How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
Returns structured data including the detected browser name and version, operating system name and version, device type (e.g. mobile, desktop, tablet), and a boolean or score indicating whether the user agent is likely a bot or automated crawler.
Example use cases
Bot traffic filtering in web logs
“I've got this user agent from a suspicious request: 'python-requests/2.28.1' — can you parse it and tell me if it's flagged as a bot, and what browser and OS it resolves to?”
Analytics device breakdown
“Parse this user agent string for me: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36' — I need to know the browser, OS, and device type for my analytics dashboard.”
Security audit of incoming requests
“We're seeing unusual traffic and I want to know if this user agent — 'Googlebot/2.1 (+http://www.google.com/bot.html)' — is actually a known bot, and what device and browser info is associated with it.”
Technical details
Endpoint
POSThttps://tanod.dev/v1/useragent?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, structured parsing of raw User-Agent header strings into browser, OS, and device components, especially when bot detection is also required. Ideal for enriching web analytics pipelines, filtering bot traffic, or making device-aware decisions in an agent workflow without maintaining your own UA parser.
Side effects
- Empty or missing user_agent field returns a validation error
- User-Agent string exceeding 1024 characters is rejected
- Highly obfuscated or malformed UA strings may produce low-confidence or unknown classifications
- Bot heuristic may produce false positives for uncommon legitimate browsers
