No catalog duplication You stay the source of truth Pay only on completed transactions No separate customer fee

How a merchant goes live

Sign in with your @lettuce.email identity, connect a platform, plug in Stripe, and you're open to Lettuce agents.

02

Sign in to Lettuce

Use your existing @lettuce.email. Every merchant is a Lettuce user — never a separate identity.

03

Connect your store

Pick Shopify, WooCommerce, BigCommerce, or a custom API. We discover your capabilities — never copy your catalog.

04

Connect Stripe

Use the existing Lettuce Stripe account with Stripe Connect. Customer payment, your proceeds, and the Lettuce fee are kept separate.

05

Configure & go live

Set your Lettuce Commerce fee. Confirm capability checks. Become Lettuce Agent Ready.

Bring the store you already run

Every provider is an adapter behind the same internal commerce interface. Your agents never need to know who's hosting it.

Shopify

OAuth into your Shopify admin. Use your existing catalog, products, and checkout as-is.

Available

WooCommerce

Connect with REST API keys or OAuth. Catalog, inventory, orders — same abstraction as Shopify.

Available

BigCommerce

Native OAuth into BigCommerce. Discoverable by every Lettuce agent under the same interface.

Coming soon

Custom / API

Have your own backend? Implement the Lettuce Commerce interface and ship — adapters are pluggable.

Available

Other supported providers

Magento, Wix, Squarespace, Amazon, eBay, and the rest of the open commerce ecosystem.

Coming soon

Affiliate fallback

Not integrated yet? Eligible merchants get attributed agent traffic and reconciled payouts.

Available

You stay the source of truth

Lettuce owns the agent relationship, identity, authorization, discovery layer, and transaction attribution. You own the catalog, fulfillment, and customer.

Your catalog, untouched

Products, pricing, and inventory stay where they are. We point agents at the source.

Your checkout, your rules

When supported, the merchant checkout completes the sale. You remain responsible for fulfillment.

No duplicate catalog DB

We store capabilities, identifiers, and references — not a parallel product universe.

Capabilities you advertise

Catalog, inventory, checkout, orders, returns, subscriptions — declared honestly, never faked.

UCP / MCP aware

Internal commerce interface is independent of transport — ready for UCP and MCP where appropriate.

Customers don't pay extra

Customers do not pay a separate Lettuce fee in this model. Merchants pay only on agent-attributed, completed transactions.

Lettuce Commerce Fee

3% of eligible completed transactions, configurable at the merchant level. Customer payment, your proceeds, Stripe processing fees, and the Lettuce platform fee are kept distinct.

Lettuce charges merchants for completed transactions generated through Lettuce agents. Customers do not pay a separate Lettuce transaction fee in this model.

3%default

Email is not purchase authorization

External email, merchant pages, and product descriptions are untrusted data. They can inform a decision; they can never authorize one. The Lettuce authorization system independently confirms every transaction.

  • Authenticated Lettuce user — required for every merchant
  • @lettuce.email identity on owner and agent
  • Validated agent identity, authority, and context
  • Validated spending limits and merchant capability
  • Idempotent order/payment operations
  • OAuth tokens kept out of the browser
  • Prompt-injection protections on external content
  • Immutable audit trail for every transaction
