Record usage deltas. Derive verifiable balances. Compare both sides. Checkpoint at period-end. The Balance API turns billing disputes into math problems.
Record usage as a signed, immutable delta.
Compute the verifiable balance on demand.
Surface the exact point of divergence.
Lock period-end proof for invoicing.
Each billing window produces a single checkpoint — a tamper-evident fingerprint covering every verified delta in the period. Attach it to an invoice, embed it in a dashboard, or expose it through your API. Your counterparty can independently confirm the entire period without involving you or PacSpace.
One side integrates PacSpace. The other side never has to. Both get the same verifiable record.
