# Set environment variables
os.environ["SKILL_BILLING_API_KEY"] = "your-api-key"
os.environ["SKILL_ID"] = "your-skill-id"

# Analyze patient symptoms
result = analyze_symptoms(
    symptoms="胸痛，呼吸困难，持续30分钟",
    age=65,
    gender="male",
    vital_signs={"bp": "160/95", "hr": 110, "temp": 37.2},
    user_id="user_123"
)

# Check result
if result["success"]:
    print("分诊等级:", result["triage"]["level"])
    print("紧急程度:", result["triage"]["urgency"])
    print("建议措施:", result["recommendations"])
else:
    print("错误:", result["error"])
    if "paymentUrl" in result:
