llms.txt

Serve llms.txt content through your existing docs API — no extra route files needed. Just enable it in your config.

What is llms.txt?

llms.txt is a standard for making website content accessible to LLMs. It's served via query params on your existing /api/docs endpoint:

• /api/docs?format=llms — A concise markdown listing of all pages with titles, URLs, and descriptions
• /api/docs?format=llms-full — The full stripped content of every page, ready for LLM consumption

Quick Start

llmsTxt: {
  enabled: true,
  baseUrl: "https://docs.example.com",
}

That's it. The existing API handler serves the content automatically — no extra route files needed.

Configuration Reference

All options go inside the llmsTxt object in docs.config.ts:

export default defineDocs({
  llmsTxt: {
    // ... options
  },
});

llmsTxt.enabled

Enable or disable llms.txt generation.

llmsTxt.baseUrl

Base URL prepended to all page links in the generated files.

llmsTxt: {
  enabled: true,
  baseUrl: "https://docs.example.com",
}

llmsTxt.siteTitle

Title shown at the top of the generated files. Falls back to nav.title if not set.

llmsTxt.siteDescription

Description shown below the title.

How It Works

No extra route files are needed. The existing API handler (/api/docs on Next.js, or your framework's equivalent) serves the llms.txt content when you pass the format query parameter:

• GET /api/docs?format=llms — concise page listing
• GET /api/docs?format=llms-full — full page content

This works identically across Next.js, SvelteKit, Astro, and Nuxt — just enable llmsTxt in your config and the existing createDocsAPI() / createDocsServer() handler takes care of the rest.
