💰 Pricing

Event	Price (USD)	When it is charged
Court opinion (apify-default-dataset-item)	$0.05	Charged per result row returned.

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.05 = $5.00 plus the start fee.
