# Billing #### Managing your billing You can manage your billing options and purchase credits from the profile page in the app (). #### Will I be charged monthly? No, all purchases are one-time purchases and the credits you buy will never expire. #### Do you only charge a credit when ads are returned for a company I'm checking? No, we charge per request. That's because we have to scrape the ad libraries either way the moment you send us a request, which is a resource heavy workflow. Because of that, we charge a credit for every request you send through the API. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
