ApicAgent API

⭐ Beginner's Pick Development / No Auth Required Beginner HTTPS CORS
Free to Use Varies (check documentation)

Overview

ApicAgent parses User-Agent strings into structured device and browser information, returning details like browser name, version, OS, device type, and whether the client is a bot. The service is free with no API key required and supports CORS, making it suitable for client-side JavaScript calls. It is useful for lightweight analytics and conditional content rendering without a server-side library.

💡

Beginner Tip

No signup or API key is needed — just call https://api.apicagent.com/?ua=YOUR_ENCODED_UA with any URL-encoded User-Agent string. In a browser you can capture the current UA from navigator.userAgent and encode it with encodeURIComponent before passing it.

Common Errors & Troubleshooting

Missing or incomplete parsed fields Non-standard or custom User-Agent strings may not match known browser patterns.
Check if the browser_name and os_name fields are non-null before rendering; use a generic fallback label for unrecognized UAs.
URL encoding errors causing 400 Bad Request Passing a raw unencoded User-Agent string with spaces or special characters breaks the query string.
Always URL-encode the ua parameter value before appending it to the request URL.
CORS error in browser when using http:// Mixed content policy blocks HTTP requests from HTTPS pages.
Use the HTTPS endpoint https://api.apicagent.com/ instead of the HTTP version.
