Age Estimation is billed against Age Estimation finances — allocated to your account separately from your general funds.
  • Both the age-estimation fee and the document step-up fee draw on those finances. The step-up is charged as an Age Estimation Document Scan, so your general document scan credits are never used and it does not appear against your document scan usage.
  • Without available Age Estimation finances the feature is unavailable, no matter how much general balance the account holds — session creation is rejected.
  • The age-estimation fee is charged once per terminal result, on both COMPLETED and FAILED. Sessions that merely expire are not charged.
  • The Age Estimation Document Scan fee follows standard document verification billing: charged when the document check completes, and on failure only if your account is configured to charge all completed verifications.
  • Age Estimation finances can carry their own expiration, independent of your other funds.
At session creation your Age Estimation finances are pre-checked for both applicable fees; if they can’t cover the session the request is rejected — see error responses for how this surfaces on the API.
