A short snippet on how to make Ruby on Rails authenticate_or_request_with_http_basic respond with a JSON valid message upon failure.

class ApplicationController < ActionController::API
  include(
    ActionController::HttpAuthentication::Basic::ControllerMethods
  )

  before_action :http_authenticate!

  def http_authenticate!
    authenticate_or_request_with_http_basic do |key, secret|
      return if Resource.find_by(
        key: key,
        secret: secret
      )
    end

    render(
      json: 'Invalid credentials'.to_json,
      status: 401
    )
  end
end
