How this service works
The rel="canonical" links of a page: every matching <link>/<a> with href, resolved to absolute URLs, with a count. Duplicate-content and canonicalisation checks. $0.01 per page.
Output
Returns every <link rel="canonical"> and <a rel="canonical"> element found on the fetched page, with each href resolved to its absolute URL and a total count of matching elements. Useful for confirming correct canonical setup or identifying duplicate/conflicting canonical declarations.
Example use cases
SEO canonical tag audit
“Pull all the rel="canonical" links from https://shop.example.com/product/blue-widget and tell me what URLs they resolve to — I'm trying to find out if this product page is pointing to the right canonical.”
Duplicate content check before launch
“Before we go live, can you check https://staging.mysite.com/landing-page for any canonical link tags and count how many there are? I want to make sure we're not accidentally signalling a different canonical URL.”
Crawl quality verification for SEO tool
“I'm auditing https://news.example.com/article/12345 — fetch it and list every rel canonical href you find, resolved to absolute URLs, so I can confirm there's no conflicting canonicalisation.”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/link-rel/canonical?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to extract and validate rel="canonical" link elements from a page for SEO auditing, duplicate-content checks, or canonicalisation verification. It is purpose-built for canonical link extraction rather than generic HTML scraping, and resolves all hrefs to absolute URLs automatically. Prefer it over full-page scrapers when only canonical metadata is needed at low cost ($0.01/call).
Side effects
- Page URL is unreachable or returns a non-200 status — extraction fails with no results
- Page has no canonical tags — returns an empty list with count 0
- Relative URLs that cannot be resolved due to missing base URL context — may return partially resolved results
- Rate limiting or payment failure via x402 — call is rejected before fetching
- Malformed HTML prevents proper link element parsing — may return incomplete results
