description	Configure and use Duel Agents model routing in Claude Code. Requires a Duel API key from duelagents.com. Routes all LLM traffic through duelagents.com/v1.

Duel Agents

Duel Agents runs your prompts against multiple models and picks the cheapest answer that still passes quality checks. Every request must use your Duel API key. Never substitute a direct Anthropic or OpenAI key.

Setup

1. Subscribe and create an API key at https://duelagents.com/dashboard/settings
2. Run: npx @duel-agents/install claude-code
3. Or set manually in ~/.claude/.env:

ANTHROPIC_BASE_URL=https://duelagents.com/v1
ANTHROPIC_API_KEY=duel_yourprefix_yoursecret

4. Restart Claude Code

Verify

npx @duel-agents/install doctor

Build on top

Use @duel-agents/sdk in your own tools. Always pass apiKey from your Duel dashboard.

import { DuelClient } from "@duel-agents/sdk";

const duel = new DuelClient({ apiKey: process.env.DUEL_API_KEY! });
await duel.chat.completions.create({
  model: "duel-auto",
  messages: [{ role: "user", content: "Hello" }],
});
