# World Bank Country Data Bundle (GDP + Population)

> World Bank Country Data Bundle (GDP + Population) is a paid API for AI agents from agent402.tools, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Fetches GDP and population data for a given country from the World Bank in a single bundled API call using one x402 payment.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-bundle-gdp-population-4d0e5c8b -d '<json body>'
```

Example prompt: Can you pull the GDP and population figures for Japan from the World Bank in a single call using the country code JP?

## When to prefer this

Use this endpoint when you need both GDP and population data for a country simultaneously and want to avoid paying separately for multiple World Bank indicator calls — it bundles multiple indicators into one x402 payment, making it more cost-efficient than calling individual indicator endpoints.

## Known failure modes

- Invalid or unsupported ISO 3166-1 alpha-2 country code returns an error
- World Bank data unavailable for a specific country or indicator returns missing/null fields
- Payment failure via x402 protocol prevents execution
- Network timeout from upstream World Bank API

## How this service works

Bundled execution of the World Bank country data workflow - GDP and population for a country - two key World Bank indicators in one call. One x402 payment runs 3 underlying tools (world-bank-indicator, world-bank-indicator, world-bank-indicator); partial-success per step.

## Output

Returns GDP and population World Bank indicator values for the specified country, bundled from three underlying world-bank-indicator tool calls into a single response, covering key macroeconomic metrics.
