guys, just FYI
this needs to be added to https://github.com/apify/actor-whitepaper?tab=readme-ov-file#environment-variables cc @jancurn
also https://docs.apify.com/platform/actors/development/programming-interface/environment-variables

@mhamas Looking at https://github.com/apify/actor-whitepaper?tab=readme-ov-file#environment-variables - maybe we should use ACTOR_MAX_TOTAL_CHARGE_USD for this?

[jancurn]

Yes, I called this ACTOR_MAX_TOTAL_CHARGE_USD because the function is called Actor.charge(), for consistency. Also, the word "cost" is used on platform in the context of platform costs, which is typically lower than what is charged, because devs have margin. From point of view of the developer, "costs" is their costs, not what they charge their users.

@novotnyj @mhamas thanks for this, just pls guys can you make the naming consistent also on the platform?

[mhamas]

Discussed with @novotnyj and we can rename this on platform as well. @novotnyj can you create a ticket for this into this sprint and do it with higher priority, co we can get it done before it actually starts to be properly used. Thx
