fetch
Fetches the schemeful site for a specific origin.
Note: this function uses an input class, and constructing this class manually may lead to incompatibilities if the class's constructor arguments change in the future. For maximum compatibility, it is advised to use the overload of this function that directly takes the mandatory parameters as arguments, and the optional ones from a configuration lambda.
