CPA for IG besides CPI

Is there any goods CPA for instagram besides CPI, PPI. Something that not reqest users to istall app. I don`t like to lie people "Get free iphone 7 just using this steps: 1) click on link 2) verify that you human 3) install app"
I know that alot people works with Ogads but maybe where is other CPA that not so lying to users and propose something normal stuff?

Register on multiple CPA networks, shop around for the offers and see if you can adapt any to your audience.

I don`t know it is look like all offers are CPI. So maybe usual CPA without CPI doesn`t work thoese days for IG or twitter
