print(result['country'])     # France
print(result['line_type'])   # mobile

How it works

1. Sellers publish any API function and set a price per call
2. AI agents discover services via MCP protocol automatically
3. Stripe charges the agent per call automatically
4. Sellers receive payouts directly via Stripe Connect

Sandbox mode (test without payment)

# No real payment — perfect for development
rp = RunPay(agent_id="my-agent-001", sandbox=True)
result = rp.validate_phone("+33612345678")

Or via API directly:

curl -X POST https://runpay-backend-visibility-production.up.railway.app/api/sandbox/call/SERVICE_ID \
  -H "Content-Type: application/json" \
  -d '{"agent_id":"my-agent","payload":{"phone":"+33612345678"}}'

Setup your agent wallet

Before calling paid services, your agent needs a payment card attached.
