## 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 clonecho-population-ages-65-and-above-db68cf1c -d '<json body>'
```

Example prompt: Can you pull up the latest data on what percentage of each country's population is aged 65 and above? I want to compare aging demographics across nations.

## When to prefer this

Use this endpoint when you need a quick, no-parameter global snapshot of elderly population shares (65+) across all countries, for demographic analysis, country comparison, or enriching a dataset with aging statistics. Prefer it over general World Bank APIs when you want a flat, ready-to-use JSON payload without query complexity.

## Known failure modes

- Payment not sent or insufficient USDC balance — 402 Payment Required
- Upstream data source unavailable — 503 or timeout
- Malformed response if data pipeline fails — partial or empty JSON
- Rate limiting if too many calls in a short window
