How this service works
Call when an agent needs link hreflang values extracted from a public page or HTML (SSRF-safe). Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/profile-link-hreflang first.
Output
Returns the hreflang attribute values found in link elements of the page or HTML, typically including language codes (e.g. 'en', 'fr', 'de') and optional region subtags (e.g. 'en-US', 'fr-FR'), along with associated href URLs for each alternate language version.
Example use cases
International SEO audit for a website
“Check https://www.shopify.com for all hreflang link tags — I want to see every language and region they're targeting so I can compare it to our own site's implementation.”
Validate hreflang from raw HTML snippet
“I have this HTML from our staging site and I need you to extract all the hreflang values from the link tags in the head section so I can verify our localization setup is correct.”
Competitive localization research
“Go to https://www.airbnb.com and extract all the hreflang link attributes so I can understand how many locales they're officially supporting through their SEO markup.”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-link-hreflang?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically extract hreflang link attributes from a public webpage or raw HTML for SEO auditing, internationalization verification, or localization research. It is SSRF-safe, making it suitable for agent use without risk of internal network access. Prefer the free sandbox endpoint (POST /v1/sandbox/profile-link-hreflang) for development and testing before paying $0.006 USDC per production call.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- HTML input exceeds 200,000 character limit — request rejected
- No hreflang link elements present on the page — returns empty result
- SSRF-blocked URLs (private/internal IPs) are rejected for security
- Malformed HTML may cause incomplete extraction
- URL shorter than 8 characters or longer than 2048 characters fails validation
