Why this is canonical

'The marketplace layer' is how platform architects and infrastructure investors describe the horizontal middleware that enables marketplace dynamics — payments, discovery, trust, and settlement — to be composed into new products. On .ai, it claims the organizing coordinate for that layer in the agentic era.

Where it fits

A few directions this coordinate opens —

Marketplace infrastructure platform
The foundational layer that enables any product or vertical to have marketplace dynamics — composable primitives for discovery, matching, payments, and governance.
Marketplace infrastructure companies and composable commerce platform builders
AI-native marketplace middleware
An AI-native middleware layer that sits between marketplace participants and provides intelligent mediation — recommendation, pricing, trust scoring, and settlement.
Platform economy infrastructure builders and AI marketplace enabling companies

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