CPI Inflation Rate API

The headline consumer-price inflation print for every major economy, broken into its core and its drivers, live from the OECD's official price statistics — no key. Consumer-price inflation is the single most-watched macro number on earth: the gauge every central bank targets, the thing that sets the real value of wages, debts and savings, and a number whose surprises move bonds, currencies and equities within seconds. This API serves the year-on-year national CPI the way it is actually reported, for ~50 economies — and crucially it does not stop at the headline. For each economy it also serves the core rate (all items excluding food and energy, the measure policymakers really steer by), plus the food, energy and services rates themselves. That decomposition tells you whether a reading is a temporary food/energy shock or a stickier, demand-driven core problem: headline above core means volatile food/energy are pushing prices up; headline below core means they are dragging the print down while underlying inflation stays hot. The board endpoint ranks economies by headline inflation with core alongside; core ranks by the core rate; country gives one economy's full breakdown with the headline-vs-core read. Each reading carries its own month and discontinued series are filtered out, so the board is genuinely current. This is the realised-inflation cut — distinct from the inflation calculator (arithmetic from a rate you supply, not live data), from consumer inflation expectations (a survey of what households think prices will do, not what they did), and from unit labour costs and wages. Rates are percent year-on-year; figures are monthly.
