How this service works
Machine-callable x402-paid utilities for autonomous agents.
Output
A JSON object containing the normalized, canonical hreflang string and the operation name ('hreflang_normalize'), confirming the corrected language-region tag ready for use in HTML or sitemaps.
Example use cases
Multilingual sitemap hreflang cleanup
“I have a list of hreflang values like 'en_US', 'zh_TW', and 'pt_BR' in my sitemap — can you normalize each one to the correct BCP 47 canonical format?”
International SEO audit fix
“During our SEO audit we found malformed hreflang tags like 'EN-us' and 'ZH-hans-cn' — normalize them to the proper canonical form so we can fix the site.”
CMS locale code standardization
“Our CMS stores locale codes like 'english_united_states' and I need them converted to valid hreflang attribute values before publishing the international pages.”
Technical details
Endpoint
POSThttps://creator-desk-x402-isolated.onrender.com/v1/utility/hreflang-normalize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic, per-call normalization of hreflang or locale strings as part of an automated SEO pipeline, sitemap generation, or CMS publishing workflow — especially when paying per-call via x402 is acceptable and you need a lightweight, stateless utility without standing up your own normalization library.
Side effects
- Invalid or unrecognizable locale string returns an error result
- Malformed input that cannot be mapped to any known language tag may return null or an error
- Network timeout if the Render.com server is cold-starting
- Missing 'value' field in request body may cause a 400-level error
