Integration | PacSpace — Integrate in Minutes

Quick start

A single API call records a delta and returns a verifiable proof.

import { PacSpace } from '@pacspace-io/sdk';

const pac = new PacSpace({ apiKey: process.env.PACSPACE_API_KEY });

// Record usage as it happens
const delta = await pac.balance.emit('cust_12345', -182, 'gpu_burst_capacity');
const { receiptId } = delta;

// Derive the verifiable balance at any time
const balance = await pac.balance.derive('cust_12345');

Real-time verification

Know the moment it's verified

When a delta is verified, we deliver a signed webhook to your endpoint. Your records update automatically. No polling. No guessing.
