## 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 saylor-agent-tools-rss-atom-json-feed-discovery-b8bc82b2
```

Example prompt: Can you find all the RSS, Atom, or JSON feeds available on nytimes.com so I can subscribe to their latest articles?

## When to prefer this

Use this endpoint when you need to programmatically discover syndication feeds (RSS, Atom, JSON Feed) for any public webpage or domain, particularly when building feed aggregators, content monitoring pipelines, or helping users subscribe to sites. Prefer this over manual scraping when you want a structured, agent-ready response that normalizes canonical and final URLs alongside feed metadata.

## Known failure modes

- URL is not publicly accessible or returns non-200 status — found: false with empty feeds array
- Page has no discoverable feeds — found: false
- Invalid or malformed URL input — request error
- Timeout fetching the remote page
- URL parameter missing — 400-level error

## How this service works

RSS, Atom and JSON feed discovery for any web page

## Output

Returns a JSON object indicating whether feeds were found (boolean), an array of discovered feed objects with their URLs and types, the canonical URL of the page queried, and the final resolved URL after any redirects, plus the source from which feeds were discovered.
