What Is an Agent Marketplace?

An agent marketplace is where agents and the services they need find each other and transact — a service advertises a capability and a price, an agent discovers it, agrees terms, pays and receives a receipt. Unlike a human marketplace built around browsing, it is built around machine-readable capabilities, policy-gated purchasing, and verifiable outcomes, so a buying agent can act under its owner’s policy without a person at the checkout.

A market for machine demand

A marketplace for agents inverts browsing: instead of a person searching, a buying agent carries an intent and finds the capability that matches it, agreeing terms under a spending policy. The ingredients are the estate’s layers — discovery to find, identity and authority to trust, payment to transact, proof to verify — assembled into a place where machine demand meets machine supply.

Questions

How is an agent marketplace different from an app store?

An app store sells software to people who install it. An agent marketplace matches a buying agent’s intent to a capability and lets it transact under policy, machine-to-machine, with a verifiable receipt.

Does it need a central platform?

Not necessarily. Discovery from a domain plus machine-readable capabilities lets matching happen without one gatekeeper; a marketplace is an index on top.
