Fixer.io provides daily rates. The API is fast, free, reliable, and requires no API key. There seems to be no effective rate limit.

Fixer.io is a free JSON API for current and historical foreign exchange rates published by the European Central Bank.
The rates are updated daily around 3PM CET.
zerohedge had an article a few weeks ago about how the USDCNY has been a 30 minute lead indicator for BTCUSD.
I was wondering if there were any sites out there that provided free 1m FX.
After running fixer.io now live on 1h for a week I can report that it is not reliable from 8AM to 2PM EST. Otherwise I get clean hourly updates the rest of the day.
