One line. That's the integration.

import { withPulse } from '@kyvernlabs/pulse'
import { withX402 } from '@x402/next'

// Every payment → your dashboard. Blockchain-verified.
export const GET = withPulse(
  withX402(handler, config, server),
  { apiKey: 'kv_live_your_key_here' }
)

Features

Built for x402. Not retrofitted.

Wallet-Native Auth

SIWE (Sign-In With Ethereum) — no emails, no passwords. Your wallet is your identity. Cryptographically verified.

Auto API Keys

Connect wallet → get your kv_live_ API key instantly. SHA-256 hashed, shown once. Like Stripe's sk_live_ pattern.

Revenue Dashboard

Real-time revenue, calls, latency, error rates per endpoint. Your data only — multi-tenant isolation.

Customer Analytics

See which agent wallets pay you the most, which endpoints they use, first/last seen. On-chain verified.

On-Chain Verification

Every payment tracked with blockchain tx hash. Click through to BaseScan. Not analytics — proof.

One-Line Middleware

npm install @kyvernlabs/pulse → wrap your handler with withPulse(). Non-blocking, fire-and-forget.

Live proof

Real payments. Real blockchain.
Not a simulation.
