## 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-country-data-demographics-223268e8
```

Example prompt: Pull up the World Bank demographics for Nigeria — I want the population, 10-year growth rate, life expectancy, and internet usage percentage, plus whether it's classified as a growing or ageing population.

## When to prefer this

Use this endpoint when you need a quick, consolidated demographic snapshot — population size, growth trajectory, life expectancy, and internet penetration — for a single country, along with a machine-readable ageing/growing verdict. It is ideal for market research, investment screening, public health analysis, or any workflow that needs to characterize a country's demographic profile without building a multi-indicator query. Prefer it over general World Bank indicator endpoints when you want the opinionated verdict and summary pre-computed.

## Known failure modes

- Unknown or misspelled country name returns null or error
- Data may be degraded (degraded: true) if some indicators are unavailable for that country
- Some small territories may lack internet usage or life expectancy data, resulting in null fields
- ISO code vs full name disambiguation may produce unexpected country matches

## How this service works

Country demographics: population, 10-year population growth, life expectancy and internet use, with an ageing/growing verdict.

## Output

Returns a JSON object with the country name, ISO3 code, current population with year, 10-year annual growth percentage, life expectancy with year, internet users percentage with year, a verdict string (e.g. 'ageing' or 'growing'), a plain-language summary, supporting reasons, thresholds used for the verdict, data source URL, attribution, and any indicators not checked or data quality flags.
