+# OpenCode Zen
+
+## Overview
+
+OpenCode Zen represents a **curated list of models** recommended by the OpenCode team for coding agents. It functions as an optional hosted model access pathway requiring an API key and the `opencode` provider, currently in beta status.
+
+## Setup Instructions
+
+**CLI Configuration (Interactive):**
+
+```bash
+openclaw onboard --auth-choice opencode-zen
+```
+
+**CLI Configuration (Non-Interactive):**
+
+```bash
+openclaw onboard --opencode-zen-api-key "$OPENCODE_ZEN_API_KEY"
+```
+
+**Configuration File:**
+
+```json5
+{
+  env: { OPENCODE_ZEN_API_KEY: "sk-..." },
+  agents: { defaults: { model: { primary: "opencode/claude-opus-4-5" } } },
+}
+```
+
+## Key Details
+
+The service accepts either `OPENCODE_ZEN_API_KEY` or `OPENCODE_API_KEY` for authentication. Users establish their account through Zen's login portal, configure billing information, and retrieve their API credentials from the platform.
+
+## Billing Model
+
+The service operates on a per-request pricing structure. Cost details and usage monitoring are available through the OpenCode dashboard.
