Frequently asked questions
How often are rates updated?
The Frankfurter API mirrors the European Central Bank's daily reference rates, published once per business day around 16:00 Central European Time. Weekends and ECB holidays carry forward the prior business day's rate.
Is this really free?
Yes. The Frankfurter API is a free, open-source proxy in front of the ECB's published reference data. No API key, no rate limit, no signup. Mubboo proxies nothing — the call goes from your browser directly to Frankfurter's CDN.
What currencies are supported?
All currencies the ECB publishes against the euro — about 30, including USD, GBP, JPY, AUD, CAD, CHF, CNY, HKD, INR, MXN, SGD, BRL, ZAR, and the major European currencies. Cryptocurrencies are not included.
