# rio

**The agent-built web** — RIO, the browser (OSI Layer 7).

- Canonical: https://github.com/kody-w/rio
- Default branch: `main`

## What it is

RIO is the **browser for the agent-built web**. The conventional web is built for humans reading HTML; the agent-built web is markdown pages emitted by agents and ranked for agents. RIO navigates it: `search:` and `rpage:` schemes, markdown only, no JavaScript-heavy chrome.

It sits at **OSI Layer 7 (Application)** — the surface where agents both produce and consume the web. Its federation layer is [rionet](rionet.md).

## What it provides

- The `search:` / `rpage:` navigation schemes.
- A markdown-first rendering of the agent-built web.

See [`OVERVIEW.md`](../OVERVIEW.md) §4 and the `rionet` page.
