 ### Rental Actors
 
 Rental Actors are Actors for which you have to pay a recurring fee to the developer after your trial period ends. This empowers the developer to dedicate more time and effort to their Actors, thus ensuring they are of the _highest quality_ and receive _ongoing maintenance_.

 Most rental Actors have a _free trial_ period. The length of the trial is displayed on each Actor's page.

 After a trial period, a flat monthly _Actor rental_ fee is automatically subtracted from your prepaid platform usage in advance for the following month. Most of this fee goes directly to the developer and is paid on top of the platform usage generated by the Actor. You can read more about our motivation for releasing rental Actors in [this blog post](https://blog.apify.com/make-regular-passive-income-developing-web-automation-actors-b0392278d085/) from Apify's CEO Jan Čurn.

 ### Pay per event
 
-Pay per event Actor pricing model is very similar to the pay per result model. You still do not pay the underlying platform usage. Instead of results, you pay for specific events defined by the creator of the Actor. These events will vary between Actors, and will always be described, together with their pricing, on each Actor. Example events might be producing a single result, doing a unit piece of work (e.g. uploading a file) or starting an Actor.

+#### Do I need to pay for platform usage with pay per event Actors?

+In most cases, no — the majority of pay per event Actors include platform usage in the event price, so you only pay for the events. However, some Actors may charge platform usage separately, in addition to the event costs. Always check the pricing section on the Actor's page—it clearly states whether platform usage is included or not.
 
-When an Actor operates in [Standby mode](https://docs.apify.com/platform/actors/running/standby), you control how the background runs scale and how efficiently they are utilized. In this case, you are responsible for paying the platform usage costs of these runs in addition to the event charges. Some selected Standby Actors may have this usage component waived, so always check the pricing page of the specific Actor to determine whether you will be charged for usage or only for events.

 When you use a pay per usage Actor, you are only charged for the platform usage that the runs of this Actor generate. [Platform usage](./usage_and_resources.md) includes components such as compute units, operations on [storages](/platform/storage), and usage of [residential proxies](/platform/proxy/residential-proxy) or [SERPs](/platform/proxy/google-serp-proxy).
