API Client

The API Client is a built-in HTTP client aimed at your running app.

• Compose method, URL, headers, query string, and body in one panel.
• Fire the request and read status, headers, and body from the live response pane.
• Use it to smoke-test an endpoint while you watch the same call appear seconds later in Requests and Logs.

Handy when you want to trigger traffic deliberately for architecture or security analysis.

The API Client also exposes an OpenAPI spec panel. From there you can generate, download, and compare an OpenAPI 3.1 document enriched with real recorded traffic. See OpenAPI generation for the full CLI and drift-check workflow.
