REST API

Quickstart

If you want to check out the API we provide, try out the following code: 

$ curl https://api.kwelo.com/v1/network/user-agent/details/Mozilla%2F4.0%20%28compatible%3B%20MSIE%206.0%3B%20Windows%20NT%205.1%3B%20SV1%3B%20.NET%20CLR%201.1.4322%29
{"data":{"user_agent":"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)","details":{"os": {...}, "device": {...}, "client": {...}}}}

Our API provides an easy way to retrieve the user agent information of a given User-Agent header and use it in your programs.

Usage

Using our API is extremely simple. Make a HTTP GET request and fetch the results in JSON or JSONP format. For JSONP format, add ?callback="something" in the request URL.

Our commitments

  • You can use this API for free but there is a sensible rate-limiting in place, see below.
  • The service is deployed on highly available clusters of major cloud providers (AWS, GCP, etc.) which means it should always be up, no matter what.
  • This API is here to stay ! My own software depends on these services so I'll keep them running and improving for the years to come.
  • I'm a bit obsessed with quality and performance. If you see anything strange or slow, contact me.

Rate-limiting

The requests are throttled at 1 per second which should be plenty for most use cases. If you hit the speed limit the service will return a 429 http status code.

If you need more, you can get unlimited access for a small contribution by reaching out to me at hello@kwelo.com and we'll sort things out depending on your situation and use-case.
