## 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 country-code-converter-iso-3166-1-alpha-2-alpha-3-numeric-metadata-5e72e405
```

Example prompt: Can you convert the country code 'DEU' and give me back the alpha-2 code, numeric code, currency, ccTLD, and calling code for that country?

## When to prefer this

Use this endpoint when you need to convert between ISO 3166-1 code formats (alpha-2 ↔ alpha-3 ↔ numeric) or retrieve standard country metadata like currency, ccTLD, or calling code from a known ISO code. Prefer this over the fuzzy-match or name-normalization sibling endpoints when you already have a valid ISO code and need a precise, structured conversion rather than name resolution or search.

## Known failure modes

- Invalid or unrecognized country code returns a non-match or error result
- Ambiguous numeric codes may resolve to unexpected countries if input format is unclear
- Payment failure (402) if USDC balance is insufficient
- Rate limiting or service unavailability returning 5xx errors
- Deleted or reserved ISO codes may return degraded or partial results

## How this service works

Convert an ISO 3166-1 country code between alpha-2, alpha-3 and numeric; also name, currency, ccTLD, calling code.

## Output

Returns a structured object containing the matched country's alpha-2, alpha-3, and numeric codes, official and common name, currency code(s), ccTLD, calling code(s), region, sub-region, capital, and independence status. A summary and attribution are also included. The `to` parameter lets you filter down to only the specific field type you need.
