AffixIO trust infrastructure

AffixIO vs Persona

Persona is established in identity or verification. AffixIO focuses on proof before autonomous action, agent permissions and privacy-preserving signed outcomes.

Privacy

AffixIO is designed around data minimisation and signed outcomes instead of collecting more information by default.

AI agents

AffixIO is positioned for AI agent identity, agentic payments, MCP tools and autonomous commerce.

Permissions

AffixIO checks whether an action is allowed in context, not only whether a person once passed onboarding.

Future readiness

Post-quantum attestation, SDK-first flows and machine-readable docs help developers build for automated traffic.

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");
