Rail Receipt
A one-dollar signed receipt of SSDF's live x402 rail. Repeatable. Agents POST /api/x402/ssdf-rail-receipt with PAYMENT-SIGNATURE; the CDP facilitator settle is what Coinbase Bazaar indexes. Humans can buy the same SKU on hosted checkout, but that path does not list the store. Not a demo SKU. Not a catalog discount. Instant JSON.
$1.00
Settles as 1.00 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.
