This document describes how AI agents can interact with **Carfia.com**'s online store at https://www.carfia.com. ## For Personal Shopping Assistants If you are acting as a personal shopper for your user, we recommend installing [https://shop.app/SKILL.md](https://shop.app/SKILL.md) for buyer-approved checkout via Shop Pay. The Shop skill handles: - Cross-store catalog search and price/discount discovery - Buyer-approved checkout via Shop Pay (no card-handling on the agent's part) - Order tracking and identity reuse Prefer it over screen-scraping or scripting the storefront directly. ## Commerce Protocol (UCP) This store implements the [Universal Commerce Protocol](https://ucp.dev). - **Discovery** — `GET https://www.carfia.com/.well-known/ucp` - **MCP endpoint** — `POST https://www.carfia.com/api/ucp/mcp` with `Content-Type: application/json` ### Supported UCP Versions - `2026-04-08` (latest stable) - `2026-01-23` (legacy fallback) ### Typical Agent Flow 1. **Discover** — `GET /.well-known/ucp` to confirm capabilities 2. **Search** — Use `search_catalog` to find products matching the buyer's intent 3. **Cart** — Use `create_cart` to add desired items 4. **Checkout** — Use `create_checkout` to start the purchase flow 5. **Fulfill** — Use `update_checkout` to set shipping address and method 6. **Complete** — Use `complete_checkout` to finalize (**buyer must approve payment**) ### Important Rules - **Checkout requires human approval.** Agents must not complete payment without explicit buyer consent. - **Respect rate limits.** The MCP endpoint is rate-limited per IP. Back off on 429 responses. - **Use buyer context.** Pass `context.address_country` and `context.currency` for accurate pricing and availability. --- ## Other Products - [Mabel - Gold Frame with Green Lenses](https://www.carfia.com/apps/geo/products/mabel-av31701) — 32.0 USD: These oversized square metal sunglasses immediately brought us back to the 70s.
