About this tool
Everything you need to know about Voice Cloning API
The voice cloning API is a REST interface that creates clones and generates speech from them programmatically, so an application can do everything the product UI does without a person clicking through it. It's gated to Pro and above: 60 requests per minute on Pro, 120 on Max, and it bills the same way generation always does — about one point per second of speech, nothing extra for the API call itself. Cloning still costs no points; only generation does.

FAQ
Voice Cloning API — FAQ
Common questions users ask about the Voice Cloning API voice. If you need additional help, please contact us via the contact form or email us at support@vocallab.ai.
What plan do I need to get API access to voice cloning?
The API is gated to Pro and above, so a Free or Lite account can clone and generate in the product but can't call the API directly.
What are the actual rate limits?
60 requests per minute on the baseline tier that has API access, rising to 120 requests per minute on the Max plan.
Does creating a clone through the API cost points?
No, creating a clone is free of points through the API just as it is in the product — points are spent only when you generate audio.
How is a generation call billed?
The same way it's billed in the product, roughly one point per second of speech, calculated from the character count of the text sent.
