+# OpenAPI Tools with the Responses API
+
+This sample shows how to use OpenAPI tools with a `ChatClientAgent` using the Responses API directly.
+
+## What this sample demonstrates
+
+- Defining an OpenAPI specification inline
+- Creating an `OpenAPIFunctionDefinition` for the Frankfurter exchange rate API
+- Using `FoundryAITool.CreateOpenApiTool()` with `ChatClientAgent`
+- Server-side execution of OpenAPI tool calls
+
+## Prerequisites
+
+- .NET 10 SDK or later
+- Microsoft Foundry service endpoint and deployment configured
+- An authenticated Azure identity (for example, sign in with `az login`)
+
+Set the following environment variables:
+
+```powershell
+$env:FOUNDRY_PROJECT_ENDPOINT="https://your-foundry-service.services.ai.azure.com/api/projects/your-foundry-project"
+$env:FOUNDRY_MODEL="gpt-5.4-mini"
+```
+
+## Run the sample
+
+```powershell
+dotnet run
+```
+
