## 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 x402stock-world-bank-macro-indicator-time-series-4e2658e9
```

Example prompt: Pull the World Bank inflation time series for Brazil for the last 15 years and tell me the latest value, what it was the prior year, and how much it changed.

## When to prefer this

Choose this endpoint when you need structured, annual macroeconomic time series data for a specific country sourced from the World Bank — particularly for indicators like GDP, inflation, unemployment, population, government debt, exports, FDI, or current account balance. It is ideal for cross-country macro reference, economic research, risk analysis, or populating dashboards with authoritative development statistics. Prefer it over proprietary data sources when open, citable World Bank data (CC BY 4.0) is required.

## Known failure modes

- Invalid indicator slug returns a 404 or error response
- Invalid or unsupported country code returns an error
- Limit exceeding the maximum of 66 or set to 0 triggers a validation error
- World Bank data may have gaps for certain country-indicator combinations, resulting in null values
- Payment failure (insufficient USDC balance) results in a 402 Payment Required response
