## 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 codepulse-api-rss-feed-parser-4e0c96e4 -d '<json body>'
```

Example prompt: Can you fetch and parse the RSS feed at https://news.ycombinator.com/rss and give me the latest article titles and links?

## When to prefer this

Use this endpoint when you need to parse a known RSS or Atom feed URL into structured data with minimal setup and no API key required. Ideal for AI agents that need to monitor or extract content from blogs, news sites, or podcasts via their RSS feeds. Best when pay-per-call pricing ($0.001 USDC via x402 on Base) is preferred over a subscription.

## Known failure modes

- Invalid or unreachable RSS feed URL returns an error or low confidence result
- Non-RSS URL (e.g. plain HTML page) may return supported:false with empty items
- Malformed XML in the feed may produce warnings or partial results
- Rate limiting or network timeouts on the target server may cause failures
- Feed with no items returns an empty items array

## How this service works

Parses any public RSS or Atom XML feed URL into structured JSON.

## Output

Returns a structured JSON object with feed metadata (title, link) and an array of items each containing title, link, and pubDate. Also includes a confidence rating (e.g. 'high'), a data_as_of timestamp, any warnings encountered during parsing, a supported flag, and a disclaimer note.
