Big Mac Index API
The Economist's Big Mac Index — "burgernomics" — as an API: how over- or under-valued the world's currencies are, measured by the price of a Big Mac. The same burger costing different amounts across countries reveals purchasing-power-parity (PPP) misalignment in exchange rates. The index endpoint returns the latest release for every country — the local Big Mac price, its US-dollar price at the market exchange rate, and the raw and GDP-adjusted over/under-valuation of that currency against a chosen base (USD, EUR, GBP, JPY or CNY). The country endpoint returns one country's full history — the valuation trend over every release since 2000. The extremes endpoint returns the most over-valued and most under-valued currencies in the latest release. A positive valuation means the currency is over-valued versus the base; negative means under-valued; the GDP-adjusted figure corrects for cheaper labour in poorer countries. This is a PPP / currency-valuation data-cut — a fundamental gauge, not a live FX tick — distinct from the spot-rate, central-bank and conversion APIs in the catalogue. Live from the open dataset, no key on the upstream, nothing stored.
