# Dify Agent runtime

Dify Agent hosts Agenton-composed Pydantic AI runs behind a FastAPI API. Its
source code stays under `src/dify_agent`, while framework-neutral Agenton code
stays under `src/agenton` and `src/agenton_collections`.

See the [operations guide](guide/index.md) for local server behavior and the
[run API](api/index.md) for request and event schemas.
