## 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 longwatch-rss-atom-feed-reader-f1a55f5d -d '<json body>'
```

Example prompt: Can you grab the latest articles from the RSS feed at https://feeds.arstechnica.com/arstechnica/index and show me what's been published recently?

## When to prefer this

Use this endpoint when you need a single, immediate lookup of an RSS or Atom feed's latest items and do not need to track changes over time or resume from a prior position. Prefer this over longwatch's persistent watch endpoints when stateless, one-shot retrieval is sufficient and you don't want to manage a watch_id or cursor across sessions.

## Known failure modes

- Invalid or malformed URL returns an error
- Private or paywalled feed returns access denied or empty response
- Non-RSS/Atom URL returns parse error
- Feed server is unreachable or times out
- Malformed XML in feed causes parse failure
- Rate limits on the feed host may cause failures
