Billing & Credits
Fail-closed economics — credits only burn on issued Verify PASS.
Core principle
1 credit = 1 verified PASS kit issued.
- FAIL consumes $0 credits (no burn).
- PASS burns 1 credit only when Verify PASS succeeds and the kit is issued.
- PASS + Verify FAIL consumes $0 credits (no burn). If verification fails due to an AttestLayer system error, the credit is not burned and any reserved burn is automatically restored.
This is enforced in code and cannot be overridden.
Buyer-safe resubmit (reliability, not billing)
- Each FAIL includes 1 priority resubmit within 7 days.
- Additional FAIL resubmits may be rate-limited for reliability (never charged).
