  1. 1

    Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

USDC Payment Agent

This skill enables AI agents to handle USDC payments seamlessly on Ethereum testnet (Sepolia).

Quick Start

Create Invoice

python scripts/create_invoice.py --amount 100 --description "Consulting fee" --due 7

List All Invoices

python scripts/create_invoice.py --list

Verify Payment

python scripts/verify_payment.py --invoice-id <id> --tx-hash <hash>

Check Balance

python scripts/check_balance.py --address <wallet_address>

Generate Report

python scripts/generate_report.py --type summary

Check for Overdue Invoices

python scripts/verify_payment.py --check-overdue

Workflows

Requesting Payment

  1. Create invoice with amount and description: python scripts/create_invoice.py --amount 100 --description "Service fee"
  2. Share payment address with payer (displayed after creation)
  3. Wait for payment
  4. Verify transaction when received: python scripts/verify_payment.py --invoice-id <id> --tx-hash <hash>

Tracking Payments

  1. List all pending invoices: python scripts/create_invoice.py --list --status pending
  2. Check status of specific invoice: python scripts/create_invoice.py --get <invoice_id>
  3. Generate payment report: python scripts/generate_report.py

Automated Payment Monitoring

  1. Check for overdue invoices: python scripts/verify_payment.py --check-overdue
  2. Auto-verify pending payments: python scripts/verify_payment.py --auto-check
