How this service works
Call when an agent needs anchor hreflang values extracted from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/profile-a-hreflang first.
Output
A list of hreflang attribute values extracted from anchor elements on the specified page or HTML, representing language and region codes (e.g. 'en-US', 'fr-FR', 'x-default') along with their associated URLs, enabling analysis of a page's international SEO link annotations.
Example use cases
Multilingual SEO audit for a website
“Pull all the hreflang tags from https://shop.acme.com/products — I want to know which language and country variants they've declared for that page.”
Verify alternate language links in HTML
“Here's the raw HTML of our homepage — can you extract all the hreflang attribute values from the anchor tags so I can check our international link setup is correct?”
Competitor internationalization research
“Check https://competitor.com/pricing and tell me all the hreflang values they use — I want to see which locales they're targeting with alternate language pages.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-a-hreflang?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically extract hreflang alternate language annotations from a live webpage or known HTML for SEO auditing, internationalization verification, or competitor research. It is SSRF-safe, making it appropriate for agent pipelines that fetch arbitrary user-supplied URLs. Prefer the free sandbox endpoint (/v1/sandbox/profile-a-hreflang) for testing before committing to the $0.002 USDC paid call.
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- HTML input exceeds 200,000 character limit — request rejected
- URL is blocked for SSRF safety reasons (private/internal IP ranges) — returns an SSRF error
- Page contains no anchor hreflang attributes — returns an empty result set
- Malformed HTML prevents proper parsing — partial or empty results
- URL string is shorter than 8 characters or longer than 2048 characters — validation error
