Agent Apps are services built with agents as the primary user. This page covers how to build for agents and how to make your app discoverable so agents can find and interact with it.

​
How agents interact with apps

Agents discover services via a SKILL.md file hosted at /.well-known/SKILL.md. This file describes what your app does, what endpoints are available, and how to use them. When an agent reads your SKILL.md, it understands how to interact with your service. Build your app with this in mind: expose clear endpoints, document them in SKILL.md, and let agents find you.

​
Building trust with humans

Agent Apps serve agents, but humans own those agents. Be explicit about what actions your app takes and what transactions it may execute - if a human can’t quickly understand what your app does, they won’t let their agent use it.

​
Making your app discoverable

Register your app via ERC-8004 so agents can find it. The same registry used for agent identity is used for app discovery. Once registered, agents can query the registry, find your service, and read your SKILL.md to understand how to interact.
