Pricing
$0.02 per transcribed minute = $20 per 1,000
| You are charged for | When | Price |
|---|---|---|
| Transcribed minute | Per minute of audio transcribed. | $0.02 |
| Actor Start | Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event). | $0.0000125 |
Pay-per-event pricing: you are billed per result, not per subscription — a run that returns nothing costs nothing beyond the start fee. Billing is handled by Apify on your own account. These are the live Apify store prices, in effect since 2026-08-08, and they are what you are actually charged.
