## Description

This project is a request testing service and diagnostic utility designed to help developers inspect HTTP interactions and verify client-side network logic. It functions as a stateless server that echoes request metadata, including headers, parameters, and body content, back to the calling client to ensure data is transmitted as intended.

The service distinguishes itself by providing a platform for mocking REST API endpoints and simulating various server behaviors. Developers can use these endpoints to trigger specific HTTP status codes, test content negotiation, validate form data encoding, and introduce artificial network delays to observe how applications handle error conditions.

Beyond basic request inspection, the tool supports comprehensive integration testing by allowing users to verify authentication requirements and complex transmission patterns. It operates through a standardized interface that processes incoming traffic to provide predictable, repeatable responses for debugging and development workflows.
