## 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 age-dependency-ratio-by-country-6db0f831 -d '<json body>'
```

Example prompt: Can you pull up the latest age dependency ratio for every country — I want to see which nations have the highest share of dependents relative to their working-age population?

## When to prefer this

Use this endpoint when you need a ready-to-use, pre-fetched global snapshot of age dependency ratios without setting up a World Bank API key or writing custom data-fetch logic. Ideal for quick demographic comparisons, economic modeling inputs, or enriching country-level datasets with dependency burden metrics.

## Known failure modes

- Payment failure if USDC balance or x402 authorization is insufficient (402 response)
- Data may lag by 1-2 years depending on World Bank release cycle
- No country-level filtering — always returns full global dataset

## How this service works

## Output

A JSON object containing one record per country with the country name/code and its latest age dependency ratio expressed as a percentage of the working-age population (ages 15–64).
