## 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 world-bank-death-rate-time-series-by-country-653f4b2f -d '<json body>'
```

Example prompt: Pull the full yearly death rate per 1,000 people time series from the World Bank for Japan — I need to see how mortality has trended over the decades.

- Invalid or unrecognized ISO country code returns an error or empty dataset
- Country has incomplete World Bank data for certain years, resulting in null values in the series
- Service unavailable returns a 402 or 5xx error
