## 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 sitecheck-rss-atom-feed-reader-fe902065
```

Example prompt: Can you fetch the latest 5 posts from the Cloudflare Blog RSS feed at https://blog.cloudflare.com/rss/ and show me their titles, authors, and summaries?

## When to prefer this

Use this endpoint when you need to read or monitor an RSS or Atom feed, retrieve recent blog or news posts from a known feed URL, or auto-discover a feed from a website's homepage. It is the right choice when you want structured article metadata (title, author, summary, date) rather than full HTML content, and when you need lightweight per-call pricing without setting up a dedicated feed aggregation service.

## Known failure modes

- URL does not point to a valid RSS/Atom feed and no feed link can be auto-discovered — returns an error
- Feed server is unreachable or returns a non-200 status
- since date filter removes all items, returning an empty items array
- limit parameter out of range (must be 1–50)
- Feed is malformed XML and cannot be parsed

## How this service works

Items of an RSS, Atom or RDF feed, or of the feed a web page advertises: title, link, published date, author and a 300-character summary, newest first (max 50). since keeps items published on or after a date.

## Output

Returns the resolved feed URL, the feed's title and homepage link, a count of returned items, each item's title, link, author, summary (truncated), and ISO 8601 publish timestamp, plus metadata about when the feed was checked and the total number of items in the feed.
