Frequently Asked Questions

User-Agent Data & API

  • Where is the API's data coming from?

    User-Agent detection by userstack is based on a proprietary database mapping of User-Agent strings with a complete set of devices, browsers and operating systems currently in use and on the market.

  • How often is User-Agent data refreshed?

    Our database of User-Agent strings is updated multiple times a week, ensuring accurate and up-to-date User-Agent detection even for the most recently released hardware and software.

  • How scalable is this service?

    The userstack API is powered by apilayer cloud infrastructure, a system some of the world's most popular real-time API services are running on, making it highly scalable and flexible at any step of the way.

Plans, Pricing & Payment

  • What is the difference between free and paid subscriptions?

    The userstack Free Plan is a way of getting familiar with the API, offering basic API functionality and a limitation of 10.000 monthly API lookups.

    As soon as you need a higher volume or advanced API features, you can choose from one of the premium subscriptions or contact us for a custom solution.

  • Which subscription plan fits my needs?

    The most decisive factor when it comes to your technical requirements is the number of monthly User-Agent strings need processing per month. Other factors include HTTPS encryption and access to the Bulk Lookups and Crawler Detection features.

    Signing up for the Free Plan is a great way of getting to know the API and implementing it without any commitments.

  • Which payment methods are supported?

    Payments can be made via credit card (Visa, MasterCard, Discover, Diner's Club, American Express) or PayPal. Enterprise and high-volume customers may request annual bank transfer payments to be enabled. You can change your payment method at any given time in the "Payment" section of your account dashboard.

  • Can I also pay yearly?

    Yes. If you choose annual billing, the total price of your subscription plan will be 20% lower than the total amount you would pay with a monthly payment frequency.

API Access & Features

  • What is an API Request?

    Pricing is based on the number of monthly API requests allowed. Each time the userstack API service is used to look up a User-Agent string, one API request is consumed. API errors are not counted towards your monthly quota.

  • What happens if I exceed my API Request volume?

    Users will be automatically notified via email and in their account dashboard as soon as at least 75%, 90%, and 100% of their monthly API quota has been reached. Since we are aware that data requirements may be very variable, your quota may be exceeded by a maximum of 20%.

  • What is the API's uptime?

    Our API's system status is closely monitored around the clock. Every effort is made to ensure the highest possible level of availability and consistency, and we are proud to have an average uptime rate of nearly 100% (99.9%), calculated based on the past 12 months.

    There is a public API status page available at the following URL: status.userstack.com.
