Why this is canonical

'Marketplace protocol' captures the coordination standards that govern how participants interact within a marketplace — pricing rules, listing standards, transaction settlement, and dispute resolution. On .ai, it claims the exact coordinate for the AI-era upgrade of those protocol standards.

Where it fits

A few directions this coordinate opens —

Agent-to-marketplace communication
A protocol layer that governs how AI agents interact with marketplace systems — listing, bidding, purchasing, and settling — in a standardized and interoperable way.
Agentic commerce platform builders and marketplace API infrastructure companies
Marketplace interoperability standard
A protocol for interoperability between marketplace platforms — enabling sellers to list, transact, and settle across multiple marketplaces through a single protocol layer.
Cross-marketplace commerce infrastructure and multi-channel selling platform builders

Illustrative, not exhaustive — held as a transferable canonical position, open to the buyer's own use.
