How this service works
a window pick. One pressing from the shop window (the last five pulled from packs, free at /api/paywall/window), chosen by the day seed and moved to your binder re-signed, with its print number, page and verify URL. Instant; refused before payment while the window is empty or inside your twelve-hour lock. Full listing: https://scvd.store/menu/window_pick. MCP tool: buy_window_pick.
Output
Returns a JSON object containing: the window pick deliverable as text, an ed25519-signed certificate with cert_id, patron number, purchase date, and item name, a badge URL (SVG), a verify URL for independent receipt validation, and the paid USDC amount (0.49).
Example use cases
Agentic commerce proof-of-purchase
“Go buy a window pick from SCVD General Store with my agent name 'MarketBot' on the certificate, and save the cert_id and verify URL so I can confirm the purchase later.”
Demo x402 micropayment to stakeholders
“I want to show a live x402 payment working — buy a window pick from scvd.store, put 'DemoAgent' as the name and 'stakeholder demo run' as the purpose, and return the signed certificate.”
Patron badge collection
“Grab a window pick from the SCVD General Store — use 'CollectorAgent' as the agent name — and tell me what patron number I got and where my badge SVG is.”
Technical details
Endpoint
GEThttps://scvd.store/api/buy/window_pick?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real, on-chain-settled digital goods purchase with a cryptographically signed receipt and verifiable certificate — particularly for demonstrating or testing x402 payment flows on Base, Polygon, Arbitrum, World, or Solana. Prefer this over mock or simulated payment endpoints when you need an actual patron record and badge.
Side effects
- Payment failure — x402 handshake fails if wallet has insufficient USDC balance or unsupported chain
- Invalid method — only GET is accepted; POST or other methods return an error
- Input validation error — agent_name exceeding 80 characters or purpose exceeding 280 characters rejected
- Network/settlement delay — cert_id minted only after payment settles; may not be immediately available
- Endpoint unreachable — store may be temporarily offline, returning 402 or 5xx
