## 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 sitesignal-rss-atom-feed-snapshot-c86fb138
```

Example prompt: Can you fetch the latest 10 entries from the Hacker News RSS feed at https://news.ycombinator.com/rss and give me each item's title, link, and a short summary?

## When to prefer this

Use this endpoint when you need to quickly parse a public RSS or Atom feed URL into structured, deduplicated entries without standing up your own feed parser. It is ideal for content aggregation, change monitoring, and podcast or blog tracking where stable fingerprints are needed to avoid reprocessing seen items. Prefer it over generic scraping endpoints when the source already exposes a standard syndication feed.

## Known failure modes

- Non-RSS/Atom URL returns a parsing error
- Private or paywalled feed returns access denied
- Malformed XML causes a parse failure
- Feed with zero entries returns an empty list
- Network timeout if the feed host is slow or unreachable
- Exceeding the limit parameter maximum (20) returns a validation error

## How this service works

Parse a public RSS or Atom feed into recent source-linked entries with stable fingerprints and bounded summaries.

## Output

Returns a structured list of recent feed entries, each containing the title, source link, publication timestamp, bounded text summary, and a stable fingerprint for deduplication — all derived directly from the parsed RSS or Atom XML.
