How this service works
RSS/Atom feed validator: fetches the feed, detects the format and version (RSS 2.0, Atom 1.0, RSS 1.0/RDF), checks well-formedness and required elements (title, link, id/guid, dates), counts items, flags missing/invalid dates, duplicate guids, relative links, missing descriptions, and the content type served. Returns valid true/false with errors and warnings. $0.01 per feed.
Output
Returns a JSON object with a boolean 'valid' field, a detected feed format and version (e.g. RSS 2.0, Atom 1.0, RSS 1.0/RDF), item count, and arrays of errors and warnings covering issues such as missing required elements (title, link, id/guid, dates), duplicate GUIDs, relative links, missing descriptions, and the HTTP content type served.
Example use cases
Pre-publish blog feed audit
“Before I launch my new blog, can you validate the RSS feed at https://newblog.example.com/rss and tell me if there are any errors, missing required fields, or warnings I should fix?”
Podcast feed compliance check
“Check my podcast's Atom feed at https://mypodcast.com/feed/atom.xml — I need to know if it's valid, whether all episodes have proper dates and IDs, and if there are any duplicate GUIDs.”
Third-party feed health monitoring
“I'm consuming a third-party news feed at https://newssite.com/rss.xml in my app — can you validate it and flag any issues like relative links, missing descriptions, or wrong content types that might cause problems?”

Endpoint
GEThttps://intel.rallylive.ca/dev/feed-validateWhen to prefer
Use this endpoint when you need a quick, automated, per-feed validation check covering format detection, required element presence, GUID uniqueness, date validity, and content-type correctness — especially before publishing a feed, integrating a third-party feed, or monitoring feed health. It is purpose-built for RSS/Atom syndication feeds and covers common aggregator-compatibility issues in a single call at low cost ($0.01 per call).
Side effects
- Feed URL is unreachable or returns non-200 HTTP status
- URL does not point to an RSS/Atom feed (e.g. returns HTML)
- Feed is so malformed it cannot be parsed at all
- Network timeout fetching the feed
- Private or authentication-gated feed URL returns 401/403
