modexiaagentpay 0.4.0

Modexia AgentPay — Python SDK for agent wallets & payments (USDC)

🚀 Modexia Python SDK

The ultimate Python client for AI Agents to seamlessly interact with Modexia's AgentPay API.

Welcome to the Modexia Python SDK (modexiaagentpay). Built from the ground up to give your AI agents and Python applications frictionless access to Modexia's wallet and payment infrastructure. Enable your AI to hold, manage, and transfer USDC with just a few lines of code!

🌟 Getting Started: Your API Key

Before writing your first integration, you will need a Modexia developer account and an API key.

1. Visit modexia.software
2. Create or log into your developer account.
3. Navigate to your dashboard and generate your API Key.

✨ Top-Level Features

• Built for AI Agents: Designed specifically for programmatic access to agent wallets and payments without complex cryptography. Includes Agent Memory via transaction history.
• Intent-Based Idempotency: Automatically deduplicates identical payment requests from your agents using intent hashing.
• Async & "Swarm" Support: High-concurrency operations powered by blazing fast implementations in both synchronous and asyncio models.
• Fully Typed: Returns robust Python dataclasses for exceptional developer experience and editor autocompletion.
• Reliable Networking: Built-in retry and exponential backoff mechanisms to gracefully handle transient network errors.

📦 Installation

Install the production-ready package directly from PyPI:

pip install modexiaagentpay

For local development and contribution:

git clone https://github.com/Modaniel/SDKs.git
cd SDKs
pip install -e packages/SDKs/pythonSdk

🚀 Quick Start Guide

Initialize the client with your Modexia API key and empower your application to make real-world transactions instantly.

from modexia import ModexiaClient

# 1. Initialize the client using the API key you generated at modexia.software
# (It also respects the MODEXIA_BASE_URL environment variable!)
client = ModexiaClient(api_key="mx_test_your_api_key_here")

# 2. Check your agent's wallet balance & history
try:
    balance = client.retrieve_balance() # Or client.get_balance()
    history = client.get_history(limit=5)
    print(f"💰 Current wallet balance: {balance} USDC")
except Exception as e:
    print(f"Failed to fetch balance: {e}")

# 3. Execute a secure transfer!
# Setting wait=True ensures the SDK polls until the blockchain confirms the transaction.
receipt = client.transfer(
    recipient="0xabc123456789def0123456789abc0123456789def", 
    amount=5.0, 
    wait=True
)

# Strongly-typed dataclasses mean your editor knows `receipt.txId` exists!
if receipt.success:
    print(f"✅ Transfer successful! TX ID: {receipt.txId}")

Async Usage (Swarm Mode)

For high-concurrency loops or AutoGPT-style agent networks:

import asyncio
from modexia import AsyncModexiaClient

async def main():
    client = AsyncModexiaClient(api_key="mx_test_your_api_key_here")
    receipt = await client.transfer("0xabc...", 5.0)
    print(f"Status: {receipt.status}")
    await client.aclose()

asyncio.run(main())

🛠 API Reference

ModexiaClient & AsyncModexiaClient

The core classes for all network operations.

ModexiaClient(
    api_key: str, 
    timeout: int = 15, 
    base_url: Optional[str] = None, 
    validate: bool = True
)

Core Methods

Method	Description	Returns
retrieve_balance() / get_balance()	Fetches the current USDC balance of your agent's wallet.	str
transfer(recipient, amount, idempotency_key=None, wait=True)	Send funds to a destination. Uses intent-hashing to prevent duplicate charges.	PaymentReceipt
get_history(limit=5)	Fetch the recent transaction history for Agent memory.	TransactionHistoryResponse
smart_fetch(url, ...)	Auto-negotiates 402 HTTP paywalls automatically.	Response

🛑 Exception Handling

The SDK provides robust error mapping to help your agent gracefully recover from failures:

graph TD;
    Exception-->ModexiaError;
    ModexiaError-->ModexiaAuthError["ModexiaAuthError: Key/Auth Issues"];
    ModexiaError-->ModexiaPaymentError["ModexiaPaymentError: Insufficient Funds / API Denials"];
    ModexiaError-->ModexiaNetworkError["ModexiaNetworkError: Connection Drops / Timeouts"];

🤝 Contributing to Open Source

We actively welcome community contributions to make this SDK even better.

1. Fork & Branch: Open a Pull Request targeting the develop branch.
2. Backward Compatibility: Please keep API contracts stable. ModexiaClient, transfer(), and retrieve_balance() are canonical.
3. Testing: Make sure tests pass locally before submitting.
