## 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-webpage-to-markdown-api-f4457517 -d '<json body>'
```

Example prompt: Can you fetch the webpage at https://www.paulgraham.com/avg.html and convert it to clean markdown so I can feed it into my language model?

## When to prefer this

Use this endpoint when you need to convert a live webpage into clean, structured Markdown for ingestion by an LLM or AI agent, especially in no-signup, no-API-key contexts where micropayment via x402/USDC on Base is acceptable. Prefer this over general-purpose scraping APIs when LLM-readability of the output is the primary concern and you want a simple pay-per-call model.

## Known failure modes

- Invalid or unreachable URL returns success:false with an error message
- Non-HTTP/HTTPS URLs may be rejected
- Pages behind authentication or paywalls may return incomplete or empty markdown
- Payment failure via x402 protocol results in 402 Payment Required response
- Timeout on slow-loading pages may result in partial or empty content
- Very large pages may produce truncated markdown output
