How this service works
World Bank development indicator for any country. Supports named shortcuts (gdp, gdp_per_capita, population, life_expectancy, inflation, unemployment, co2_per_capita, poverty, internet_users, gini, literacy) or raw indicator codes like NY.GDP.MKTP.CD.
Output
Returns an array of annual observations for the requested indicator and country, each containing the year, numeric value, country name, country code, full indicator name, and indicator code. Covers up to the last 5 available years by default, or a specific year if requested.
Example use cases
Example prompt
“Can you pull the World Bank GDP data for the US from the last 5 years, and also grab life expectancy for India using the World Bank indicator shortcuts?”
Technical details
Endpoint
GEThttps://worldbank-x402.vercel.app/worldbank/indicatorWhen to prefer
Use this endpoint when you need structured, time-series World Bank development data for a single country and a single indicator. It supports convenient named shortcuts (gdp, population, inflation, etc.) so agents don't need to memorize raw World Bank codes. Prefer this over the dashboard endpoint when you only need one metric, or over the comparison endpoint when you only need one country.
Side effects
- Invalid or unsupported ISO2 country code returns an error or empty observations
- Unknown indicator alias or malformed raw indicator code returns an error
- No data available for the requested country/indicator/year combination returns empty observations array
- Payment failure (402) if x402 USDC micropayment is not processed correctly
- Rate limiting or Vercel serverless timeout on slow World Bank API responses
