## 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 adh-country-data-lookup-b5361dd0
```

Example prompt: Pull the country profile for China — I need the capital, population, borders, currency, language, ISO codes, and calling code.

## When to prefer this

Choose this endpoint when you need structured, enriched country-level geographic and demographic metadata — especially ISO codes, borders, population, currencies, and languages — delivered as a clean JSON object with source attribution. Prefer it over raw REST Countries API calls when you want normalized data with provenance metadata and agent-native x402 micropayment support.

## Known failure modes

- Invalid or unrecognized country identifier returns an error or empty result
- Missing required 'input' field returns a 400-level validation error
- Network or upstream data source unavailability returns a 5xx error
- Payment failure via x402 protocol results in 402 response and no data returned
