To clear things up, it was off for like 1-2 days, I also noticed, since I use coinmarketcap api to manage my portfolio, it returned error requests. Now it's fine again.
Can you share a snippet of how you use the API? I'm trying to use Excel and its acting fubar for me. If you can show your snipped for one currency, I can pretty much make it work for the other 200 currencies I'm invested in.
