Quick start — crew with a payment-capable agent

from crewai import Agent, Crew, Task
from crewai_pqsafe import PQSafePaymentTool

payment_tool = PQSafePaymentTool()

finance_agent = Agent(
    role="Finance Agent",
    goal="Process approved supplier payments",
    backstory="You pay invoices that have been pre-authorized via PQSafe envelopes.",
    tools=[payment_tool],
)

pay_invoice = Task(
    description=(
        "Renew Perplexity Pro subscription at perplexity.ai — $20 USD. "
        "Use envelope: {envelope_json}"
    ),
    agent=finance_agent,
    expected_output="Payment confirmation with txId and rail",
)

crew = Crew(agents=[finance_agent], tasks=[pay_invoice])
result = crew.kickoff(inputs={"envelope_json": "<your signed envelope JSON>"})
print(result)

How it works

1. A human wallet owner issues a signed SpendEnvelope — a post-quantum (ML-DSA-65) token constraining agent ID, max amount, allowed recipients, and validity window.
2. The CrewAI agent calls pqsafe_pay with the envelope, recipient, amount, and memo.
3. PQSafe verifies constraints server-side and routes the payment over the cheapest available rail (Airwallex, Wise, Stripe, USDC/Base, or x402).
4. The tool returns {txId, status, rail}.
