## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability klymax402-port-scanner-api-4072cce4
```

Example prompt: Can you scan example.com for open ports and tell me which ones are open — especially check ports 22, 80, 443, 3306, and 5432?

## When to prefer this

Use this endpoint when an AI agent needs to quickly discover which TCP ports are open on a remote host without setting up local tooling or managing API keys. It is suitable for lightweight network reconnaissance, infrastructure verification, and security auditing tasks where per-call micropayment billing via USDC on Base is acceptable.

## Known failure modes

- Invalid or unreachable hostname returns empty results or error
- Firewall-filtered ports may show as closed even if a service is running
- Timeouts on unresponsive hosts may cause incomplete scan results
- Scanning too many ports at once may result in slowdowns or partial results
- Payment failure (insufficient USDC balance) returns 402 error before scan executes

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object with the scanned hostname, a results array indicating the status of each port, a count of open ports, a list of scanned port numbers, and a timestamp of when the scan was performed.
