Sonna.ai uses a simple, character-based credit system. You purchase characters in bulk and consume them as you use the API.

Pricing Plans

We offer flexible plans to suit your scale:
  • Pro: $12.50 for 1,250,000 Characters
  • Max: Custom pricing for high-volume users.

Monitoring Usage

You can monitor your remaining credits and usage history directly in the Developer Dashboard.
  • Current Balance: Shown at the top of the dashboard.
  • Usage History: A 7-day breakdown of character consumption.

Insufficient Credits

If your account balance reaches zero, API requests will fail with a 402 Payment Required error:

{
  "error": "Payment Required: Insufficient credits"
}
To resume service, simply top up your credits from the dashboard billing section.
