How this service works
RSS / Atom feed discovery: finds feeds declared in a page's link tags, common feed paths (/feed, /rss, /atom.xml, /feed.xml) that respond, and feed URLs listed in robots.txt or sitemaps. Subscribe agents to any site's updates. $0.01 per site.
Output
A list of discovered feed URLs for the target site, categorized by discovery method (HTML link tags, common path probes like /feed /rss /atom.xml /feed.xml, robots.txt references, or sitemap entries), along with feed type (RSS or Atom) where detectable.
Example use cases
Blog reader feed aggregation
“Find all RSS and Atom feed URLs for arstechnica.com — I want to pull them into my feed reader so I get their latest articles automatically.”
Podcast feed discovery
“Can you locate the podcast RSS feed for npr.org? I need the feed URL to add it to my podcast app.”
Competitor monitoring setup
“Discover all feed URLs published by hubspot.com so I can monitor whenever they post new blog content or news.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/site/feedsWhen to prefer
Use this endpoint when you need to programmatically discover feed URLs for any website without already knowing the feed path. It combines multiple discovery strategies (HTML link tags, path probing, robots.txt, sitemaps) in a single $0.01 call, making it far more reliable than guessing common paths manually. Prefer this over the rss-to-json sibling endpoint when you don't yet have a feed URL and need to find one first.
Side effects
- Site has no discoverable feeds — returns empty list
- Target domain is unreachable or returns non-200 status
- Site blocks crawlers, returning 403 or CAPTCHA
- Malformed HTML prevents link-tag parsing
- robots.txt or sitemap is absent or unparseable
