How this service works
Paid public-data feeds. Unpaid requests return HTTP 402. Prices are USDC on Base.
Output
Returns a slim JSON object containing a time series array of country-level indicator data points (year and value pairs) from the World Bank v2 API, along with a uiLink pointing to the World Bank data portal page for the queried indicator and country.
Example use cases
Track poverty rates over time
“Get me the World Bank poverty headcount ratio data (indicator SI.POV.DDAY) for Nigeria (NGA) — I want the full time series to see how it has changed over the years.”
Compare CO2 emissions for a country
“Can you fetch the World Bank CO2 emissions indicator (EN.ATM.CO2E.PC) time series for China (CHN) so I can see how emissions per capita have trended historically?”
Monitor education enrollment statistics
“Pull the World Bank primary school enrollment indicator (SE.PRM.ENRR) for India (IND) — I need the historical time series data to analyze enrollment trends.”
Technical details
Endpoint
GEThttps://project-api-gamma-sable.vercel.app/paid/worldbank/indicator?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable World Bank indicator time series data for a specific country and indicator code, especially in an automated agent context where you can pay $0.01 USDC per call via x402. Prefer this over scraping the World Bank website or calling the World Bank API directly when you want a pre-processed slim JSON response with a UI link included.
Side effects
- HTTP 402 returned if payment in USDC on Base is not provided — caller must implement x402 payment protocol
- Invalid indicator code returns empty items array
- Invalid ISO3 country code may return empty results or an error
- Pagination out of range returns empty items
- World Bank upstream API unavailability causes downstream failure
