+# Single Agent Sample (Python)
+
+This sample demonstrates how to use the Durable Extension for Agent Framework to create a simple Azure Functions app that hosts a single AI agent and provides direct HTTP API access for interactive conversations.
+
+## Key Concepts Demonstrated
+
+- Defining a simple agent with the Microsoft Agent Framework and wiring it into
+  an Azure Functions app via the Durable Extension for Agent Framework.
+- Calling the agent through generated HTTP endpoints (`/api/agents/Joker/run`).
+- Managing conversation state with thread identifiers, so multiple clients can
+  interact with the agent concurrently without sharing context.
+
+## Prerequisites
+
+Follow the common setup steps in `../README.md` to install tooling, configure Azure OpenAI credentials, and install the Python dependencies for this sample.
+
+## Running the Sample
+
+Send a prompt to the Joker agent:
+
+Bash (Linux/macOS/WSL):
+
+```bash
+curl -i -X POST http://localhost:7071/api/agents/Joker/run \
+     -d "Tell me a short joke about cloud computing."
+```
+
+PowerShell:
+
+```powershell
+Invoke-RestMethod -Method Post -Uri http://localhost:7071/api/agents/Joker/run `
+    -Body "Tell me a short joke about cloud computing."
+```
+
+The agent responds with a JSON payload that includes the generated joke.
+
+> [!TIP]
+> To return immediately with an HTTP 202 response instead of waiting for the agent output, set the `x-ms-wait-for-response` header or include `"wait_for_response": false` in the request body. The default behavior waits for the response.
+
+## Expected Output
+
+The default plain-text response looks like the following:
+
+```http
+HTTP/1.1 200 OK
+Content-Type: text/plain; charset=utf-8
+x-ms-thread-id: 4f205157170244bfbd80209df383757e
+
+```
+
+When you specify the `x-ms-wait-for-response` header or include `"wait_for_response": false` in the request body, the Functions host responds with an HTTP 202 and queues the request to run in the background. A typical response body looks like the following:
+
+```json
+{
+  "status": "accepted",
+  "response": "Agent request accepted",
+  "message": "Tell me a short joke about cloud computing.",
+  "thread_id": "<guid>",
+  "correlation_id": "<guid>"
+}
+```
+  "correlation_id": "<guid>"
+}
+```
