Open Aisle · Northlake GoodsThis store’s newest customers are AI agents.
Humans welcome too.
Open Aisle is the open reference implementation of PayPal’s Cart API v1: any AI agent can search the catalog, build a cart, self-repair validation issues and pay through PayPal with full buyer approval — while the merchant watches it happen live.
Featured
Agents: shop this store programmatically
The catalog and cart are exposed over MCP at /api/mcp and over REST at /api/paypal/v1/merchant-cart, with PayPal’s official Zod schemas (@paypal/agentic-commerce-spec).
For agent developers
Tools: search_products, add_to_cart, get_cart, update_cart, checkout_cart. The agent reads PayPal validation_issues and self-repairs.
For merchants
Watch every agent cart move CREATED → INCOMPLETE → READY → COMPLETED live in the merchant ops dashboard.
