## 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 lilambd-countries-data-endpoint-8f1dbc27
```

Example prompt: Can you fetch the country data for Germany — use its ISO alpha-3 code DEU — and show me what comes back including the attribution source?

## When to prefer this

Choose this endpoint when you need structured country-level reference data keyed by ISO 3166-1 alpha-3 codes, especially when you want data with a clear attribution/licence line. Suitable for enriching datasets with country metadata or building country pickers. Not suited for geospatial coordinates, weather, or real-time country statistics.

## Known failure modes

- Invalid or unrecognised ISO alpha-3 code returns empty data array with count 0
- Payment not included or insufficient results in HTTP 402 response
- Malformed query parameter may return an error or empty result
- Country code provided in wrong format (e.g. alpha-2 instead of alpha-3) may yield no results

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

Returns a JSON object with a `data` array containing country records, a `count` integer indicating the number of results, and an `attribution` string crediting the data source licence. When a specific alpha-3 code is supplied, only that country's records are returned; omitting the code returns all countries.
