Wasn't able to find a library or a Github or anything like that from a quick glance. I'm assuming this is a closed platform. What I was inquiring about was something that I can use in my own software.
You seem to have misunderstood the parent here. They are saying that at their company, they are doing this (_not_ as a library or product you can purchase).
Parent was saying that to implement it, they essentially wrote their REST API by grabbing a URL, dynamically creating a GraphQL query for it on their backend server, and then executing that query against their own GraphQL schema and returning the result.
