## 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 datanexusai-world-bank-country-economic-indicators-8f5f42ce
```

Example prompt: What is the GDP per capita for the United States according to World Bank data?

## When to prefer this

Choose this endpoint when you need structured World Bank economic indicator data (especially GDP per capita) for a specific country, delivered via a lightweight micropayment model. Prefer this over direct World Bank API access when you need a simple, agent-callable interface with predictable JSON output and x402 payment support. Best for one-off country lookups rather than bulk data pulls.

## Known failure modes

- Invalid or unrecognized country code returns an error or empty indicators object
- Payment failure (insufficient USDC balance or x402 misconfiguration) results in a 402 Payment Required response
- Network timeout if the upstream World Bank data source is unavailable
- Malformed path parameter (e.g., non-ISO country code) may return a 400 or 404 error

## How this service works

Public data API for SEBRA payments, PTP road accidents, Hearthstone cards, EU agri-food prices, and trade/market analytics. Paid data endpoints use x402 (USDC micropayments). Docs and discovery endpoints are free.

Machine-readable discovery: `https://api.datanexusai.org/openapi.json`, `https://api.datanexusai.org/llms.txt`, `https://api.datanexusai.org/.well-known/x402`.

## Output

A JSON object containing the country identifier, the endpoint name, and a nested indicators object with values such as GDP per capita (e.g., {"country":"USA","endpoint":"worldbank_country","indicators":{"gdp_per_capita":{"value":76329.6}}}).
