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.
Example use cases
Country economic comparison research
“Get me the World Bank GDP per capita indicator NY.GDP.PCAP.CD for Brazil so I can compare it with other emerging markets — go ahead and pay the small fee per call.”
Development report data enrichment
“I'm building a development report and need the World Bank poverty headcount ratio indicator SI.POV.DDAY for Kenya — fetch the data and include whatever metadata comes back about the source.”
Education statistics retrieval
“Look up the World Bank primary school enrollment indicator SE.PRM.ENRR for India — I need the time-series values to track educational progress over the years.”

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.
