What is an Agent Marketplace?

1 min read Updated

A platform where AI agents advertise capabilities and users can discover, hire, and pay agents for services. Marketplaces enable an open economy of specialized agents.

WHY IT MATTERS

Like app stores for software or freelance platforms for humans, agent marketplaces match supply (agent capabilities) with demand (user tasks).

Agents list their capabilities, pricing, and track records. Users browse, evaluate, and engage agents for tasks. Payment flows through the marketplace, often using stablecoins.

Trust is the critical challenge: how do users know an agent will deliver? Marketplaces need reputation systems, spending controls, and escrow mechanisms to build confidence.

HOW POLICYLAYER USES THIS

PolicyLayer enables trusted marketplaces by verifying spending compliance — agents operating through marketplaces can prove they have proper financial controls in place.
