How this service works
The rel="pingback" links of a page: every matching <link>/<a> with href, resolved to absolute URLs, with a count. Link-relationship discovery. $0.01 per page.
Output
Returns a list of resolved absolute URLs found in <link> or <a> elements with rel='pingback' on the target page, along with a count of how many such links were discovered.
Example use cases
Discover WordPress pingback endpoint
“Check https://myblog.wordpress.com and tell me what pingback URL it advertises in its link tags — I need the absolute URL.”
Audit site for pingback support
“Scan https://techcrunch.com and let me know if it has any rel=pingback links and how many you find.”
Map pingback targets for link monitoring
“Pull all the pingback link-relations from https://arstechnica.com so I can see which endpoints they're pointing to.”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/link-rel/pingback?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to discover rel='pingback' link relationships on a page — particularly useful for auditing WordPress or other CMS sites that advertise pingback endpoints, or when building tools that need to map out which pingback servers a site uses. Prefer this over a generic HTML scraper when you want pingback links specifically enumerated and resolved without writing your own parsing logic.
Side effects
- Page is unreachable or returns a non-200 status, resulting in an empty or error response
- Target page has no rel=pingback links, returning a count of zero and an empty list
- Relative URLs that cannot be resolved due to a missing or ambiguous base URL
- Rate limiting or blocking by the target site preventing page fetch
- Malformed HTML on the target page causing link extraction to miss some elements
