II. How AI shopping works now

Two layers. An orchestrator decides where to look and compares. Your store agent knows what is real, and sells.

IV. Your store gets its own agent

Built from your catalog. It is a conversational storefront on your site, and it answers other agents when they ask.

  • Answers only from your catalogProducts, prices and stock from your live feed.
  • Never invents a price or a policyIf it is not in your catalog, it says so.
  • Other agents can ask it tooOver MCP and A2A, with the same answers.MuseMeta AIChatGPTGeminiClaude

Hi. I know the Excalibur Brothers catalog: products, prices, stock. Ask me for a gift or a budget.

V. One checkout. People and agents.

BMOS publishes checkout actions for people and for agents from the same offer. People go to secure.checkout.best, the default. Agents go to machine.checkout.best. The money goes to you.

X. Questions before you start

  

    
What does Read my store do?
Paste your store address and log in. BMOS then opens your public pages the way an agent does and lists every product it can find, with the problems that stop a sale. Nothing is installed and nothing is published.

    
Do agents really buy?
It depends on the agent. Muse shops for people inside Muse and pays with a one-time card from Link by Stripe. ChatGPT finds your products and sends the shopper to your checkout. Claude reads your feed and skill.md, then hands the shopper your checkout link.

    
How long does setup take?
Reading a store takes about a minute. Publishing is one click after that. Fixing red items is up to you.

    
Do I need to install anything?
Not to publish the feed. The cart, checkout and store agent widget is one optional script tag.

    
I have no GTINs. Is that a problem?
No. It never blocks publishing. Agents that match offers by barcode rank you lower until you add them.

    
Does it work with my platform?
Shopify, WooCommerce and plain HTML sites, with more checkout rails to come. We read what is public, the way a shopper would.

    
Who gets paid?
You. Card payments go to your own processor and crypto to your own wallets. You are the merchant of record.

    
What does it cost?
Free to start: one store and up to 100 products. Starter is $29 a month and Pro is $99 a month. There is no fee on sales on any plan.

    
Does BMOS take a cut of my sales?
No. There is no fee per sale on any plan.

    
Can I build a store if I do not have one?
Yes. Build your catalog in BMOS, let AI design the page, and publish. Agents can read your open feed from the first day, and checkout actions are already there.
