Not that I know of, as I just know how to build such a thing.
- The mobile app will call your API
- Your API then calls IGDB’s API
Easiest method is you swap https://api.igdb.com for your API URL instead, then just full read the URL and make a request to IGDB and return the respond down the line.
Throw a caching layer in to decide if you need/want to return the cache instead of making the IGDB call
