How this service works
The rel="alternate" links of a page: every matching <link>/<a> with href, resolved to absolute URLs, with a count. Language/format alternates. $0.01 per page.
Output
A list of all <link> and <a> elements with rel="alternate" found on the target page, each resolved to an absolute URL, along with a total count of matching links. Typical results include hreflang entries for different language/region versions and format alternates such as RSS, Atom, AMP, or PDF representations.
Example use cases
Multilingual site language discovery
“Check https://www.bbc.com/news and give me all the alternate language versions it links to — I want the full absolute URLs for each language variant declared on that page.”
RSS and feed link detection
“Does https://techcrunch.com declare any RSS or Atom feed alternates in its link tags? Fetch the rel=alternate links and show me what it finds.”
SEO hreflang audit
“I need to audit the hreflang setup on https://www.shopify.com — can you grab all the rel=alternate links so I can verify every language and region variant is properly declared?”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/link-rel/alternate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to discover language alternates (hreflang), format alternates (RSS, AMP, PDF), or other rel=alternate link annotations declared in a page's HTML. It is preferable over a full-page scrape when you only need alternate link metadata and want a focused, low-cost extraction. Choose this over generic link extractors when the rel attribute type matters and you want resolved absolute URLs ready to use.
Side effects
- Page returns non-200 status — no links extracted
- Page has no rel=alternate links — returns empty list with count 0
- Relative URLs that cannot be resolved if base URL is ambiguous
- JavaScript-rendered pages may not expose alternate links if only rendered client-side
- Rate limiting or access restrictions on the target page returning an error
- Invalid or malformed URL input causing request failure
