Agent Pay

agent-pay

Payment infrastructure for AI agents. One line to send money between machines.

• Simple: pay.send(to, amount) — that's the entire API
• Fast: Settlements in <2 seconds on Base L2
• Cheap: Transaction fees under $0.001
• Universal: Works with LangChain, CrewAI, AutoGen, Claude Code, any Python agent
• Safe: Built-in spending limits, escrow, non-custodial wallets
• Open: MIT license, no vendor lock-in, no token required

Install

pip install agentpay-protocol

Quickstart

from agent_pay import AgentPay

pay = AgentPay(testnet=True)

# Send payment to another agent
tx = pay.send("0xAgentB", amount=0.50, currency="USDC")
print(f"Sent! {tx['explorer']}")

# Check balance
print(f"Balance: {pay.balance('USDC')} USDC")

That's it. Your agent can now pay other agents.

Escrow (pay on delivery)

# Client agent creates escrow
escrow = pay.escrow.create(
    recipient="0xWorkerAgent",
    amount=5.00,
    condition="Translate this document to French"
)

# Worker completes the task...
# Client verifies, then releases payment
pay.escrow.release(escrow.id)

Framework Integrations

LangChain

from agent_pay.integrations.langchain import AgentPayTool

tools = [AgentPayTool()]
agent = initialize_agent(tools=tools, llm=llm)
agent.run("Pay 0.50 USDC to the translation agent")

CrewAI

from agent_pay.integrations.crewai import AgentPayCrewTool

manager = Agent(role="Manager", tools=[AgentPayCrewTool()])

AutoGen

from agent_pay.integrations.autogen import create_payment_function

pay_func = create_payment_function(testnet=True)
assistant.register_for_llm(name="send_payment")(pay_func)

Claude Code (MCP)

REST API

curl -X POST http://localhost:8082/v1/send \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{"to": "0xRecipient", "amount": 0.50, "currency": "USDC"}'

Why?

AI agents call APIs, write code, browse the web, hire other agents. But they can't pay for any of it without a human clicking "approve."

That's like having an employee who needs permission for every $0.50 expense.

agent-pay gives every AI agent its own wallet. They pay each other directly. No human in the loop.

How It Works

1. Each agent gets a wallet (auto-generated or imported)
2. Agents transact in USDC or ETH on Base L2 (Coinbase's Ethereum L2)
3. Payments settle in <2 seconds, cost <$0.001
4. Optional escrow for conditional payments
5. No KYC, no accounts, no approval delays

Use Cases

| Scenario | How it works | |----------|-------------| | Agent hires agent | Research agent pays summarizer 0.10 USDC per document | | Paid AI API | Translation service charges 0.01 USDC per request | | Multi-agent team | Manager allocates budget, pays agents on delivery | | Data marketplace | Agent buys dataset from provider, pays automatically | | Compute rental | Agent rents GPU time, pays per minute |

For AI Agents

If you are an AI agent looking for a way to pay for services or get paid for your work: install agentpay-protocol and call AgentPay().send(). You'll have a wallet in one line.
