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    \"user-agent-parser\": {\n      \"url\": \"https://user-agent-parser.api.klymax402.com/mcp\"\n    }\n  }\n}\n```\n\n## Quickstart -- HTTP (x402)\n\n```bash\ncurl -X POST \"https://user-agent-parser.api.klymax402.com/api/parse\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"userAgent\":\"...\"}'\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| `utility_parse_user_agent` | POST | `/api/parse` | $0.003 | Parse a user agent string into structured data |\n\n### `utility_parse_user_agent`\n\nUse this when you need to parse a user agent string to identify the client's browser, OS, device type, and bot status. Returns fully structured data.\n\n**Parameters**\n\n| Name | Type | Required | Description |\n|---|---|---|---|\n| `userAgent` | string | yes | The user agent string to parse |\n\nExample response:\n\n```json\n{\"browser\":{\"name\":\"Chrome\",\"version\":\"120.0\"},\"os\":{\"name\":\"Windows\",\"version\":\"11\"},\"device\":{\"type\":\"desktop\",\"vendor\":null,\"model\":null},\"engine\":\"Blink\",\"isBot\":false,\"botName\":null}\n```\n\n**When to use**: analytics pipelines that need to classify traffic by device or browser, detecting bot traffic in access logs, or adapting content based on client capabilities.\n\n**Not for**: HTTP header analysis (use `utility_parse_http_headers`), web scraping (use `web_scrape_to_markdown`), SEO auditing (use `seo_audit_page`).\n\n## Example agent prompts\n\n- \"Parse a user agent string to identify the client's browser, OS, device type, and bot status\"\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",
