## 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-data-the-stall-x402-f7653611
```

Example prompt: Pull World Bank GDP data for the US, China, and Germany for the last 5 years — I want to see the trend and year-over-year changes for each country.

## When to prefer this

Use this endpoint when you need authoritative World Bank macroeconomic or development indicator data for one or more countries with trend history, formatted values, and YoY change — especially when you need named aliases (gdp, inflation, life_expectancy, etc.) rather than raw WB API codes. Prefer over manual World Bank API calls because it normalizes output and requires no API key, just a $0.003 USDC micropayment.

## Known failure modes

- Invalid or unsupported ISO country code returns empty or error series
- Unknown indicator alias or WB code returns error or empty result
- years parameter out of range (less than 1 or more than 10) fails schema validation
- World Bank upstream data unavailable or delayed returns stale or null values
- Payment not processed via x402 results in HTTP 402 rejection before data is returned
