providers (Anthropic, OpenAI, Google, open-source models). It simplifies
credential management and provides usage tracking across tools.</p>

<p>Each tool connects to OpenRouter differently:</p>
<ul>
<li><strong>Claude Code</strong>: set <code>ANTHROPIC_BASE_URL</code> and <code>ANTHROPIC_API_KEY</code> env vars</li>
<li><strong>OpenCode</strong>: configure provider in <code>opencode.json</code></li>
<li><strong>OpenClaw</strong>: configure in agent settings</li>
</ul>
