+### Dynamic Function Response
+
+You can provide a function that dynamically generates the response based on the incoming request:
+
+```javascript
+// Function response with access to the request object
+const tap = mock.taps.inject(
+  (request) => {
+    return {
+      response: {
+        message: `You requested ${request.url}`,
+        method: request.method,
+        timestamp: new Date().toISOString()
+      },
+      statusCode: 200,
+      headers: {
+        "X-Request-Path": request.url
+      }
+    };
+  },
+  { url: "/api/*" }
+);
+```
+
+```javascript
+// Conditional responses based on request
+const tap = mock.taps.inject((request) => {
+  // Return error for URLs containing 'error'
+  if (request.url.includes('error')) {
+    return {
+      response: { error: "Something went wrong" },
+      statusCode: 500
+    };
+  }
+
+  // Return success for everything else
+  return {
+    response: { status: "success" },
+    statusCode: 200
+  };
+});
+```
+
+```javascript
+// Dynamic headers based on request
+const tap = mock.taps.inject(
+  (request) => ({
+    response: "OK",
+    statusCode: 200,
+    headers: {
+      "X-Original-Method": request.method,
+      "X-Original-URL": request.url,
