## 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-deployer-x402-deployer-workers-dev-fe2871d5 -d '<json body>'
```

Example prompt: Can you generate an RSS 2.0 feed from https://techcrunch.com/category/startups — use CSS selector '.post-block__title a' for article links if auto-detection doesn't work?

## When to prefer this

Use this endpoint when you need to create an RSS feed subscription from any arbitrary HTML webpage that does not natively provide one, especially when you want auto-detection of articles or need to specify custom CSS selectors for non-standard page layouts. Prefer this over generic scrapers when the output format must be a valid RSS 2.0 feed ready for feed readers or aggregators.

## Known failure modes

- Page URL unreachable or returns non-200 status — feed generation fails with error
- Auto-detection finds no article items and no CSS selectors provided — returns empty or minimal feed
- Invalid CSS selectors provided — selector-targeted extraction returns no items
- Page is JavaScript-rendered and server-side HTML lacks article content — incomplete feed
- Page blocks crawlers or returns CAPTCHA — cannot fetch HTML content

## How this service works

Generate a valid RSS 2.0 feed from any HTML page. Auto-detects article items, or accepts CSS selectors for tricky pages.

## Output

A valid RSS 2.0 XML feed containing detected or selector-targeted article items from the provided HTML page, including titles, links, and descriptions extracted from the page content.
