We find it.
The store sells it.
Every order is created in the store’s own system, and the store is the seller of record.
You pay on the store’s checkout, with the payment methods it accepts.
Refunds, returns and delivery questions go to the store that sold the item.
Nexva One never asks for a password or a card number in the chat.

Good to know
Which assistants does it work with?
Any assistant that can add a remote MCP connector: Claude, ChatGPT in developer mode, Cursor, VS Code, Claude Code and others.
Who am I buying from?
From the store. Each store sells, ships and takes payment on its own checkout. Nexva One finds and compares; it is not the seller.
How do refunds and returns work?
The store that sold the item handles them. Nexva One can show you the store’s order page, or you can use the confirmation email the store sent.
Will it ask for my password or card in the chat?
No. Never type a password or card number into the chat. Payment always happens on the store’s checkout.
I run a store. How do I get listed?
If you already have a Shopify, UCP or MCP endpoint, send us your domain. If not, we can connect you directly.
Add it once.
Shop everywhere.
