## 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 x402-web-to-markdown-converter-9a5ad33f -d '<json body>'
```

Example prompt: Can you fetch the page at https://example.com/article and give me the full content as clean markdown so I can read it?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use web page to Markdown conversion without setting up your own scraping infrastructure. It's ideal for AI agents that need to ingest web content as clean text for summarization, indexing, or analysis, and where cost-per-call micropayment via x402 is acceptable. Prefer alternatives if you need bulk crawling, authenticated sessions, or JavaScript rendering.

## Known failure modes

- URL is unreachable or returns a non-200 status — likely returns ok: false with an error message
- Page is behind a login or CAPTCHA and cannot be fetched
- Payment via x402 fails or is rejected — request is not processed
- Malformed or missing URL input causes a 400-level error
- Page content is not parseable into meaningful Markdown (e.g. heavy JavaScript SPA with no static HTML)

## How this service works

Pay-per-request data tools for AI agents.

## Output

A JSON object with `ok: true` and a `data.markdown` field containing the fetched web page's content rendered as Markdown text.
