API-First Implementation

Python
import requests

# Scan agent code for security issues
response = requests.post(
    "https://agentshield-api-bartel-fe94823ceeea.herokuapp.com/api/v1/scan",
    json={
        "code": open("my_agent.py").read(),
        "bounty_code": "BETA5"  # Free scan
    }
)

result = response.json()
print(f"Risk Score: {result['risk_score']}/100")
print(f"Status: {result['status']}")

if result['status'] == 'SAFE':
    print(f"Certificate: {result['certification_id']}")
    print(f"Badge: {result['badge_url']}")
