+## Usage Examples
+
+### Starting a Fake Voice Agent
+
+```javascript
+fetch('/fake-voice-agent/start', {
+  method: 'POST',
+  headers: {
+    'Content-Type': 'application/json',
+    'Authorization': 'Bearer YOUR_API_KEY'
+  },
+  body: JSON.stringify({ agentName: 'exampleAgent' })
+})
+.then(response => response.json())
+.then(data => {
+  console.log('Agent started:', data);
+  // Store the agent ID for future requests
+  const agentId = data.id;
+})
+.catch(error => console.error('Error:', error));
+```
+
+### Stopping a Fake Voice Agent
+
+```javascript
+fetch('/fake-voice-agent/stop', {
+  method: 'POST',
+  headers: {
+    'Content-Type': 'application/json',
+    'Authorization': 'Bearer YOUR_API_KEY'
+  },
+  body: JSON.stringify({ id: 'exampleAgentId' })
+})
+.then(response => response.json())
+.then(data => console.log('Agent stopped:', data))
+.catch(error => console.error('Error:', error));
+```
+
+### Checking Fake Voice Agent Status
+
+```javascript
+fetch('/fake-voice-agent/exampleAgentId/status', {
+  method: 'GET',
+  headers: {
+    'Authorization': 'Bearer YOUR_API_KEY'
+  }
+})
+.then(response => response.json())
+.then(data => console.log('Agent status:', data))
+.catch(error => console.error('Error:', error));
+```
+
+## Security
+
+All endpoints require authentication via a bearer token. Ensure your API key is included in the `Authorization` header for all requests.
+
+## Conclusion
+
+The Fake Voice Agent API provides a set of endpoints to simulate voice agent interactions. Use these endpoints for testing and development purposes.
+
+For more information on integrating voice agents into your applications, refer to the [Vapi Web SDK documentation](/quickstart/web) and [Vapi Server SDK documentation](/quickstart/server).

+# OpenAPI
+
+Vapi provides a comprehensive OpenAPI specification that describes our REST API endpoints, request/response schemas, and authentication requirements. This specification allows developers to easily integrate Vapi's voice AI capabilities into their applications.
+
+## Accessing the OpenAPI Specification
 
 <Check>
-  Our OpenAPI is hosted at
+  Our OpenAPI specification is hosted at:
   [https://api.vapi.ai/api-json](https://api.vapi.ai/api-json)
 </Check>
+
+You can use this URL to:
+
+- View the full API documentation
+- Generate client libraries in various programming languages
+- Test API endpoints directly from OpenAPI-compatible tools
+
+## Key Sections
+
+The OpenAPI specification includes details on:
+
+- Available endpoints and HTTP methods
+- Request parameters and body schemas  
+- Response formats and status codes
+- Authentication requirements
+- Available resources (Assistants, Calls, Phone Numbers, etc.)
+
+## Using with API Tools
+
+Many popular API development and testing tools support importing OpenAPI specifications. Some examples include:
+
+- Postman
+- Insomnia  
+- Swagger UI
+- Stoplight Studio
+
+Importing the Vapi OpenAPI spec into these tools allows you to quickly start exploring and testing our API endpoints.
+
+## Code Generation
