Request Cost and API Credits

Each request to the YouTube Transcript API consumes API Credits from your account balance.
  • Cost per request: 10 API Credits
  • Credits are deducted only for successful requests.
  • Your total available credits depend on your active plan.
You can use your credits across all HasData APIs. The same credit balance is shared platform-wide.
Unused credits do not roll over. Any remaining credits expire at the end of the current billing period.
