## 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 2s-io-f3c0897d
```

Example prompt: What are the capital, currency, official languages, and neighboring countries for Germany? Look it up using its ISO alpha2 code 'DE'.

## When to prefer this

Use this endpoint when you need comprehensive, structured country metadata in a single call — especially when you need ISO codes, currencies, languages, borders, timezones, and geographic details together. Prefer this over free-text web search when you need structured, machine-readable country data for enrichment, localization, or geopolitical workflows.

## Known failure modes

- Country not found for the given code or name — returns 404 or empty result
- Ambiguous partial name match when fullText=false returns unexpected country
- Invalid alpha2/alpha3 code returns error
- Missing required query parameter results in 400 bad request
- Payment not included or insufficient — returns 402 Payment Required

## How this service works

Look up country metadata via REST Countries. Pass alpha2 (2-letter ISO 3166-1), alpha3 (3-letter), or name (with optional fullText=true for exact match). Returns common + official name, ISO codes, region + subregion, independence + UN-member flags, capital(s), population, area km², landlocked flag, neighboring borders (alpha-3), timezones, currencies (code → name + symbol), languages, calling code, flag emoji + SVG/PNG URLs, lat/lng coordinates, Google Maps + OSM URLs, driving side, top-level domains.

## Output

Returns a rich country data object including common and official names, alpha2/alpha3 codes, region and subregion, independence and UN-member status, capital city or cities, population, area in km², landlocked flag, neighboring country codes (alpha3), timezones, currencies with code/name/symbol, languages, international calling code, flag emoji and SVG/PNG URLs, latitude/longitude coordinates, Google Maps and OpenStreetMap links, driving side, and top-level domains.
