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.

01

OpenAI Agent + AffixIO

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

02

LangChain Agent + AffixIO

Add permission checks to chains and tools before high-risk execution.

03

CrewAI Agent + AffixIO

Give multi-agent workflows a shared proof step before external actions.

04

Stripe payment approval

Check delegated consent and spending scope before a payment provider receives the final intent.

05

Autonomous shopping agent

Verify product class, amount, merchant and user consent before purchase.

06

Ticket purchasing agent

Reduce scalping risk by checking buyer eligibility and purchase limits.

07

Browser automation agent

Gate form submission, account edits and checkout actions in browser agents.

08

Financial assistant

Add proof before account changes, transfers, exports and regulated recommendations.

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");
