Universal Commerce Protocol Protocol registry / en

Editorial identity

An independent observatory of the UCP standard.

A bilingual technical publication that verifies, structures and operationalizes primary sources on agentic commerce.

Mission

The UCP France Observatory documents the Universal Commerce Protocol for executive, product, data and engineering teams. Its role is to turn a moving specification into stable definitions, verifiable decisions, implementation procedures and control tools.

Independence and disambiguation

This is an independent publication. It is not the standard’s official website, a governance member or a spokesperson for Google, Shopify or any organization cited here. The official specification remains on ucp.dev. A citation or presence in the ecosystem matrix documents a sourced fact, never a partnership with this site.

What creates authority here

Scope

The main site keeps evergreen material: specification, architecture, implementation, governance and methods. Time-sensitive analysis is published on the separate outlet universalcommerceprotocol.blog.
