Thanks for reaching out to Q&A.
You can try this url : https://management.azure.com/subscriptions/subscriptionid/resourceGroups/resourcegroupname/providers/Microsoft.Web/sites/sitename/hostruntime/admin/vfs/proxies.json?relativePath=1&api-version=2018-11-01
You could also write custom code that calls the VFS API to get proxies.json and parse the rules from there.

Please note that we have removed Proxies support in Functions v4 as there is an APIM Consumption tier now .
“Azure Functions Proxies are no longer supported in 4.x. You are recommended to use Azure API Management.”
I hope this helps!
