Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nager-date-available-countries-5559eb0a -d '<json body>'

Example prompt: What countries are supported by the Nager.Date holiday service? I need to see all the available country codes and names so I know which ones I can look up holidays for.

## When to prefer this

Use this endpoint when you need to discover which countries are supported before querying public holiday data, or when you need to validate a country code against the Nager.Date service's supported set. Prefer this over hardcoded country lists to stay in sync with what the holiday API actually supports.
