Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-macro-cpi-inflationWhen to prefer
Choose this endpoint when you need authoritative, World Bank-sourced annual CPI inflation data for any country by ISO code, especially for macroeconomic analysis, real return calculations, inflation regime identification, or monetary policy context. Prefer this over general economic APIs when you specifically need a clean yearly time series of consumer price inflation backed by World Bank methodology.
Side effects
- Invalid or unrecognized ISO country code returns an error or empty result
- Country has no World Bank CPI data for certain years, resulting in null values in the time series
- World Bank upstream data unavailable or stale, causing degraded or cached response
- Malformed POST body or missing required fields returns a 400-level error
- Payment failure (x402) if the $0.004 USDC micropayment is not correctly processed
