Complete a shopping checkout at any agentic-commerce merchant that accepts the Finance District Prism payment handler (xyz.fd.prism_payment). Works with both UCP (Universal Commerce Protocol) and ACP (Agentic Checkout Protocol) merchants — the skill auto-detects which protocol the store speaks. Use when the user asks to "buy", "order", "purchase", "shop", "checkout", or "get me something" from a storefront. Covers the full flow — merchant discovery, catalog/product browsing, checkout session create/update/complete, shipping-address collection, x402 payment authorization via the FD Agent Wallet MCP, and order confirmation. Single-merchant purchases only (no cross-merchant carts). Do NOT use for general crypto wallet operations or non-checkout wallet flows.
Manage agent crypto wallets and merchant payments via the Finance District platform (fdx CLI). Use when the user mentions wallets, tokens, crypto, DeFi, or merchant payments. Wallet operations — create/setup wallet, send/receive/transfer tokens, swap/trade/exchange crypto, check balance/portfolio, token prices, earn yield, stake, deposit/withdraw from DeFi vaults, x402 payments, pay for API services, fund wallet, bridge tokens, supported chains. Prism merchant operations — Points of Service (POS), create/list/manage API keys, settlement wallets, payment history, list payments, earnings, revenue, staff management (invite staff, revoke staff access, grant/revoke POS access for staff, list staff members). Trigger phrases include "set up wallet", "send ETH", "swap tokens", "check my balance", "show portfolio", "how much do I have", "earn yield", "buy/sell crypto", "use fdx", "create API key", "point of service", "payment history", "Prism", "invite staff", "revoke staff", "staff access", "manage staff", "list staff". Covers EVM chains (Ethereum, Base, Polygon, Arbitrum, Optimism), Solana, and Bitcoin. Do NOT use for general payment processing unrelated to Finance District or fdx.
