Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.\n\nPart of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.\n\n## Quickstart -- MCP\n\nAdd to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):\n\n```json\n{\n  \"mcpServers\": {\n    \"port-scanner\": {\n      \"url\": \"https://port-scanner.api.klymax402.com/mcp\"\n    }\n  }\n}\n```\n\n## Quickstart -- HTTP (x402)\n\n```bash\ncurl -X POST \"https://port-scanner.api.klymax402.com/api/scan\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"host\":\"...\"}'\n# -> 402 Payment Required, with an x402 payment challenge in the response body\n```\n\nAny 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.\n\n## Tools\n\n| Tool | Method | Path | Price | Description |\n|---|---|---|---|---|\n| `network_scan_ports` | POST | `/api/scan` | $0.008 | Scan common ports on a host to check which are open |\n\n### `network_scan_ports`\n\nUse this when you need to check which TCP ports are open on a host. Returns port status and response times in JSON.\n\n**Parameters**\n\n| Name | Type | Required | Description |\n|---|---|---|---|\n| `host` | string | yes | The hostname or IP address to scan |\n| `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]) |\n\nExample response:\n\n```json\n{\"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}\n```\n\n**When to use**: server reconnaissance, verifying firewall rules, checking service availability, and infrastructure auditing.\n\n**Not for**: DNS resolution (use `network_lookup_dns`), SSL certificate checks (use `security_check_ssl`), HTTP header analysis (use `network_analyze_headers`).\n\n## Example agent prompts\n\n- \"Check which TCP ports are open on a host\"\n\n## Payment\n\n- Protocol: [x402](https://x402.org) -- HTTP-native pay-per-call, no signup, no API key\n- Network: Base L2 (`eip155:8453`)\n- Asset: USDC\n- Facilitator: Coinbase CDP (primary), PayAI (fallback)\n- Also reachable via [ATXP](https://atxp.ai) (OAuth-wrapped x402, RFC 9728 protected-resource metadata)\n\n## Part of klymax402\n\n100 x402 micropayment APIs for AI agents -- one wallet, USDC on Base, zero signup.\n\n- Catalog: https://klymax402.com/llms.txt\n- Full API reference: https://klymax402.com/llms-full.txt\n- Live stats: https://klymax402.com/stats\n\n## License\n\nMIT\n",
