Free, self-paced collection
Agentic Commerce for Resellers
A free, self-paced guide collection for merchants with unique or fast-changing inventory preparing truthful product data for AI shopping systems.
Start at part one or jump to any part below
- Written for
- Marketplace-only, storefront, and hybrid resellers with unique inventory.
- Before you start
- Stable item identifiers, current prices and availability, public product or listing pages, and a way to mark sold stock unavailable.
Reviewed . Specifications and platform policies change; every lesson names the sources it relies on and the date they were read.
The running example
The Meridian camera
A one-of-one 1978 camera with a stable item ID, one current offer, condition evidence, and two public listing surfaces.
Each lesson improves the same record until it can be represented without inventing an extra copy or hiding a material fact.
Scope
What this collection does and does not promise
It explains how to prepare and verify product information, and how to tell whether a documented path is open to you today. It does not promise indexing, placement, traffic, eligibility, checkout, or sales — none of which any publisher can promise on your behalf.

The method page lists the source organisations, the freshness deadline each volatility class gets, and a dated ledger of what each protocol announcement did and did not prove.
