SpoofSense is prepaid: you buy credits in the console, and each successful check decrements your balance.

​
Costs

New organizations start with free trial credits, so you can integrate before paying.

​
Rules

  • You’re only charged for scored checks. Input errors — invalid image, no face detected, image too large, bad threshold, backlit capture — return 4xx and cost nothing.
  • Every response tells you where you stand via credits_remaining.
  • Zero balance disables your keys. Calls return 402 INSUFFICIENT_CREDITS until you top up in the console. Creating a verification session also pre-checks the balance, so you’ll never hand your client a token that’s doomed to fail.
  • Verification session retries are free until a check actually runs: a 422 retake (blur, no face) doesn’t charge; the charge lands when the capture is scored.
Surface 402 INSUFFICIENT_CREDITS to your operations team, not your end user — it means the account needs a top-up, not that verification failed.
