Character count

  • Supported letters, digits, punctuation, whitespace, and other characters count as one.

For example, Hello! uses six weighted characters.

How charges are applied

  1. Available free TTS characters are used first.
  2. Any remaining characters are charged to the account balance.
  3. The Console shows free usage, paid usage, and the final charge.

The 10,000-character registration grant is usage quota, not cash balance. It cannot be withdrawn or refunded.

Requests that fail before usable audio is generated are not billed.
