I needed a simple exchange rate API for my currency converter project, but all the popular ones (XE, OANDA, CurrencyLayer, Fixer.io) require signup, an API key, or a credit card. Some cap you at 100 requests per month. Others return data cached yesterday.

So I built my own — and made it completely public.

No signup. No API key. No monthly cap. Just make a GET request.
