May I ask about api key?

I need to use an open api now, but this api needs a key for verification, and I need to fill in an ip. My interface to access the api directly at the front end is 403, so I wonder if I need a server to transfer and there is no way to solve the key problem directly at the front end?

api also makes a distinction. For those with high security and less frequent access, the server does need to transfer. If you need to specify an ip address in the api configuration, it should be like this.
