Billing and credits ​

Pixapi meters model usage with credits. A request may consume credits based on the selected model, output count, resolution, duration, quality, and provider cost.

Credit lifecycle ​

  1. Your app sends a request with a model id and parameters.
  2. Pixapi estimates whether the account has enough credits.
  3. The model provider is called.
  4. Credits are consumed after successful output, or according to the model-specific task policy.

Refunded credits ​

If a generation task fails after credits were consumed or reserved, Pixapi returns the affected credits to the account and marks the ledger row as Refunded. See Image generation failures for common failure causes and retry guidance.

Insufficient credits ​

If the account does not have enough credits, Pixapi returns:

json
{
  "error": {
    "code": "insufficient_credits",
    "message": "Not enough credits for this request."
  }
}

Your application should show Credits, Billing, or an upgrade action instead of retrying automatically.
