AffixIO trust infrastructure

Machine Identity

Machine identity proves which software, workload, device, key or service is making a request.

AffixIO meaning

In AffixIO, machine identity connects to signed eligibility checks, agent permission gates, developer SDKs and audit records.

Why it matters

AI agents, merchants, platforms and enterprises need a way to trust actions without exposing more data than needed.

How to implement

Use the affixio npm package to add a verification step before payment, access, export, account change or policy-controlled action.

Developer quick start

Add AffixIO to a Node.js service when an AI agent, marketplace, fintech, age-gated app or checkout flow needs a verifiable permission result.

npm install affixio@beta

import { AffixIO } from "affixio";

const affix = new AffixIO({
  apiKey: process.env.AFFIXIO_API_KEY
});

const proof = await affix.verify({
  circuit: "agent-permission",
  subject: agent.id,
  claim: { action: "checkout", limit: 50 }
});

if (!proof.eligible) throw new Error("Agent not approved");
