How this service works
Extract the page's canonical and alternates as json: fetches the URL, pulls every canonical and alternates element and returns them as a JSON array, with a count. Structured, one-element-type extraction for agents and pipelines; no browser needed. $0.01 per page.
Output
A JSON array containing all canonical and alternate link elements found on the fetched page, along with a count of how many elements were extracted. Each element in the array represents one canonical or alternate link tag parsed from the page's HTML.
Example use cases
SEO audit for canonical tags
“I need to check whether https://www.mysite.com/products/shoes has a canonical URL set and what alternate language versions are declared — can you pull those link elements as JSON?”
Hreflang inventory for localization
“Fetch https://www.globalshop.com/en/homepage and give me a JSON list of all the canonical and hreflang alternate links so I can see which language versions are being declared.”
Duplicate content check pipeline
“I'm building a pipeline to audit our site for duplicate content issues — can you extract the canonical and alternate elements from https://www.myblog.com/article/123 as JSON so I can feed it into my deduplication script?”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/page/canonical-and-alternates/json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, machine-readable JSON extraction of canonical and alternate link elements from a single web page without needing a browser. It is purpose-built for SEO metadata pipelines, hreflang audits, and canonical tag verification where you only need these specific link element types — not full page scraping or general metadata extraction.
Side effects
- URL is unreachable or returns a non-200 status — likely returns an error or empty result
- Page has no canonical or alternate link elements — returns an empty array with count 0
- URL is malformed or missing — request validation error
- Page blocks server-side fetching (e.g. requires JavaScript rendering) — may return incomplete results
- Payment not provided or insufficient — x402 payment required error
