## 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 sift-web-tools-feed-discovery-v1-feeds-46fe9a39
```

Example prompt: Can you find and list the latest 5 feed items from the RSS feeds available on python.org?

## When to prefer this

Use this endpoint when you need to discover and read syndicated content (RSS/Atom) from any website without maintaining a feed reader. Prefer it over generic page-fetch endpoints when you specifically want structured feed entries and item titles rather than raw HTML. Ideal for content monitoring, news aggregation, and podcast discovery workflows where you need regularly-updated item lists. Pay only on success ($0.002 USDC per successful call).

## Known failure modes

- URL has no discoverable RSS or Atom feeds — returns empty feeds array
- Target site is unreachable or returns non-200 — call is not charged
- Invalid or malformed URL parameter — returns error
- Feed content is behind authentication — cannot be parsed
- items parameter out of expected range — may be clamped or return default 10

## How this service works

Find a site's RSS/Atom feeds and return the latest items. Discovers RSS or Atom feeds for a site or page and returns the latest items with title, link, date and summary.

## Output

A JSON object containing a list of discovered feeds, each with a feed title and an array of item objects (including item titles). Also includes a total feed_count indicating how many feeds were found on the given URL.
