@aimarket/agent

AI Market Protocol v2 consumer SDK for TypeScript — Electron, Node.js servers, and web apps.

Discover, pay for, and invoke AI capabilities from the decentralized marketplace, with production cryptography:

• Ed25519 (ed25519:<base64>) for canonical hub / invoke signatures
• EIP-712 (keccak256 + secp256k1, eip712:0x<r><s><v>) for on-chain channel debits

Part of the AIMarket SDKs (Dart · TypeScript · Rust) — all three ship the same version and the same model shapes, enforced by an ecosystem parity guard in CI.

Install

# Published on npm (v0.1.1+ — CommonJS require() on Node 20/22):
npm install @aimarket/agent

# ESM / TypeScript:
import { AimarketAgent } from '@aimarket/agent';

# CommonJS:
const { AimarketAgent } = require('@aimarket/agent');

Quick start

import { AimarketAgent } from '@aimarket/agent';

const agent = new AimarketAgent({
  hubUrl: 'https://modelmarket.dev',
  walletKey: loadYourWalletKey(),
});

// Discover capabilities for an intent — returns a ranked PlanStep[].
const plan = await agent.discover({
  intent: 'ATS scoring rules for fintech roles',
  budget: 1.0,
  limit: 5,
});

// Open a $5 channel (good for ~50 calls), then invoke the best match.
const channel = await agent.openChannel(5.0);
const result = await agent.invoke({
  capabilityId: plan[0].capability.capability_id,
  input: { target_role: 'Senior PM', industry: 'fintech' },
  channelId: channel.channel_id,
});

console.log('Output:', result.result, '· cost $', result.price_usd, '· TEE', result.tee_verified);
await agent.closeChannel(channel.channel_id);
