What Murf API usage costs

At the published pay-as-you-go rate, 100,000 characters costs about $3; one million characters costs about $30. The $2 minimum purchase matters mainly for very small test workloads.

API characters are not Studio VGT

Murf Studio subscriptions meter voice production with Voice Generation Time (VGT), while Murf API meters text characters. Do not subtract API character usage from Studio VGT or assume one converts into the other.

When to move beyond pay as you go

  • Your volume is high enough that a negotiated rate can materially change unit economics.
  • You need higher concurrency or request limits.
  • You need enterprise procurement, support or deployment requirements.

Budgeting tip

Track characters sent to the API before scaling. Regeneration, alternate pronunciations and A/B voice testing increase usage even when the final audio duration stays the same.
