x402 Merchant Boilerplate
Copy-paste TypeScript for a first-party x402 resource: UUID v4 X-Idempotency-Key, X-Checkout-Id poll, X-BUYER-STATE, optional NET-7, and the Coinbase Business live-wire notes (ES256, AuthCaptureEvmScheme, 24h x402_url). Instant markdown. Not a hosted facilitator and not Coinbase Commerce.
$49.00
Settles as 49.00 USDC on Base. Coinbase Business takes its payment fee. SSDF INC receives the net.
- License or file delivered the moment settlement completes.
- Irreversible once paid. No card chargebacks. Refunds go through the Coinbase Business refund endpoint.
Electronically delivered. Not Florida sales-taxable (Rule 12A-1.032, F.A.C.). Delegated use books a 12% SSDF royalty on first pulse.
