AffixIO trust infrastructure

The problem

Autonomous systems can now buy, write, export, reserve and change state, but most products still treat them like ordinary browser traffic.

Where AffixIO sits

AffixIO verifies the actor, policy, user consent, action scope, eligibility and audit needs before the action runs.

Why it matters

The result is a signed allow or deny decision that product, risk, audit and support teams can understand.

Built for developers

Use the affixio SDK from npm to add proof checks to Node.js services without storing extra personal data.

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");
