How this service works
Annual time series of one World Bank indicator for a country, with latest value, prior year, and change. Indicators: gdp, gdp-growth, gdp-per-capita, inflation, unemployment, population, govt-debt, current-account, exports, fdi. Pick the country with `?country=US` (ISO2/ISO3, default US) and the span with `?limit=` years (default 10). Cross-country macro reference. Source: World Bank (CC BY 4.0).
Output
A JSON object containing the indicator slug and full World Bank indicator code and name, country code and name, the latest available year and value, the prior year and value, absolute and percent change, a full array of annual {year, value} history entries up to the requested limit, a source tag ('world_bank'), an as_of date, last_updated timestamp, and a CC BY 4.0 attribution string.

Endpoint
GEThttps://agents.x402stock.xyz/api/v1/world-bank/{indicator}When to prefer
Use this endpoint when you need structured, World Bank-sourced annual macro data for a specific country and indicator, including year-over-year change context. It is preferred over raw World Bank API calls because it normalises the response into a consistent schema with latest/prior/change fields pre-computed, supports simple indicator slug names (e.g. 'gdp' instead of 'NY.GDP.MKTP.CD'), and is accessible pay-per-call without API keys. It covers cross-country reference for 10 named macro indicators spanning GDP, inflation, unemployment, population, debt, trade, FDI, and more.
Side effects
- Unknown indicator slug returns a 404 or error response
- Invalid or unrecognized country code returns an error
- World Bank data may have a 1-2 year lag so 'latest' may not be the current calendar year
- Some country-indicator combinations have sparse or missing data, resulting in null values in history
- limit values outside the allowed range (1–66) return a validation error
