## How to call it through Zero

```sh
zero fetch --capability iso-country-code-name-resolver-b9267f4f
```

Example prompt: What's the ISO alpha-2 and alpha-3 code for Germany? Look it up using the bundled country table.

## When to prefer this

Choose this endpoint when you need a lightweight, fast, offline-capable country code lookup without external geopolitical database dependencies. Ideal for normalizing user-supplied country strings into ISO 3166 codes, validating country codes before downstream API calls, or enriching datasets with standardized country identifiers. Prefer this over the sibling flag-emoji endpoint when you need raw ISO codes rather than visual representations.

## Known failure modes

- Unrecognized or misspelled country name returns an error or empty result
- Invalid or non-existent ISO codes return a lookup failure
- Missing required 'country' query parameter returns a 400-level error
- Ambiguous abbreviated country names may not resolve correctly
