# Reference



Reference pages are organized by public module.

Start with `ai` for names imported directly from the top-level package, such
as `ai.stream`, `ai.Agent`, and `ai.Tool`. Use sibling module sections such as
`ai.events`, `ai.messages`, `ai.providers`, and `ai.agents` for public
submodule APIs.
