Introduction

PacSpace Balance API is usage-based settlement infrastructure. It gives you a simple, reliable way to record financial changes between parties, compute running balances, and verify that both sides agree — all through a straightforward REST API.

No servers to manage. No reconciliation spreadsheets. No late-night debugging of ledger mismatches. Just three API calls to verified settlement.

Core Capabilities#

Capability	What It Does	API Call
Emit	Record a credit or debit delta between two parties	POST /api/v1/balance/delta
Query	Derive a running balance from all verified deltas	GET /api/v1/balance/derive/:customerId
Verify	Compare your balance against a counterparty's — find discrepancies instantly	POST /api/v1/balance/compare

How It Works#

1. You emit deltas — every time money moves, usage accrues, or a charge applies, you record it as a signed delta (positive or negative).
2. We derive balances — PacSpace maintains an immutable, ordered log of deltas and computes the current balance on demand.
3. Both sides verify — each counterparty can independently check that their view of the balance matches. Discrepancies surface immediately, not at month-end.

Every delta is cryptographically anchored, meaning it cannot be altered or deleted after the fact. You get a tamper-proof audit trail without building any of the underlying infrastructure yourself.

Why PacSpace#

• Zero infrastructure — no databases to configure, no event buses to wire up, no reconciliation jobs to schedule.
• Real-time verification — stop waiting until the end of the billing cycle to discover mismatches.
• Immutable record — every delta is permanently recorded and independently verifiable.
• Usage-based pricing — you pay for what you use. No seat licenses, no upfront commitments.
• Three calls to settlement — emit, query, verify. That's the entire integration surface.
