How this service works
Real Interest Rate for any country by ISO code as a yearly World Bank Open Data time series, no key. Returns country, year, and value. For AI agents doing macro, demographic, and cross country analysis.
Output
Returns a time series array for the specified country with each record containing the country identifier, year, and the real interest rate value as reported by the World Bank. Coverage spans multiple decades depending on data availability for the given ISO code.
Example use cases

“Get me the real interest rate time series from the World Bank for Turkey, Brazil, and South Africa — I need yearly data so I can compare emerging market borrowing conditions over the past 20 years.”
Cross-country investment climate report
“What has Germany's real interest rate looked like year by year over the last decade? Pull the World Bank data for DE so I can include it in a report on European investment climate.”
Demographic and growth correlation study
“I'm building a model that correlates real interest rates with GDP growth — can you fetch the World Bank real interest rate time series for the United States, China, and India using their ISO codes?”
Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-wb-real-interest-rateWhen to prefer
Choose this endpoint when you need authoritative, long-run yearly real interest rate data sourced directly from the World Bank without managing your own API key. It is ideal for macroeconomic, cross-country, or demographic analyses where consistent World Bank methodology matters. Prefer it over scraping or general web search when you need structured, machine-readable time series data for a specific country by ISO code.
Side effects
- Invalid or unrecognized ISO country code returns an error or empty dataset
- Country has no World Bank real interest rate data for requested years — returns empty series
- World Bank upstream data source unavailable — endpoint returns degraded or error response
- Malformed POST body or missing required fields returns a 400-level error
- Payment failure via x402 protocol blocks the request before data is returned
