Every API, one clean contract.

Fetch ONE feed URL (RSS 2.0/0.9x, RSS 1.0/RDF, Atom, JSON-Feed 1.1 — auto-detected) and normalise it into one clean JSON schema. Broken XML, HTML entities, encoding mess and truncated feeds are repaired automatically (recovery step reported in meta).

  "limit": 10
}

Find the feeds of ANY website: parses <link rel=alternate> tags + visible anchor hints, then probes common feed paths at BOTH the host root (/feed, /rss.xml, /atom.xml, /index.xml, …) AND under the given path (e.g. /r/programming/.rss). Every candidate is fetched and VERIFIED as a real parseable feed before being returned — so it works even on sites that don't declare a feed link-tag.

}

Merge up to 10 feeds into ONE de-duplicated, date-sorted stream. Duplicates are detected on a canonical link key (tracking params stripped) falling back to guid/title. Each item carries its source_feed.

{
  "urls": [
    "https://feeds.bbci.co.uk/news/world/rss.xml",
    "https://feeds.bbci.co.uk/news/technology/rss.xml"
  ],
  "limit": 20
}

Keyword-filter feed items (like RSSHub filter / Feedly search, but no account). Searches title/summary/author/categories (and content_html when include_content=true); multi-word queries match any or all terms; exclude= drops unwanted items.

{
  "url": "https://feeds.bbci.co.uk/news/world/rss.xml",
  "query": "a e i o u",
  "match": "any"
}

Fetch up to 20 feeds in ONE call (concurrent, fault-isolated): each feed returns independently with its own ok/error — one dead feed never fails the batch.

    "https://feeds.bbci.co.uk/news/world/rss.xml",
