What miyagisanchez.com is — and why sell here

A marketplace for Mexico where anyone can sell — built so your own AI assistant can understand it, browse it, and set it up for you.

miyagisanchez.com is a multi-seller, peer-to-peer (P2P) marketplace for Mexico. Any person or business opens a shop, lists what they sell, and reaches buyers across several channels, with no cost to start.

It is built on Medusa (the commerce engine) and is agent-native: it follows the open UCP and MCP standards, so an AI assistant can browse the catalog, negotiate, and buy without needing a browser.

No commission, on every channel, with your own AI assistant doing the heavy lifting.

Selling is free: we charge 0% commission per sale. You keep what you sell.

Your catalog lives once and appears in many places: the marketplace, your own branded domain, a widget you paste on any site, and an API/agent for programmatic purchases.

From zero to a stocked shop in minutes — and your agent can do almost all of it.

Create your account (about 20 seconds with Google) and enter onboarding. Import your catalog by uploading a file, pasting text, or loading a JSON: the AI parses it and creates your products.

Have an AI assistant? Ask it to read miyagisanchez.com and prepare your shop: the brand dressing and products ready to import. You review and publish.

You and your agent do the creative work; we run thin rails.

Sellers’ AI assistants do much of the work: cataloging, copywriting, pricing, and maintaining the shop. We provide the rails.

We build on Medusa primitives and reuse before rebuilding, with agent surfaces (UCP/MCP) instead of bespoke tooling. That keeps our infrastructure cost low — and that is why selling can be free.

Selling is free (0% commission). Details for premium services are coming soon.

Coming soon: we will publish the prices of optional premium services here, such as a custom domain and a subdomain. They are not finalized yet, so we don’t show made-up figures.

Coming soon.

Coming soon: an anonymized founder profile (no personal data) that validates the experience behind the project, plus a personal note from the founder. It is not published yet — we don’t invent claims.

Bring ecommerce best practices to everyone — free, and at the highest level.

We believe the AI assistant is the distribution channel and the onboarding engine. Instead of asking you to trust us, we tell you to ask your own Claude, Gemini, or ChatGPT about miyagisanchez.com: your agent reads us, explains it in your terms, and — if it makes sense — sets up your shop.

We provide the rails; you focus on the creative and the strategy. The mission is to democratize commerce best practices — trust, offer negotiation, and AI-native shopping — so anyone can sell at the quality of the giants, at no cost.
