GDP Growth API
How fast each economy is actually growing, on one comparable screen — real GDP growth from the OECD's official Quarterly National Accounts as an API, live, no key. Real GDP growth is the single most-watched macroeconomic number there is: it is the headline measure of whether an economy is expanding or in recession, it sets the backdrop for every central-bank decision, and the quarterly print moves bond, currency and equity markets. The OECD harmonises and seasonally adjusts the national accounts so the figures are genuinely comparable across countries. This API serves the two growth rates people actually quote — the quarter-on-quarter change (the latest quarter's pace) and the year-on-year change (growth versus the same quarter a year earlier), both for real, chain-linked-volume GDP. The board endpoint ranks every economy by its year-on-year growth, with the quarter-on-quarter move alongside, so you can see who is booming and who is shrinking. The momentum endpoint ranks by the latest quarter-on-quarter move — the freshest read on the cycle. The country endpoint gives one economy's GDP growth with a plain-language read (two consecutive negative quarters is the classic technical-recession marker). Each reading carries its own quarter and discontinued series are excluded, so the board is genuinely current. The headline GDP-growth cut — distinct from the annual IMF World Economic Outlook database (a yearly figure and forecast, not the live quarterly print), the leading-indicator and confidence boards (forward-looking soft data), and the generic multi-provider data aggregator. Figures are quarterly, in percent.
