## 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 selectarank-data-gateway-world-bank-indicator-lookup-43ab353a
```

Example prompt: Pull the World Bank GDP per capita indicator (NY.GDP.PCAP.CD) for India — I want the latest available data and I'm happy to pay the $0.002 per call fee.

## When to prefer this

Choose this endpoint when you need World Bank development indicator data on demand without setting up an account or API key, and when paying $0.002 USDC per call via x402 micropayment on Base is acceptable. Ideal for agents that need occasional lookups of macroeconomic, social, or development statistics by country and indicator code without a long-term API subscription.

## Known failure modes

- Invalid country code returns empty data array or 404
- Invalid indicator code returns empty data array
- Payment not received or x402 payment check fails — returns 402 Payment Required
- World Bank upstream API unavailable — returns 503 or empty data
- Malformed URL parameters return 400 Bad Request

## How this service works

Pay-per-call access to public-domain data (USGS earthquakes, NOAA/NWS forecasts, World Bank indicators) plus an x402 endpoint pre-payment checker over x402 on Base USDC. No account or API key.

## Output

Returns a JSON object with a 'data' array containing World Bank time-series indicator values for the specified country and indicator, plus a 'meta' object with source attribution (e.g. {source: 'World Bank'}). The data array typically includes year-by-year entries for the requested indicator.
