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    \"password-strength\": {\n      \"url\": \"https://password-strength.api.klymax402.com/mcp\"\n    }\n  }\n}\n```\n\n## Quickstart -- HTTP (x402)\n\n```bash\ncurl -X POST \"https://password-strength.api.klymax402.com/api/check\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"password\":\"...\"}'\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| `security_check_password` | POST | `/api/check` | $0.003 | Check password strength with entropy and crack time |\n\n### `security_check_password`\n\nUse this when you need to evaluate password strength or security. Returns a score 0-100, strength rating (weak/fair/strong/excellent), estimated crack time, entropy bits, and improvement suggestions. Checks against top 1000 common passwords. Do NOT use for hash generation — use crypto_generate_hash. Do NOT use for input validation — use data_validate_json.\n\n**Parameters**\n\n| Name | Type | Required | Description |\n|---|---|---|---|\n| `password` | string | yes | The password to analyze |\n\n## Example agent prompts\n\n- \"Evaluate password strength or security\"\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\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",
