AI-native payment infrastructure for the x402 protocol

Claw402 is an autonomous payment integration layer that enables AI agents to execute cryptocurrency transactions through standardized Model Context Protocol (MCP) interfaces. Built on the x402 protocol, Claw402 bridges the gap between large language model-based agents and blockchain payment infrastructure, positioning AI agents as first-class economic actors in decentralized payment networks.

Claw402 operates as a protocol translation layer between AI agent runtime environments (OpenClaw, AutoGPT, LangChain) and the x402 payment protocol. The system exposes x402 transaction capabilities through MCP-compliant interfaces, enabling agents to execute payments using natural language instructions translated to protocol-level operations.

• MCP-Native Design - First-class integration with Model Context Protocol for seamless AI agent compatibility
• Non-Custodial Security - Hardware-backed key isolation with time-bounded, scope-limited signing
• Declarative Transactions - Natural language payment semantics instead of low-level cryptographic operations
• Fault-Tolerant Execution - Idempotent operations, state recovery, and automatic circuit breaking
• Protocol Specialization - Purpose-built for x402, not generic blockchain abstraction

npm install @claw402/mcp-provider

from openclaw import Agent
from claw402 import X402Provider

agent = Agent(
    name="payment_assistant",
    providers=[X402Provider(
        network="mainnet-beta",
        wallet_path="~/.config/solana/agent.json"
    )]
)

# Agent autonomously executes payments
agent.run("Pay the invoice from Acme Corp for $250 using USDC")

claw402 serve \
  --network mainnet-beta \
  --wallet ~/.config/solana/agent.json \
  --port 3402

Autonomous SaaS Payments - AI agents manage recurring software subscriptions by executing x402 payments when renewals are required

Invoice Settlement - Accounts payable agents process incoming invoices and settle payments autonomously within approved parameters

Micropayment Content Access - Research agents pay per-article fees to access paywalled content during information gathering

Dynamic Resource Allocation - DevOps agents provision cloud infrastructure by paying compute providers via cryptocurrency spot markets
