## 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-tools-rss-atom-rdf-feed-parser-1dc71c02
```

Example prompt: Can you fetch the Cloudflare blog RSS feed at https://blog.cloudflare.com/rss/ and give me the latest 10 articles — titles, links, and summaries?

## When to prefer this

Choose this endpoint when you need to ingest structured article or podcast data from a known RSS/Atom/RDF feed URL, or when you only have a blog or website URL and need the agent to auto-discover and read its feed. It is ideal for content aggregation, newsletter curation, monitoring blog output, and building reading lists. Prefer it over a general web-scraping endpoint when the target site publishes a machine-readable feed, as it gives cleaner, structured data with dates and authors.

## Known failure modes

- URL is not a valid feed and no linked feed is discoverable — returns an error
- Feed URL is unreachable or returns a non-200 status
- Feed XML is malformed and cannot be parsed
- limit parameter out of range (must be 1–100)
- URL is not an https URL — rejected by schema
- Feed requires authentication and is not publicly accessible

## How this service works

The items of an RSS, Atom or RDF feed as JSON (title, link, id, published date, author, plain-text summary). Given a web page instead of a feed, it finds the feed the page links to.

## Output

A JSON object containing the feed's title, detected format (rss, atom, or rdf), total number of items returned, and an array of items each with a link, title, plain-text summary, published date, optional author, and optional ID.
