That API icon doesn't seem to be reliable.
I tried to withdraw 100+ csgo keys while it was red and I suceeded. In other cases some ppl added me, they couldn't pay to the bot with csgo keys, but we could trade between each other afterwards...
Withdrawal should work regardless of the API status, just that the change to the inventory won't be updated until the API is accessible.
Also, you can always trade with other people regardless of the API status, since you do not use the API trading with people.
It mainly affects deposit and purchase (since the API is used for backpack information).
