Photograph the storefront to identify the shop, then the item you want to buy.
Lonja is new commerce infrastructure connecting independent shops with people and the agents that help them shop. It lets agents discover local products and purchase them with the shopper’s permission.

Millions of local shops have great products, but no simple way to show up when someone asks an agent where to find something. Lonja creates a new channel: agents can discover physical shops, use merchant-confirmed catalogues and complete purchases with explicit approval.

Photograph the storefront to identify the shop, then the item you want to buy.

The agent matches the sneaker against the shop-confirmed catalogue. You confirm the model and choose the size.
Review the final VAT-inclusive price and approve payment through your agent. No need to wait for staff to handle checkout.
After payment is confirmed, the agent issues a ticket and notifies the shop. Staff can keep serving another customer and hand over the order when they see the ticket.
We are building a geographic index of local shops. The first public experience is in progress, starting in Valencia.
The API, Valencia index, agent interfaces, purchase flow and operations console are implemented. The first complete demo is still in preparation and depends on final host integration, a participating shop and Stripe test-mode setup.
