Technical details
Endpoint
GEThttps://api.x402node.dev/feed/discoverWhen to prefer
Use this endpoint when you need to programmatically discover the syndication feed URLs for any website without knowing them in advance. Ideal for agents building feed readers, podcast indexers, or content aggregators that need to subscribe to sites dynamically. Prefer this over manual feed guessing or scraping when you want structured, typed feed metadata from a single API call.

- Target URL has no link rel=alternate tags — returns empty array
- Target URL is unreachable or returns non-200 — likely returns error or empty result
- Malformed URL input — may return validation error
- Site uses JavaScript-rendered feeds not present in raw HTML — feeds not detected
- Payment not received or insufficient — 402 Payment Required
