## 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 language-tag-normalize-e97b406c -d '<json body>'
```

Example prompt: Normalize the language tag 'en_us' to its canonical BCP 47 form — fix the casing and separator so it's properly formatted.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use normalization of individual language tags without setting up a full i18n library. Ideal for agents handling user-submitted locale strings, data pipeline cleaning, or API integrations requiring strict BCP 47 compliance. At $0.01 USDC per call via x402, it suits low-to-moderate volume use cases where a hosted microservice is preferable to bundling a locale library.

## Known failure modes

- Invalid or unrecognizable language tag input returns an error
- Malformed input value (null, empty string, non-string) may return a validation error
- Network timeout or service unavailability on Render's free tier may cause 502/503 errors
- Payment failure via x402 protocol results in 402 Payment Required before processing

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output
