## 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 suverse-countries-capitals-directory-be36d0b4 -d '<json body>'
```

Example prompt: Give me the full list of all countries in the world along with their capital cities and ISO2 and ISO3 country codes.

## When to prefer this

Use this endpoint when you need a single, complete, no-key-required reference list of all world countries with capital cities and ISO codes. Ideal for populating dropdowns, building lookup tables, or enriching datasets without needing to set up a credentials-based geography API. Prefer over full geography APIs when you only need the country/capital/code reference data and want a simple one-call solution.

## Known failure modes

- Upstream countriesnow.space API unavailability causes proxy failure
- Payment not received or x402 flow incomplete results in 402 response
- Malformed POST body may return a 400 error
- Occasional stale or outdated capital city data if upstream source is not refreshed

## How this service works

Get a complete directory of all countries with their capital cities and ISO2/ISO3 codes. Single call returns the full list. Free countriesnow.space data, no key required. Ideal for reference tables and enrichment.

## Output

A complete list of all world countries, each entry containing the country name, its capital city, and both ISO2 (2-letter) and ISO3 (3-letter) country codes. Returned as a single response with no pagination required.
