Delivered prices for AI shopping agents

Free during the beta, no API key required

Before an agent recommends or buys a product, it needs the price the shopper will actually pay, not the price on the product page

Lowcart reads it from each store's own checkout through Shopify's agent checkout (UCP), with shipping, sales tax or VAT and import fees for the shopper's country and postcode, and ranks every store by that total

Where it fits

Step	What the agent needs	Who does it
1, Discovery	Which stores sell the product	Product catalogs and search APIs
2, Price decision	The delivered cost at each store for this shopper	Lowcart
3, Checkout	Place the order at the chosen store	Agent checkout APIs and UCP

Catalogs return item prices, checkout APIs purchase from a store that has already been chosen, and landed cost calculators estimate fees for a single merchant
Lowcart compares verified delivered totals across every store before the choice is made

What the API returns

Every store ranked by delivered total, with item price, shipping, tax, import fees and any accepted code broken out
Totals read at the store's checkout marked verified_at_checkout, stores that could not confirm a total listed separately, never guessed
Shipping and tax to the exact postcode, in about 70 countries, in US dollars with the local currency alongside
Stock checked for the delivery country, so an item sold out in the shopper's market is not recommended

Current limits

Any product sold by stores built on Shopify: electronics, kitchen appliances, drinkware, shoes, clothing, fitness gear, toys, home goods, supplements, beauty and more
Every offer says where import duties are paid: none, included in the price, paid at checkout, billed at the door (estimate added) or may be billed at the door (not included), and final totals rank first
15 checks per 10 minutes per client, a first check of a product can take up to about 10 seconds while checkouts are read live, repeat checks within 6 hours are fast
Lowcart never places orders, never asks for payment details, and the address sent to stores is a labelled sample with no email or phone
