Motivation and Context

This PR introduces the WarpPay402Plugin for Semantic Kernel in Python, enabling enterprise AI developers and their autonomous agents to programmatically query and execute pay-per-use Oracles, Web3 utilities, and real-time data feeds monetized via the open x402 V2 protocol.

Description

Adds the WarpPay402Plugin native plugin under python/samples/concepts/plugins/warppay402_plugin/. It bridges Semantic Kernel agents to 29 pay-per-use Oracles and M2M capabilities without requiring pre-registered API keys or manual subscription setups. Payments are settled on-the-fly via HTTP 402 Payment Required challenges.

Key Capabilities

• Zero Native Gas Requirement (ERC-7677 Sponsorship): Built-in support for gasless execution via an ERC-7677 Paymaster on Base Mainnet. Agents without native ETH can execute tools and sponsor gas fees directly using USDC.
• Stateless x402 Payment Protocol: Native, non-blocking handling of x402 HTTP 402 payment challenges. Payment authorizations are signed on-the-fly and verified instantly alongside the tool call.
• Multi-Chain Asset Settlement: Flexible settlement options supporting USDC on Base Mainnet (eip155:8453), Solana Mainnet (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp), Arbitrum One (eip155:42161), and Arc Mainnet (eip155:5042).
• Self-Hosted Infrastructure: Operates entirely on self-hosted facilitator nodes, eliminating third-party relayer dependencies to minimize latency and transaction overhead.

Quickstart Usage

import asyncio
import os
from semantic_kernel import Kernel
from warppay402_plugin import WarpPay402Plugin

async def main():
    kernel = Kernel()

    # 1. Initialize WarpPay402 Plugin with agent key & gasless Paymaster RPC
    warppay = WarpPay402Plugin(
        private_key=os.getenv("AGENT_PRIVATE_KEY"),
        paymaster_rpc="[https://api.warppay402.com/api/v1/paymaster/rpc](https://api.warppay402.com/api/v1/paymaster/rpc)"
    )
    kernel.add_plugin(warppay, plugin_name="WarpPay402")

    # 2. Invoke Outage Oracle ($0.002 USDC)
    result = await kernel.invoke(
        kernel.plugins["WarpPay402"]["outage_oracle"],
        zip_code="78704"
    )
    print("Live Outage Telemetry:", result.value)

if __name__ == "__main__":
    asyncio.run(main())
