+A wildcard can also appear before a file extension, and it matches at any depth. This is useful when static files and Function routes share a path, such as an API that serves pre-rendered `.json` files alongside routes handled by a Function.
+
+With the following `_routes.json`, `/api/users/1.json` and `/api/users/1/posts.json` are served as static assets without invoking the Function. `/api/users/1` and `/api/search` still invoke it.

+	"exclude": ["/api/*.json"]
+}

+
+This rule excludes every `.json` path under `/api/`, including any `.json` response your Function generates dynamically. For example, a request to `/api/export.json` will not reach your Function, even if no matching static file exists.

 If on the Workers Free plan, you can configure how Pages behaves when your daily free tier allowance of Pages Functions requests is exhausted. If, for example, you are performing authentication checks or other critical functionality in your Pages Functions, you may wish to disable your Pages project when the allowance is exhausted.
