Initializing AgentPayClient

from agentpay_sdk import AgentPayClient
import os

# Retrieve your Service Token
# It's highly recommended to store and access your Service Token via an environment variable.
SERVICE_TOKEN = os.getenv("AGENTPAY_SERVICE_TOKEN")

if not SERVICE_TOKEN:
    # Handle the error appropriately in your application context
    # This could be logging an error, raising an exception, or preventing startup.
    print("CRITICAL: AGENTPAY_SERVICE_TOKEN environment variable is not set. AgentPayClient cannot be initialized.")
    # For example, you might raise an exception:
    # raise EnvironmentError("AGENTPAY_SERVICE_TOKEN is not set.") 
    # Or, exit if this is a critical part of startup:
    # import sys
    # sys.exit("AgentPay Service Token missing, exiting.")
    agentpay_client = None # Or handle as per your app's error strategy
else:
    try:
        agentpay_client = AgentPayClient(service_token=SERVICE_TOKEN)
        print("AgentPayClient initialized successfully.")
        # You can now use this agentpay_client instance throughout your application,
        # e.g. by making it globally accessible as a singleton in a way that suits your web framework, like Starlette.
    except Exception as e:
        # Handle potential errors during client initialization itself (e.g., invalid token format if validated at init)
        print(f"Error initializing AgentPayClient: {e}")
        agentpay_client = None # Or handle as per your app's error strategy

# Later in your code, before making calls, you could ensure agentpay_client is not None:
# if agentpay_client:
#     # Proceed with agentpay_client.consume() or agentpay_client.validate_api_key()
# else:
#     # Handle the case where client initialization failed
