Data
Reference tables and datasets built from public sources, with the source and date on every page.
Each page here is a table you can read, cite and download: the data comes from official open sources, every figure is dated, and the same facts are available through the API for programs and AI agents. Use the tables when you need the numbers once; use the tools when you need them inside a workflow. New tables are added when a dataset is requested often enough to be worth keeping up to date.
ECB year-end exchange rates
