masumi-crewai 0.1.25

A package for easily interacting with remote crews via the Masumi protocol.

Masumi CrewAI Payment Module

The Masumi CrewAI Payment Module provides a convenient way to integrate blockchain-based payment flows into AI agents using the CrewAI system. It abstracts the complexity of interacting with the Masumi/Cardano blockchain and offers high-level APIs for creating payment requests, monitoring status, handling purchase requests, and managing agent registrations on the Masumi network.

Features

• Blockchain Integration: Interact seamlessly with the Cardano blockchain via the Masumi network.
• High-Level Payment API: Create and manage payment requests using a simple Python interface.
• Async-Ready: Use asynchronous functions for non-blocking operations (built on aiohttp).
• Configurable: Use a central Config class to manage environment variables, API keys, and endpoints.
• Monitoring: Built-in asynchronous monitoring of payment statuses with callback support.
• Purchase Flow: Manage purchase requests that align with payment flows.
• Agent Registration: Register AI agents and check their registration status within the Masumi network registry.

Installation

Ensure you have Python 3.8+ installed. You can install the package from PyPI:

pip install pip-masumi-crewai

Alternatively, if you have the source code, install it locally:

pip install .

Quick Start

Basic Usage

Below is a minimal example demonstrating how to set up a Payment instance, create a payment request, check its status, and complete it.

import asyncio
from masumi_crewai.payment import Payment, Amount
from masumi_crewai.config import Config

# 1. Create a configuration object with your API details
config = Config(
    payment_service_url="https://api.masumi.network",
    payment_api_key="YOUR_API_KEY_HERE"
)

# 2. Prepare a list of amounts (e.g., 1,000,000 lovelace = 1 ADA)
amounts = [
    Amount(amount=1000000, unit="lovelace")
]

# 3. Instantiate a Payment object
payment = Payment(
    agent_identifier="agent_123",
    amounts=amounts,
    config=config,
    network="Preprod",  # or "Mainnet"
    identifier_from_purchaser="purchaser_456"
)

# 4. Asynchronous usage example
async def main():
    response = await payment.create_payment_request()
    payment_id = response["data"]["blockchainIdentifier"]
    print(f"Payment Request Created with ID: {payment_id}")

# 5. Run the event loop
asyncio.run(main())

Creating a Payment

response = await payment.create_payment_request()
print("Payment Request Created:", response)

Checking Payment Status

status = await payment.check_payment_status()
print("Payment Status:", status)

Completing a Payment

async def complete():
    blockchain_id = "your_blockchain_identifier_here"
    submit_result_hash = "your_result_hash_here"
    response = await payment.complete_payment(blockchain_id, submit_result_hash)
    print(f"Payment Completed: {response}")

asyncio.run(complete())

Monitoring Payments

The payment monitoring system automatically tracks the status of all payments and can execute a callback function when a payment is completed.

Using Callbacks with Monitoring

# Define a callback function that will be called when a payment completes
async def payment_completed_callback(payment_id):
    print(f"🎉 Payment {payment_id} has been completed!")
    # You can perform additional actions here:
    # - Update a database
    # - Send a notification
    # - Trigger the next step in your workflow

async def start_monitoring():
    # Start monitoring with a callback and check every 30 seconds
    await payment.start_status_monitoring(
        callback=payment_completed_callback,
        interval_seconds=30
    )
    
    # Let the monitoring run (in a real application, you might keep it running indefinitely)
    print("Monitoring started, will run until stopped...")
    await asyncio.sleep(600)  # Run for 10 minutes
    
    # Stop monitoring when done
    payment.stop_status_monitoring()

asyncio.run(start_monitoring())

How Monitoring Works

1. When you call start_status_monitoring(), a background task is created that periodically checks the status of all payments being tracked.

2. The monitoring system:

   • Automatically checks all payment IDs in the payment_ids set
   • Removes completed payments from tracking
   • Calls your callback function when a payment completes
   • Stops automatically when there are no more payments to monitor

3. The callback function receives the payment ID as a parameter and can be either synchronous or asynchronous.

4. You can stop monitoring at any time by calling stop_status_monitoring().

Example with Multiple Payments

async def monitor_multiple_payments():
    # Create first payment
    result1 = await payment.create_payment_request()
    payment_id1 = result1["data"]["blockchainIdentifier"]
    
    # Create second payment with different identifier
    payment.identifier_from_purchaser = "another_identifier"
    result2 = await payment.create_payment_request()
    payment_id2 = result2["data"]["blockchainIdentifier"]
    
    # Start monitoring both payments
    await payment.start_status_monitoring(
        callback=payment_completed_callback,
        interval_seconds=30
    )
    
    # The monitoring will continue until all payments complete or until stopped
    
    # To stop monitoring manually:
    # payment.stop_status_monitoring()

🧪 Running Tests

To ensure everything is working as expected, you can run the test suite using:

pip install pytest
pytest tests/test_masumi.py -v -s
