## API Integration Examples

### Using REST API

```python
import requests

# Authenticate
response = requests.post(
    'https://api.bdragentfactory.com/v1/auth/token',
    json={
        'client_id': 'your_client_id',
        'client_secret': 'your_client_secret',
        'grant_type': 'client_credentials'
    }
)
token = response.json()['access_token']

# Invoke text classification
response = requests.post(
    'https://api.bdragentfactory.com/v1/capabilities/cap_text_classification/invoke',
    headers={'Authorization': f'Bearer {token}'},
    json={
        'input': {
            'text': 'Customer reported water damage to basement'
        },
        'options': {
            'explain': True,
            'audit_trail': True
        }
    }
)

result = response.json()
print(f"Predicted Class: {result['result']['predicted_class']}")
print(f"Confidence: {result['result']['confidence']}")
```

### Using Python SDK

```python
from bdr_agent_factory import Client

# Initialize client
client = Client(api_key='your_api_key')

# Invoke capability
result = client.capabilities.invoke(
    capability_id='cap_text_classification',
    input={'text': 'Customer reported water damage to basement'},
    options={'explain': True, 'audit_trail': True}
)

print(f"Predicted Class: {result.predicted_class}")
print(f"Confidence: {result.confidence}")
```

## Common Use Cases

### Use Case 1: Automated Claims Triage

```python
from text_classification_example import TextClassificationCapability

classifier = TextClassificationCapability()

# Classify incoming claim
result = classifier.classify(
    text="Customer's vehicle was damaged in parking lot collision",
    explain=True
)

# Route to appropriate department
if result.predicted_class == 'auto_accident':
    route_to_department('auto_claims')
elif result.predicted_class == 'property_damage':
    route_to_department('property_claims')
```

### Use Case 2: Fraud Screening

```python
from fraud_detection_example import FraudDetectionCapability

fraud_detector = FraudDetectionCapability()

# Screen claim for fraud
result = fraud_detector.detect(
    claim_data=claim_data,
    explain=True
)

# Take action based on risk level
if result.risk_level in ['high', 'critical']:
    escalate_to_investigator(claim_data['claim_id'])
elif result.risk_level == 'medium':
    flag_for_manual_review(claim_data['claim_id'])
else:
    proceed_with_processing(claim_data['claim_id'])
```

### Use Case 3: Batch Processing

```python
from integration_example import ClaimsProcessingWorkflow

workflow = ClaimsProcessingWorkflow()

# Process multiple claims
claims = load_claims_from_database()
results = workflow.batch_process_claims(claims)

# Generate report
for result in results:
    print(f"{result.claim_id}: {result.final_decision}")
```

## Testing

### Running Unit Tests

```bash
# Run all tests
pytest test_examples.py -v

# Run specific test
pytest test_examples.py::TestTextClassification::test_basic_classification -v

# Run with coverage
pytest test_examples.py --cov=. --cov-report=html
```

### Example Test

```python
import pytest
from text_classification_example import TextClassificationCapability

def test_text_classification():
    classifier = TextClassificationCapability()
    
    result = classifier.classify(
        text="Water damage to basement after storm",
        explain=True
    )
    
    assert result.predicted_class == "property_damage"
    assert result.confidence > 0.7
    assert result.explanation is not None
    assert result.audit_id is not None
```

## Troubleshooting

### Common Issues

#### Issue: "transformers not installed"
**Solution**: Install transformers library
```bash
pip install transformers torch
```

#### Issue: "Model not found"
**Solution**: The examples use mock models by default. For production, specify model path:
```python
classifier = TextClassificationCapability(model_path='/path/to/model')
```

#### Issue: "Import error"
**Solution**: Make sure you're running from the examples directory:
```bash
cd examples
python text_classification_example.py
```

## Best Practices

1. **Always enable audit trails** for compliance
2. **Use explanations** for transparency
3. **Validate input data** before processing
4. **Handle errors gracefully** with try-except blocks
5. **Monitor performance** metrics
6. **Test thoroughly** before production deployment
7. **Keep models updated** for best accuracy
8. **Follow security guidelines** for API keys
9. **Implement rate limiting** for production use
10. **Review audit logs** regularly
