How this service works
User-Agent parser: browser + version, engine, OS, device type and bot detection in one deterministic call - traffic triage for agents
Output
Returns a structured breakdown of the User-Agent string including: browser name and version, rendering engine (e.g. WebKit, Blink, Gecko), operating system and version, device type (desktop, mobile, tablet), and a bot detection flag indicating whether the client appears to be an automated agent or crawler.
Example use cases
Bot traffic filtering for web app
“I'm getting suspicious traffic on my site. Can you check this user agent — 'python-requests/2.28.0' — and tell me if it's a bot, what tool it is, and what OS or device it's running on?”
Browser compatibility triage for support
“A user is reporting a bug and sent me their user agent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36'. Can you break it down — browser, version, engine, and OS — so I know what environment they're on?”
Device type detection for responsive design
“Before serving a page, I need to know if this user agent belongs to a mobile, tablet, or desktop device: 'Mozilla/5.0 (Linux; Android 13; Pixel 7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Mobile Safari/537.36'. Can you parse it and give me the device type?”
Technical details
Endpoint
GEThttps://money-reactor.makar52nn2016.workers.dev/api/ua-parse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, deterministic, single-call UA parsing without spinning up a full analytics stack. It is ideal for agents doing real-time traffic triage, bot filtering, or device-aware routing at the edge. Prefer it over regex-based solutions or heavyweight analytics libraries when you need structured output with bot detection included in one atomic call.
Side effects
- Missing or empty User-Agent string may return null/unknown fields
- Unusual or spoofed UA strings may produce incorrect classifications
- Very new browser versions not yet in the parser's database may fall back to partial results
- Rate limiting or payment failure (x402) returns 402 Payment Required
