## 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 bot-bazaar-llms-txt-linter-2a593b0b
```

Example prompt: Can you lint my llms.txt document structure — the title is 'My Agent API' — and tell me if the H1 title, blockquote summary, H2 sections, and context window budget all pass?

## When to prefer this

Use this endpoint when you need to validate an llms.txt agent documentation file against the specification — particularly checking H1 titles, blockquote summaries, H2 section structure, and context window budgets. Ideal for CI/CD pipelines, pre-publish checks, or debugging why an agent documentation file is failing discovery.

## Known failure modes

- Missing required title query parameter returns validation error
- Malformed or missing input object returns schema error
- H1 title not found yields lint failure with specific error
- Context window budget exceeded triggers budget warning
- Network timeout on the fly.dev host
- Payment required (HTTP 402) if USDC payment not provided

## How this service works

Lint an /llms.txt agent documentation structure (H1 title, blockquote summary, H2 sections, context window budget).

## Output

Returns lint results identifying structural issues in the llms.txt file, including whether the H1 title is present and correctly formatted, whether a blockquote summary exists, whether H2 sections are properly structured, and whether the document fits within context window budget constraints.
