full.txt` concatenates every page in this site into a single markdown file. Useful when you want the whole context in one request.

Every HTML page also includes:
- A `<link rel="alternate" type="text/markdown" href="...md">` tag pointing at the sidecar
- JSON-LD (`TechArticle`) describing the page
- A toolbar with "Copy markdown", "Open in ChatGPT", and "Open in Claude" buttons for human users who want to escalate the page into an AI assistant
