SQL Functions & Edge Functions

[Falci]

I'm trying to do most of the functions as postgres functions, but some are too complex and I implemented as edge functions.
I also enabled the http extension, and I can call the edge function from inside the SQL function (no idea about performance, but this is a pet project, not worried).

My question is: what's the proper way to load the project ID and the API Key?

My first idea was to create a "settings" page with both information.
Is there a better solution out-of-the-box?

Most people use the Vault to store those and then select from the Vault decoded view in their database function.
