@kakunin/verify

Certificate-enforcement middleware for services that receive traffic from Kakunin-certified AI agents. This package is a thin re-export of @kakunin/sdk/verify — published standalone so npm install @kakunin/verify works on its own.

npm install @kakunin/verify

// Next.js / Fetch, Express, Fastify, Cloudflare Workers, Hono, Remix
import { kakuninMiddleware } from '@kakunin/verify';

const enforce = kakuninMiddleware();
export async function middleware(req: Request) {
  const { agent, reject } = await enforce(req);
  if (!agent) return reject('Missing or invalid agent certificate');
}

Installing @kakunin/verify pulls in @kakunin/sdk; the two expose the same middleware, so use whichever import you prefer. Full docs at kakunin.ai/docs.
