How this service works
Extract the page's canonical and alternates as markdown: fetches the URL, pulls every canonical and alternates element and returns them as a Markdown list, with a count. Structured, one-element-type extraction for agents and pipelines; no browser needed. $0.01 per page.
Output
A Markdown-formatted list of all canonical and alternate link elements found on the fetched page, along with a count of how many elements were extracted. Each item in the list represents one canonical or alternate link element discovered in the page's HTML head.
Example use cases
SEO canonical tag audit
“Pull the canonical and alternate link elements from https://www.myshop.com/products/blue-sneakers and give me a Markdown list so I can check if the canonical is set correctly.”
Multilingual hreflang discovery
“Fetch https://globalsite.com/en/about and extract all the alternate hreflang links — I want to see which languages and regions the page targets, formatted as a Markdown list.”
Content pipeline metadata extraction
“For each article URL I give you, starting with https://news.example.com/article/12345, extract the canonical and alternate elements and return them as Markdown so I can feed the results into my content deduplication pipeline.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/page/canonical-and-alternates/markdown?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a clean, structured Markdown list of only canonical and alternate link elements from a page — ideal for SEO audits, hreflang discovery, and content deduplication pipelines. It requires no browser and is cheaper and faster than full-page scraping when you only need these specific link elements. Prefer it over generic scraping endpoints when your downstream pipeline expects Markdown-formatted output with a count.
Side effects
- URL is unreachable or returns a non-200 status — endpoint may return an empty list or error
- Page has no canonical or alternate elements — returns an empty Markdown list with a count of 0
- Malformed or relative URLs in the page's link elements may be returned as-is
- Pages with JavaScript-rendered metadata may be missed since no browser is used
- Rate limits or payment failures (x402) may block the request
