version: "1.0.1" name: rss-fetch description: RSS feed API for fetching news and articles. Use when user mentions "RSS", "feed", "RSS reader", "fetch feed", or asks to get news from RSS sources.

How to Use

1. Fetch Raw RSS Feed

bash

curl -s "https://hnrss.org/frontpage" | head -100

2. Parse RSS with xmllint

Extract titles from RSS feed:

bash

curl -s "https://hnrss.org/frontpage" | xmllint --xpath '//item/title/text()' - 2>/dev/null

Extract titles and links:

bash

curl -s "https://hnrss.org/frontpage" | xmllint --format - | grep -E '<title>|<link>' | head -20

3. Get Items with Details

bash

curl -s "https://hnrss.org/frontpage" | xmllint --xpath '//item' - 2>/dev/null | xmllint --format - | head -50

4. Parse Atom Feeds

Atom feeds use <entry> instead of <item>:

bash

curl -s "https://github.com/blog.atom" | xmllint --xpath '//entry/title/text()' - 2>/dev/null

RSS vs Atom Format

Element	RSS	Atom
Container	`<item>`	`<entry>`
Title	`<title>`	`<title>`

Guidelines

Check feed format: Use head first to see if it's RSS or Atom
Use xmllint: Best tool for XPath queries on XML
Handle errors: Some feeds may be slow or rate-limited
Respect robots.txt: Don't hammer feeds with requests
Cache results: Feeds don't update every second
