Once you have your Userapi.ai Token, you can configure the gem with:

Open up the initializer file config/initializers/userapi.rb and add your API Key as the following:

  UserapiAi.configure do |config|
    config.access_token = ENV["USERAPI_USER_TOKEN"]
  end

Imagine is a Midjourney command that allows you to use AI to generate images. You can use it to generate images of people, animals, objects, and anything else you can imagine.

    client = UserapiAi::Client.new(service: :midjourney)
    result = client.imagine(prompt: "nice girl")
    # or
    result = client.imagine(prompt: "nice girl",
                            webhook_url: "https://example.com/imagine/webhook-url",
                            webhook_type: "progress", # or result
                            account_hash: "a7d44910-88a6-4673-acc8-d60ffc3479a6",
                            is_disable_prefilter: false)
    # then
    client.status(result)

    client = UserapiAi::Client.new(service: :midjourney)
    result = client.status(hash: "xxx-xxx")
    result = client.variation(hash: "xxx-xxx", choice: 1)
    result = client.upsample(hash: "xxx-xxx", choice: "v6_2x_subtle")

    result = client.upscale(hash: "xxx-xxx", 
                            choice: 1,
                            webhook_url:  "https://example.com/upscale/webhook-url",
                            webhook_type: "result")

      local_paths.each do |path|
           f = File.open(path)
           ...
        end
