The OECD Data API gives the statistics of the OECD's member countries, such as GDP growth, inflation, employment, education and environment indicators, for example to compare countries in a report. It is an SDMX REST API: build a query from a dataflow and filters, and get SDMX-JSON, SDMX-ML (XML) or CSV. Free, no key needed; the OECD limits how many queries one user may send per hour.
