 This article explains how to configure and work with Azure Functions Proxies. With this feature, you can specify endpoints on your function app that are implemented by another resource. You can use these proxies to break a large API into multiple function apps (as in a microservice architecture), while still presenting a single API surface for clients.
 
+Standard Functions billing applies to proxy executions. For more information, see [Azure Functions pricing](https://azure.microsoft.com/pricing/details/functions/).

It provides the same capabilities as Functions Proxies as well as other tools for building and maintaining APIs, such as OpenAPI integration, rate limiting, and advanced policies.
