With Device Detection you can input a User Agent, a TAC value, or a native app key. For Geolocation, latitude and longitude will give you the location result.

Data files for our Big, Bigger, Biggest, and Bespoke solutions are produced Monday through Thursday. Data files for our free service are produced once a month. This schedule may be disrupted by UK bank holidays. When this does happen there will be prior warning in the form of a blog or email.

It's great that you want to remove the manual process of pulling the data file. Simply supply a License Key in your call to the Device Detection Pipeline or Engine builder and automatic updates for the Device Detection database will be enabled.

Usage sharing helps us maintain the accuracy of the data file via machine learning. We get data on all the devices, browsers, and operating systems you see in your ecosystem. When using the 51Degrees cloud service or on-premise pipeline, usage sharing is enabled by default. Usage sharing can only be disabled when using the on-premise pipeline.

Our Cloud Configurator contains all available properties. The properties you will need to pay for are shown with a dollar icon.

On rare occasions, we mark some of our properties as obsolete – this is dependent on their relevancy and popularity. Once a property has been marked as obsolete, it will remain in the data files but any new devices will contain default values for that property. If a property you frequently use has been marked as obsolete and is still required for your use case, please let us know and we may re-evaluate our decision.

To cover additional costs in the transaction process there is a $75 fee. Alternatively you can pay by credit card to avoid these fees.

American Express, VISA, and Mastercard are all supported.

There are a few reasons your User Agent might not be detecting correctly. It could be a brand new device or browser in development stage, or your data file could be out of date. If you have a User Agent that you'd like more information on, test it with our User Agent Tester. If there is no data on that particular User Agent, please email it to datasupport@51degrees.com and we'll investigate.

The SupportedBearers property values do not explicity give which generation of mobile networks the device supports, but rather it lists the radio technologies supported by the device for each generation of mobile networks. For example, 'LTE' (Long Term Evolution) for 4G and 'NR' (New Radio) for 5G.

We most likely haven't seen that exact User Agent string across all of our global deployments, therefore the algorithm is trying to make the closest match. Send us any data that has a difference higher than 15 and we'll investigate.

Since the release of iOS 12.2, Apple have made it increasingly harder to detect between Apple devices. It is generally not possible to identify Apple devices from the User Agent alone – JavaScript can be run to help determine the device model.

This depends on your target development language, but in .NET and Java you can switch easily between on-premise and cloud by calling the 'UseOnPremise' or 'UseCloud' Pipeline builder methods. For enterprise products, you must have a License for both on-premise and cloud.

You can refer to one of the many examples in our documentation.

A Pipeline is a customizable data processing system. At the most basic level, input data is supplied in the form of evidence. One or more flow elements in the Pipeline then perform processing based on that evidence and optionally, populate data values that are required by the user.

Yes! Please keep your Resource Key in a safe place, this is helpful for troubleshooting if you come across an issue.

For those on our cloud solution, you will automatically be using the latest data. To start collecting UA-CH data, you will need to regenerate your Resource Key with our Cloud Configurator to include the three Accept-CH Headers for hardware, platform, and browser.

Enabling UA-CH will be dependent on how your configuration is called, e.g., via the Pipeline API, server-side code, or client-side code. We've described these various scenarios together with examples within our documentation. You will need to be using version 4.4.0 or later of our service to enable User Agent Client Hints.

Yes. In fact, this is recommended. The device detection algorithm will use the UA-CH data where possible. However, if a match cannot be found for the supplied UA-CH values, then the User Agent will be used as a fallback. See the Getting Started examples for a demonstration of how to supply UA-CH evidence in parallel with User Agents

It’s difficult to provide a concrete answer due to Google’s tendency to change the timeline to suit their needs. We are working towards the timeline provided by Google, but this is subject to change. Please refer to their official timeline for the latest dates.

The User Agent tester parses the information from the submitted User Agent (UA) – there is no exchange between the browser and server. To obtain User Agent Client Hints (UA-CH) data, the information is exchanged between the browser and server – it's not part of the UA string. To identify the UA-CH that are sent with your UA string, we recommend you use our Me page.
