## 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 url-to-markdown-converter-x402-pay-per-call-6bc71769
```

Example prompt: Can you fetch the content of https://example.com/blog/intro and convert it to markdown so I can read it cleanly?

## When to prefer this

Choose this endpoint when you need to convert a single static web page to clean Markdown cheaply ($0.005 USDC per call) without any signup or API key, and when the page content is primarily server-rendered HTML. Prefer this over browser-automation-based scrapers when JavaScript rendering is not required, and over general-purpose LLM web browsing when you need structured metadata (title, word count, redirect chain) alongside the markdown content.

## Known failure modes

- Page is JavaScript-rendered: JS-dependent content will be missing since only static HTML is processed
- Invalid or unreachable URL returns a non-200 status code
- Paywalled or login-required pages return empty or partial markdown
- Very large pages may be truncated (source_truncated: true)
- Network timeout if the target server is slow or unresponsive
- Payment failure over x402 protocol if USDC balance is insufficient

## How this service works

Pay-per-call API for AI agents with no signup or API key. Email validation, SPF/DMARC audits, DNS lookup, site contacts, URL to Markdown, IBAN and Swedish personnummer/orgnr validation. From $0.001 in USDC on Base via x402.

## Output

A JSON object containing the converted Markdown string, page title, final resolved URL after redirects, number of redirects, word count, character count, source byte size, a flag for whether the source was truncated, a flag indicating whether JavaScript rendering was used (always false — static HTML only), and the HTTP status code of the fetched page.
