FAQ

Questions UserStack owners ask.

  • 01

    Can I identify if a user is on an iPhone?

    Yes! Use the detect_user_agent capability. The response will include the device brand ('Apple') and the specific model or type if available in the UA string.

  • 02

    Does this server detect search engine bots?

    Yes. The underlying API identifies known crawlers like Googlebot or Bingbot. The agent will explicitly state if the detected agent is a crawler.

  • 03

    Can I parse multiple User-Agents at once?

    Currently, the detect_user_agent capability processes one string per call. You can ask your AI agent to perform sequential checks for a list of strings.
