## 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 rss-and-atom-feed-reader-feed-info-a4deba2e
```

Example prompt: Can you pull up the feed metadata for https://feeds.npr.org/1001/rss.xml — I want to know the title, language, format, item count, and when it was last updated?

## When to prefer this

Use this endpoint when you need a quick metadata snapshot of a feed — title, language, format, item count, and date range — without retrieving individual items. Prefer this over item-fetching endpoints when you want to assess feed health, verify format compatibility, or display feed summary info to a user. It is the lightest-weight way to characterize a feed before committing to deeper processing.

## Known failure modes

- Invalid or non-feed URL returns an error verdict with reasons listed
- Feed URL requires authentication or returns 403/401 — access denied error
- Network timeout or unreachable host — null fields with error status
- Malformed XML that cannot be parsed — degraded flag set with reasons
- Feed URL redirects to a non-feed page — finalUrl differs, low item count or null fields

## How this service works

Fetch an RSS or Atom feed and return its title, site link, language, last update, item count, format and date range.

## Output

Returns a JSON object with feed title, site link, language, last updated timestamp, item count, feed format (RSS/Atom/RDF) and version, oldest and newest item dates, image URL, copyright, generator, TTL, content type, bytes read, whether it looks like a podcast, and whether results were truncated. Also includes verdict, degraded status, and redirect history.
