The problem
Autonomous systems can now buy, write, export, reserve and change state, but most products still treat them like ordinary browser traffic.
AffixIO trust infrastructure
Age assurance without building a document warehouse.
AffixIO helps apps prove age eligibility with clear yes or no results for regulated access, commerce and online safety workflows.
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
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");Questions people ask
