@reinconsole/core

Canonical zod schemas and shared types for Rein — the control plane for AI agent payments. This package is the single source of truth for DB rows, API payloads, and SDK types across the whole stack.

Status: v0.1 — early open-source infrastructure, live on testnet. APIs may change before 1.0. See the stack running live: Rein console.

Install

npm install @reinconsole/core

What's in it

• The domain schemas — Agent, Policy, PaymentIntent, Decision, Receipt, GateReceipt, ReinEvent, and the id types (AgentId, OrgId, …) behind them. Everything that crosses a Rein boundary is one of these.
• Float-free money — decimal-string amount math; no 0.1 + 0.2 in anything that touches funds.
• Canonical forms — the exact byte layouts that intentHash and the decision hash chain commit to (canonical.ts). Pure and browser-safe by design: no node:crypto in this package.
• ERC-8004 ids — formatErc8004Id / parseErc8004Id for the canonical eip155:{chainId}:{registry}/{tokenId} agent identity format (lowercased, normalized, bigint-safe).
• Shared glob matcher — globMatch / globMatchAny, used by policy targeting and gate route pricing.

import { PaymentIntent, Decision, formatErc8004Id } from '@reinconsole/core';

const intent = PaymentIntent.parse(untrustedInput); // validated, typed
const id = formatErc8004Id({
  chainId: 84532,
  registry: '0x8004A818BFB912233c491871b3d84c89A494BD9e',
  tokenId: 7393n,
}); // "eip155:84532:0x8004a818…bd9e/7393"
