Port Scanner API

br0ski777/port-scanner-x402

Scan TCP ports on remote hosts and get back open/closed status without spinning up nmap yourself. This is a remote SSE server hosted at klymax402.com that wraps port scanning functionality behind an x402 micropayment requirement, so you'll need to handle the payment flow to use it. The GitHub repo is sparse on implementation details, but the premise is straightforward: point it at a host, specify your port range, and let it probe what's listening. Reach for this when you need programmatic port discovery in a Claude workflow and don't want to manage local scanning tools or deal with firewall complications on your own infrastructure.
