## 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-agent-tools-web-page-to-markdown-converter-b37509cb
```

Example prompt: Can you fetch the content of https://en.wikipedia.org/wiki/Artificial_intelligence and give it to me as markdown so I can read through it?

## When to prefer this

Choose this endpoint when an agent needs to read and process the textual content of a specific public web page without managing API keys or accounts. It is ideal for LLM pipelines that need clean markdown input from arbitrary URLs, paid frictionlessly per-call via USDC on Base or Solana using the x402 protocol. Prefer this over headless browser tools when lightweight markdown extraction suffices and over full-site crawlers when only a single page is needed.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns error or empty content
- URL points to a non-HTML resource (PDF, image, binary) — markdown may be empty or malformed
- Page uses heavy JavaScript rendering — content may be incomplete if JS is not executed
- Invalid or malformed URL provided — schema validation error on required 'url' query param
- Payment failure via x402 protocol — 402 response returned before content is fetched

## How this service works

Pay-per-call tools for AI agents. USDC on Base or Solana via x402 v2; no keys, no accounts.

## Output

A JSON object containing the original URL, the page title, the full page content rendered as Markdown, and a word count integer. The markdown strips HTML boilerplate and navigation, leaving readable prose and structure.
