## 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 agentshelf-rss-atom-feed-parser-8b86e075 -d '<json body>'
```

Example prompt: Can you fetch and parse the RSS feed at https://feeds.arstechnica.com/arstechnica/index and give me the titles, links, and summaries of the latest articles?

## When to prefer this

Choose this endpoint when you need to ingest a known RSS or Atom feed URL and get structured item data (title, link, date, summary) quickly and cheaply at $0.004 per call. It is SSRF-safe, making it suitable for agent pipelines that accept user-supplied URLs. Prefer the free sandbox endpoint POST /v1/sandbox/feed-parse for testing before incurring costs.

## Known failure modes

- Invalid or non-feed URL returns a parsing error
- Private/internal IP addresses are rejected (SSRF protection)
- Feeds with more than 50 items are truncated to 50
- Malformed XML in the feed may cause a parse failure
- Unreachable URLs time out
- Non-RSS/Atom content at the URL returns a format error

## How this service works

Call when an agent needs an RSS/Atom feed parsed into title plus up to 50 items (link, published, summary). SSRF-safe. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/feed-parse first.

## Output

Returns the feed's title and up to 50 items, each containing the item's link URL, published timestamp, and a plain-text summary/description. The response is structured as JSON for easy agent consumption.
