## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vextorium-llms-txt-reader-9aec807a -d '<json body>'
```

Example prompt: Can you read the llms.txt for anthropic.com and give me the structured breakdown — title, summary, and all the sections with their links?

## When to prefer this

Use this endpoint when you need to programmatically read and parse a website's /llms.txt file into structured JSON rather than raw text. It is ideal when you want to understand what a site officially communicates to LLMs — its title, purpose summary, and navigational sections — without writing your own parser. Prefer it over raw HTTP fetching when you need clean structured output ready for downstream agent reasoning.

## Known failure modes

- Site does not have an /llms.txt file — returns null or empty fields
- URL is malformed or unreachable — request fails with error
- Site blocks automated fetches — may return empty or partial content
- llms.txt exists but is malformed — partial parsing with null fields

## How this service works

Read a website's /llms.txt (the standard that tells LLMs what a site is about) as structured data: title, summary, sections with links and descriptions, and whether llms-full.txt exists.

## Output

A JSON object containing the site URL, raw text of the llms.txt, parsed title, summary, an array of sections (each with a title and array of links with URL, link text, and description), total character count, total link count, and a boolean indicating whether llms-full.txt exists.
