Hey, guys. I need to fetch current courses of popular cryptocurrencies at random times, but frequently.

I checked Chainlink Data Feeds, which looks really good, but it updates courses, whether when the course moves more than deviation threshold or 3600 seconds have passed since last update. 3600 seconds is an interval for BTC and ETH. That's too much for my needs. On other hand BNB has only 60 seconds of refresh late, which is good for me.

So my only solution is to use Provable (Oraclize) and request courses using API of some crypto market?
