#time-series

Live historical foreign-exchange rates and analytics from the European Central Bank's daily reference rates — no key, nothing cached. Get the daily rate of a currency pair over any date range; the absolute and percentage move between two dates with its high and low; min, max, average, volatility and the best and worst day over a range; and every rate on a specific date. An FX history-and-analytics layer, distinct from spot-conversion feeds — it turns the ECB rate archive into the time series, moves and volatility a trader or analyst studies. Around 30 currencies, weekdays, back to 1999.

Economic data from 90+ official providers as one API, powered by DBnomics. DBnomics aggregates the public statistics of the IMF, OECD, Eurostat, the European Central Bank, the World Bank, the BIS, the US Federal Reserve and Bureau of Labor Statistics, national statistics offices and dozens more — millions of time series — into a single, consistent interface. List the data providers; search datasets across every provider at once by keyword; read a dataset's details and its dimensions (the codes you combine to pick a series); and fetch a series with its full observations (period and value) plus the latest data point. The typical flow is search → dataset → series. Ideal for macroeconomic and financial dashboards, data-science and research pipelines, fintech and economics apps, and anyone who needs GDP, inflation, unemployment, interest-rate, trade or monetary series from authoritative sources. Data is free and open.
