Generally, you cannot use free services for sv_downloadurl / fastdl setups.
Most of them are already limited, and if you're occasionally finding one that doesn't limit it, it will only work for a very little while, and then they will block you from their service.
If you'd make a quick Googling or simple forum search for '000webhost', you would see that threads dating at least back to 2013 indicate that 000webhost does not allow this on their network.
