## 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 countrylayer-eu-regional-bloc-country-lookup-69a1ab92
```

Example prompt: Can you give me a list of all the countries that are part of the EU regional bloc, including their country codes and basic details?

## When to prefer this

Use this endpoint when you need a complete, structured list of all EU member countries with rich metadata (codes, population, languages, currencies). Prefer this over a general country list endpoint when you specifically need to filter by regional bloc membership rather than querying individual countries.

## Known failure modes

- Invalid or unrecognized regional bloc code returns empty or error response
- API key missing or invalid returns 401 unauthorized
- Payment not completed returns 402 payment required
- Rate limit exceeded returns 429 too many requests
- Service unavailable returns 503

## How this service works

Countries by regional bloc: append /{bloc}.

## Output

A list of countries that are members of the EU regional bloc, each with metadata such as country name, ISO codes, capital city, region, subregion, population, area, currencies, and languages — sourced from countrylayer.
