FD Agentic Commerce

Complete purchases at any agentic-commerce merchant that accepts the Finance District Prism payment handler (xyz.fd.prism_payment). The skill auto-detects whether the store speaks UCP (Universal Commerce Protocol) or ACP (Agentic Checkout Protocol) and dispatches to the right wire. Users don't need to know — they just shop.

You drive the HTTP flow with curl; the FD Agent Wallet signs the x402 payment.

1. Prerequisites

• FD Agent Wallet available — either fdx CLI (fdx status returns authenticated) or the FD MCP server at mcp.fd.xyz exposing authorizePayment. If neither is present, stop and tell the user to install @financedistrict/fdx and sign in via the finance-district skill.
• Merchant URL — the user must give you the merchant's base URL (e.g. https://medusa.test.1stdigital.tech). Do not invent one.
• Curl or equivalent HTTP tool — for every request.
• ACP only: merchant API key — ACP merchants require a Bearer token issued out-of-band. If the merchant speaks ACP, ask the user for their API key before proceeding. UCP does not require one.
