# Port Scanner API
[](https://port-scanner.api.klymax402.com/mcp)
[](https://x402.org)
[](LICENSE)
Scan TCP ports on any host -- check open/closed status, response time. 16 common ports by default. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
## Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
```json
{
"mcpServers": {
"port-scanner": {
"url": "https://port-scanner.api.klymax402.com/mcp"
}
}
}
```
## Quickstart -- HTTP (x402)
```bash
curl -X POST "https://port-scanner.api.klymax402.com/api/scan" \
-H "Content-Type: application/json" \
-d '{"host":"..."}'
# -> 402 Payment Required, with an x402 payment challenge in the response body
```
Any x402-aware client ([`@x402/fetch`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.
## Tools
| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
| `network_scan_ports` | POST | `/api/scan` | $0.008 | Scan common ports on a host to check which are open |
### `network_scan_ports`
Use this when you need to check which TCP ports are open on a host. Returns port status and response times in JSON.
**Parameters**
| Name | Type | Required | Description |
|---|---|---|---|
| `host` | string | yes | The hostname or IP address to scan |
| `ports` | array | no | Array of port numbers to scan (default: [21,22,25,53,80,110,143,443,993,995,3306,3389,5432,6379,8080,8443]) |
Example response:
```json
{"host":"example.com","ports":[{"port":80,"status":"open","responseTime":45},{"port":443,"status":"open","responseTime":52},{"port":22,"status":"closed","responseTime":null}],"openCount":2,"totalScanned":16,"scanDuration":1200}
```
**When to use**: server reconnaissance, verifying firewall rules, checking service availability, and infrastructure auditing.
**Not for**: DNS resolution (use `network_lookup_dns`), SSL certificate checks (use `security_check_ssl`), HTTP header analysis (use `network_analyze_headers`).
