Why You Need This
How this feature boosts your daily productivity
Raw API responses are hard to read and easy to misinterpret. The Response Inspector turns dense payloads into a searchable, structured view with formatted JSON, headers in a clean table, and status plus timing details that are easy to scan. That means you can spot a missing field, malformed body, or slow endpoint in seconds instead of copying the payload into another tool just to understand it.
How It Works
Get started in 4 simple steps
Set Up Your Request
Choose the HTTP method, enter the URL, and configure headers, auth, and body in the tabbed interface.
Send & Inspect
Hit send and see the response instantly — formatted JSON, headers, status code, and latency metrics.
Save & Organize
Save requests in tabs for quick re-use. Each project maintains its own request workspace and URL history.
Share & Debug
Copy as cURL for sharing. Send response data to your AI agent for analysis or debugging assistance.
