API GET Whitelist Firewall

Hello how are you? I’m from Brazil and I’m having a problem, because I would need exactly a fixed bubble IP, so that a GET reaches my server’s database safely through a whitelist, and I saw that someone came up with the idea of ​​doing this with AWS. Someone got this? Would someone be available to help me with this service? Thank you very much for now. If someone have any offers, we look forward to it.

Hi, Did you manage to resolve this?
