## 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 iso-3166-1-country-lookup-by-code-or-name-91f4cb4c -d '<json body>'
```

Example prompt: What are all the ISO 3166-1 codes and UN region for the country with alpha-2 code 'DE'?

## When to prefer this

Use this endpoint when you have an exact ISO 3166-1 code or the precise English country name and need to retrieve the full set of ISO codes plus the UN region. For fuzzy or partial name matching, prefer the /v1/search sibling endpoint instead.

## Known failure modes

- No match found if the provided name or code does not exactly match (use /v1/search for fuzzy matching)
- Error if more than one field is provided simultaneously
- Error if the input field value is malformed or empty
- Invalid body type returns a validation error

## How this service works

Look up a country by its ISO 3166-1 alpha-2 code, alpha-3 code, numeric code or English name. Provide exactly one field. Returns all codes plus the UN region.

## Output

Returns a country object containing the ISO 3166-1 alpha-2 code, alpha-3 code, numeric code, English country name, and UN region classification.
