Protocol / standardPublic reference
ACP
Agentic Commerce Protocol
An open commerce standard connecting merchants with AI shopping surfaces through structured product information.
THE QUESTION IT ADDRESSES
How does an AI shopping surface understand a merchant’s catalog?
A concise reading of published information. The explanatory grouping below is editorial, not an implementation test.
A simplified mechanism
- A merchant supplies structured catalog data.
- The AI surface interprets products and inventory.
- The integration supports the relevant commerce experience.
What it does not establish
ACP is broader than transferring funds. The current OpenAI overview focuses on catalog ingestion and product discovery; verify checkout capabilities in current integration docs.
Where it fits
Commerce information and payment execution are different layers. A catalog integration alone does not supply a wallet or payment settlement.
