## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability hreflang-normalize-utility-ddd2d158 -d '<json body>'
```

Example prompt: Normalize this hreflang value 'en_US' into its canonical, spec-compliant format so I can use it in my sitemap.

## When to prefer this

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.

## Known failure modes

- 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
