# Sai API

> Send Sai a task in plain English over HTTP; Sai runs it on a Windows computer we host and returns the result. These are the Sai API docs, one Markdown file per page.

## Docs

### Get started

- [Sai API](/documentation/index.md): What the Sai API is and how a request flows through it.
- [Quickstart](/documentation/quickstart.md): From sign-in to a finished task in one sitting.

### Concepts

- [Computers](/documentation/concepts/computers.md): Where Sai works, and how the API picks one.
- [Sessions](/documentation/concepts/sessions.md): One conversation per computer on the API channel.
- [Approvals](/documentation/concepts/approvals.md): Two classes of approval, and how to answer each.
- [Billing and limits](/documentation/concepts/billing-and-limits.md): What a request costs, what a free account gets, and the rate limits.

### Coding agents

- [Claude Code](/documentation/coding-agents/claude-code.md): Give Claude Code a computer by adding the Sai MCP server.
- [Codex](/documentation/coding-agents/codex.md): Add the Sai MCP server to OpenAI Codex.
- [Cursor](/documentation/coding-agents/cursor.md): Add the Sai MCP server to Cursor.
- [Watch Sai work](/documentation/coding-agents/live-view.md): The live view the Sai MCP server shows for every task, inside your coding agent or in a browser.
- [Channels (research preview)](/documentation/coding-agents/channels.md): Let Sai push results into Claude Code instead of being polled.

### API reference
