## 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-feed-to-json-converter-e0bc3474 -d '<json body>'
```

Example prompt: Can you fetch the RSS feed at https://feeds.arstechnica.com/arstechnica/index and convert it to JSON, returning up to 20 items?

## When to prefer this

Use this endpoint when you need to programmatically consume an RSS or Atom feed as structured JSON rather than raw XML, especially in agent pipelines that need to iterate over feed items. It is ideal when you have a known feed URL and want a clean, paginated JSON representation without writing your own XML parser. Prefer this over generic web scrapers when the source publishes a proper RSS feed.

## Known failure modes

- Invalid or malformed RSS feed URL returns an error
- Non-RSS URL (e.g. a plain HTML page) may fail to parse
- Feed URL is unreachable or returns a non-200 HTTP status
- Limit parameter outside 1–100 range is rejected
- Malformed XML in the RSS feed causes a parse failure

## How this service works

Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.

## Output

A JSON object containing the parsed RSS feed data, including feed-level metadata (title, description, link) and an array of feed items (entries/articles) each with fields such as title, link, publication date, description, and author, up to the specified item limit.
