# API Tester Skill

This skill helps test and validate REST API endpoints with comprehensive request/response analysis.

## Capabilities

- Send HTTP requests (GET, POST, PUT, DELETE, PATCH)
- Validate response status codes
- Check response headers and content types
- Parse and validate JSON responses
- Test authentication (Bearer tokens, API keys, Basic auth)
- Measure response times
- Generate test reports

## When to Use

Use this skill when the user asks to:
- Test an API endpoint
- Validate API responses
- Check API authentication
- Debug API issues
- Generate API test reports
- Measure API performance

## Example Usage

```python
import requests
import json

# Test GET request
response = requests.get(
    'https://api.example.com/users',
    headers={'Authorization': 'Bearer token123'}
)

# Validate response
assert response.status_code == 200
assert response.headers['Content-Type'] == 'application/json'

data = response.json()
assert 'users' in data
assert len(data['users']) > 0

# Test POST request
payload = {'name': 'John', 'email': 'john@example.com'}
response = requests.post(
    'https://api.example.com/users',
    json=payload,
    headers={'Content-Type': 'application/json'}
)

assert response.status_code == 201
```
