AffixIO trust infrastructure

Build agent verification examples that developers can copy.

Use these patterns to add AffixIO proof checks to the places where autonomous software becomes risky: payments, tickets, browser actions, finance, exports and paid tools.

Verify tool calls before an OpenAI style agent writes data, exports records or triggers checkout.

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");
