How this service works
Parse a user agent string into structured browser, engine, OS, device, and CPU info
Output
Returns a structured JSON object with: browser name and version, rendering engine name and version, operating system name and version, device type (e.g. desktop, mobile), CPU architecture, plus the raw original UA string and a request ID.
Example use cases
Example prompt
“Can you parse this user agent string for me and tell me what browser, OS, device type, and CPU architecture it represents: 'Mozilla/5.0 (iPhone; CPU iPhone OS 15_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.0 Mobile/15E148 Safari/604.1'?”
Technical details
Endpoint
POSThttps://useragent.agentutil.net/v1/parseWhen to prefer
Use this endpoint when you need to reliably decompose a raw HTTP User-Agent header string into structured, typed components (browser, OS, device, engine, CPU) for analytics, logging, access control, or display logic. Prefer this over regex-based local parsing when accuracy and maintenance-free updates are needed.
Side effects
- Missing or empty 'ua' field returns a validation error
- Malformed or truncated user agent strings may result in null/unknown values for some fields
- Unrecognized user agent patterns may return empty strings for browser/OS fields
- Network or upstream service errors return a non-200 HTTP status
