How this service works
Call when an agent needs hreflang attributes of //link via //link/@hreflang from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/xpath-link-hreflang first.
Output
A list of hreflang attribute values extracted from all <link> elements on the given page or HTML, typically returning language-region codes such as 'en', 'fr-FR', 'x-default', etc., paired with any associated href values.
Example use cases
International SEO audit for a website
“Check https://www.acme.com/products and pull out all the hreflang link attributes so I can audit which language and country alternates they've declared for international SEO.”
Verify hreflang before publishing
“I've got this HTML for a new landing page — can you extract the hreflang values from all the link tags to confirm the correct language variants are set before we go live?”
Compare locale coverage across pages
“Pull the hreflang link attributes from https://shop.globalstore.com/fr/accueil so I can see which locale codes are listed and check if any regions are missing.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-link-hreflang?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to extract hreflang attributes from <link> elements on a page for internationalization auditing, SEO analysis, or locale coverage verification. It is SSRF-safe and accepts either a live URL or raw HTML. Prefer the free sandbox POST /v1/sandbox/xpath-link-hreflang first; use this paid endpoint when you need production reliability or the sandbox is unavailable.
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- HTML input is empty or missing valid <link> elements — returns empty list
- URL triggers SSRF protection — blocked by safety filter
- HTML exceeds 200,000 character limit — request rejected
- No hreflang attributes present in any link elements — returns empty result
- Malformed HTML may cause incomplete parsing
