How this service works
Extract the page's canonical and alternates as csv: fetches the URL, pulls every canonical and alternates element and returns them as CSV rows, with a count. Structured, one-element-type extraction for agents and pipelines; no browser needed. $0.01 per page.
Output
A CSV-formatted response containing one row per canonical or alternate link element found on the fetched page, along with a count of total elements extracted. Each row represents a distinct canonical or alternate tag.
Example use cases
SEO canonical audit for a webpage
“Go to https://www.mysite.com/blog/post-1 and extract all the canonical and alternate link tags as a CSV so I can audit its SEO setup.”
Hreflang discovery for localization
“Fetch https://shop.example.com/products/widget and give me all the hreflang alternate URLs as a CSV — I need to see which language and region versions are declared.”
Duplicate content investigation
“I think https://news.example.com/article-123 might have a canonical pointing somewhere else — can you pull the canonical and alternate elements from that page as CSV rows so I can check?”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/page/canonical-and-alternates/csv?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured CSV output of canonical and alternate link elements specifically, without a browser or JavaScript rendering environment. Ideal for agent pipelines and SEO audit workflows that need machine-readable, row-per-element CSV data. Prefer over JSON or text variants when downstream tooling expects CSV format.
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- Page has no canonical or alternate elements — returns empty CSV with zero count
- URL parameter missing or malformed — request rejected
- Page blocks crawlers via robots.txt or firewall — fetch fails
- Payment of $0.01 USDC not completed — 402 response returned
