Help with VPN outbound traffic

I see lots of posts about setting up VPN for connecting back into HA but what I’m trying to do is connect HA to a VPN server so the outbound traffic is not from my IP address.

I have an integration that talks to a API but if there’s too many requests it blocks you for a day so ideally I’d like to split my traffic between my WAN IP address and a VPN IP address.

Anyone know how I can achieve this?

Usually, those limitations are set based upon an API key. Sure it’s based on IP?

It seems to be IP related.

If i refresh the service on my phone using wifi and get a message saying too many requests and i switch to 4G and try again it work because my IP is different.
