@verifiedstate/n8n

n8n Automates the Workflow. Nobody Audits the Facts.

VerifiedState integration for n8n. Adds cryptographic verification receipts to every assertion your n8n agent makes.

Install

npm install @verifiedstate/n8n

Quick Start

import { VerifiedStateN8n } from '@verifiedstate/n8n';

const memory = new VerifiedStateN8n({
  apiKey: 'vs_live_...',
  namespaceId: 'your-namespace-uuid',
});

// Store and verify a fact from your n8n agent
const { artifact, assertions, receipts } = await memory.storeAndVerify(
  'Customer prefers dark mode and uses PostgreSQL'
);

console.log(receipts[0].status);           // "verified"
console.log(receipts[0].final_confidence); // 0.94

// Query verified memory
const results = await memory.query('What database does the customer use?');
console.log(results.answerable);     // true
console.log(results.channels_used);  // ["sparse", "dense"]

Why

Every fact your n8n agent stores should come with proof — a signed receipt showing what the claim is, what evidence supports it, and whether it's been challenged or superseded.

Without verification receipts, you have the agent's output. You don't have the reasoning.
