How this service works
Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.
Output
A JSON object containing the queried URL, the count of discovered feeds, and an array of feed objects each with an href (feed URL) and type (e.g. application/rss+xml or application/atom+xml).
Example use cases
Blog subscription setup
“Find all the RSS feeds on https://theverge.com so I can add them to my feed reader.”
Podcast feed discovery
“What's the RSS feed URL for https://changelog.com/podcast? I want to subscribe in my podcast app.”
News aggregator setup
“Check if https://techcrunch.com has any RSS or Atom feeds available and give me the links.”
Technical details
Endpoint
GEThttps://volkov.evgeny.m2.fvds.ru/pay/feeds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to auto-discover syndication feed URLs (RSS/Atom) for any given webpage without manually parsing HTML. Prefer this over manual scraping when you need a lightweight, pay-per-call solution that handles feed link extraction for you, especially in agent workflows that aggregate multiple news or content sources dynamically.
Side effects
- URL not found or unreachable — returns empty feeds array or error
- No feeds present on the page — returns count: 0 with empty feeds array
- Invalid or malformed URL input — request may fail or return error
- Payment of 0.002 USDC on Base not fulfilled — HTTP 402 returned before feed data
