How this service works
Call when an agent needs hreflang attributes of //a via //a/@hreflang from a public page or HTML (SSRF-safe). Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/xpath-a-hreflang first.
Output
Returns a list of hreflang attribute values found across all anchor elements (//a/@hreflang) in the provided webpage or HTML, indicating the language and regional targeting of linked pages.
Example use cases
SEO i18n audit for a website
“Check https://www.shopify.com for all hreflang values in its anchor tags — I need to audit which language and region variants they're targeting in their links.”
Validate hreflang annotations in raw HTML
“I've got this HTML snippet from our CMS build — can you extract all the hreflang attributes from anchor elements to confirm we've set up our international targeting correctly?”
Competitive language-targeting research
“Go to https://www.booking.com and pull out every hreflang value from anchor tags on that page so I can see which locales they're serving alternate pages for.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-a-hreflang?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, paid, SSRF-safe extraction of hreflang attributes from anchor tags on a public URL or raw HTML. Prefer the free sandbox POST /v1/sandbox/xpath-a-hreflang first if available. Choose this over general-purpose scrapers when you specifically want XPath-targeted extraction of hreflang annotations without building your own parser.
Side effects
- URL is unreachable or returns a non-200 response — extraction fails with a fetch error
- HTML is malformed and XPath cannot parse any anchor elements — returns empty result
- No anchor tags with hreflang attributes exist on the page — returns an empty list
- URL exceeds 2048 characters or HTML exceeds 200,000 characters — rejected with validation error
- SSRF-blocked URL (private IP ranges, localhost) — rejected for security reasons
- Payment of $0.01 USDC not provided — request rejected with 402 Payment Required
