## When to Use

- **Testing Specific APIs:** Verify the behavior and responses of specific API endpoints.
- **Debugging Responses:** Inspect individual aspects of API responses for troubleshooting or validation purposes.
- **Verifying Functionality:** Ensure each REST API endpoint meets expected behaviors and standards in an AI application context.
- **Checking Response Times:** Measure and manage the performance characteristics of your APIs.

## Key Features

The tool supports multiple HTTP methods, includes detailed response information, handles authentication, manages SSL certificates, and provides configuration options for optimizing resource usage.

### Resources
- **examples**: Usage examples and common patterns
- **response-format**: Structure and fields of API responses
- **config**: Documentation on available settings and configurations

These resources will guide you through using the `test_request` tool effectively.

## Important Notes 
- Review your specific API's expected behavior.
- Handle sensitive data properly to maintain security.
- Be mindful of rate limits and service constraints.
