How to Connect Qwen 3.7 to Claude Code CLI & Cursor (Anthropic Protocol Setup Guide)

# Export APIVALE proxy base URL and API key
export ANTHROPIC_BASE_URL="https://apivale.com/v1"
export ANTHROPIC_API_KEY="sk-apivale-your-api-key"

# Launch Claude Code CLI with target model
claude --model infer/qwen3.7-max

With the official release of Qwen 3.7 and its flagship successor Qwen 3.8 (see our guide on how to connect Qwen 3.8 to Claude Code CLI), Alibaba Cloud has ushered in what developers across Reddit, Hacker News, and X are calling the “Agent Era.” Demonstrating SOTA performance on benchmarks like SWE-bench Pro and Terminal Bench 2.0, Qwen 3.7 excels at long-horizon autonomous coding—running multi-hour terminal loops, automated debugging, and multi-file project refactoring without human intervention.

While Anthropic’s flagship Claude Sonnet 5 and OpenAI’s newly unveiled GPT-6 Astra & Sol (see our GPT-6 Astra Price Guide and GPT-6 Sol vs Qwen 3.7 Max Benchmark) push frontier reasoning boundaries, Qwen 3.7 has captured global developer attention as an ultra-efficient, cost-effective coding engine with native Anthropic API protocol compatibility.

In this guide, we show you how to configure Anthropic’s Claude Code CLI and terminal agent tools to run directly on Qwen 3.7 using the ANTHROPIC_BASE_URL environment setting, routed through APIVALE’s global high-concurrency gateway. (Looking to enforce minimal, YAGNI-style code generation and eliminate bloat?

Why Route Claude Code CLI from Sonnet 5 to Qwen 3.7?

Anthropic’s Claude Code CLI powered by Claude Sonnet 5 is arguably the most productive developer tool released in recent years. However, running long-horizon autonomous tasks creates two persistent hurdles:

1. Token Cost Burn: Terminal agents continuously resubmit workspace file trees, lint outputs, and bash execution logs back into the context window. In a 2-hour debugging session, Claude Code can easily consume 20M+ tokens. Using official Claude Sonnet 5 rates ($3.00/$15.00), a single complex issue resolution can cost $30–$50.
2. Rate Limit Throttling: Official Tier 1 and Tier 2 API accounts frequently hit 429 Rate Limit Exceeded during heavy tool-calling loops, halting autonomous task completion midway through an edit.

[!TIP] Monitoring Agent Token Burn on Windows: While routing Claude Code CLI to Qwen 3.7 Max dramatically lowers your per-token cost, running continuous agent debugging loops still burns millions of tokens in the background. Windows developers can track real-time terminal consumption using our CodexBar Windows Setup Guide to monitor quota health and avoid rate limit pauses.

[!NOTE] Looking for Lightweight Subagent Routing? If you are considering Anthropic’s new compact model, beware of the 500% tiered billing penalty beyond 100K tokens. Check our breakdown on Claude Haiku 5.5: Pricing & API Alternatives to see how Qwen 3.7 Max and DeepSeek-V4 deliver flat-rate stability.

By setting ANTHROPIC_BASE_URL to point to APIVALE, you can route Claude Code directly to Qwen 3.7-Max. You gain 80% token cost savings ($0.60 Input / $2.40 Output), near-zero throttling, and unhindered long-horizon reasoning.

For developers who also run coding sessions inside Cursor IDE, replacing the default $20 subscription with pay-as-you-go Qwen 3.7 access provides identical cost savings. Explore our Cursor Pro vs custom API key analysis to see how custom endpoints optimize monthly editor budgets.

Step-by-Step Environment Setup

1. macOS & Linux Configuration

Add the following environment variables to your shell profile (~/.zshrc or ~/.bashrc) to make your Qwen 3.7 routing permanent:

# Open profile editor
nano ~/.zshrc

# Add APIVALE Qwen 3.7 routing configuration
export ANTHROPIC_BASE_URL="https://apivale.com/v1"
export ANTHROPIC_AUTH_TOKEN="apivale-key-xxxxxxxxxxxxxxxx"
export ANTHROPIC_MODEL="infer/qwen3.7-max"

# Save and reload
source ~/.zshrc

# Run Claude Code CLI
npx @anthropic-ai/claude-code

2. Windows PowerShell Setup

For Windows developers using PowerShell:

# Set environment variables for the current session
$env:ANTHROPIC_BASE_URL="https://apivale.com/v1"
$env:ANTHROPIC_AUTH_TOKEN="apivale-key-xxxxxxxxxxxxxxxx"
$env:ANTHROPIC_MODEL="infer/qwen3.7-max"

# Execute Claude Code CLI
npx @anthropic-ai/claude-code

Advanced: Dynamic Model Switching Router (Node.js & Python)

If your development workflow requires switching between Claude Sonnet 5 for architect-level planning and Qwen 3.7-Max for routine refactoring, you can run a lightweight local proxy router, pair upstream System 1 classifiers like the TypeSafe Jev AI model for deterministic intent routing, or offload high-volume terminal execution to the newly released DeepSeek V4.1 Flash 1017 Checkpoint Guide (scoring 77.0 on DeepSWE v1.1).

TypeScript / Node.js Router Script

Create a qwen-claude-router.ts script to log token telemetry and transparently forward requests to APIVALE:

import express, { Request, Response } from 'express';
import axios from 'axios';

const app = express();
const PORT = 3005;
const APIVALE_GATEWAY = 'https://apivale.com/v1';

app.use(express.json());

app.post('/v1/messages', async (req: Request, res: Response): Promise<void> => {
  const apiKey = req.headers['x-api-key'] || req.headers['authorization'];

  // Override model to Qwen 3.7-Max if requesting default Claude model
  const payload = {
    ...req.body,
    model: req.body.model.includes('claude') ? 'infer/qwen3.7-max' : req.body.model
  };

  console.log(`[Claude Code Router] Redirecting model '${req.body.model}' -> '${payload.model}'`);

  try {
    const upstreamRes = await axios.post(`${APIVALE_GATEWAY}/messages`, payload, {
      headers: {
        'x-api-key': apiKey,
        'content-type': 'application/json',
        'anthropic-version': req.headers['anthropic-version'] || '2023-06-01'
      },
      responseType: payload.stream ? 'stream' : 'json'
    });

    if (payload.stream) {
      res.setHeader('Content-Type', 'text/event-stream');
      upstreamRes.data.pipe(res);
    } else {
      res.json(upstreamRes.data);
    }
  } catch (err: any) {
    console.error(`[Router Error] Failed to route request: ${err.message}`);
    res.status(err.response?.status || 500).json(err.response?.data || { error: 'Gateway Error' });
  }
});

app.listen(PORT, () => {
  console.log(`Qwen 3.7 Anthropic Router online at http://localhost:${PORT}`);
});

To connect your CLI to this local router:

export ANTHROPIC_BASE_URL="http://localhost:3005/v1"
export ANTHROPIC_AUTH_TOKEN="apivale-key-xxxxxxxx"
npx @anthropic-ai/claude-code

Developer FAQ

Q: Does Claude Code CLI natively accept Qwen 3.7 as a backend model?
A: Yes. Because Qwen 3.7 supports the Anthropic API protocol and standard tool-calling schema, setting ANTHROPIC_BASE_URL="https://apivale.com/v1" and ANTHROPIC_MODEL="infer/qwen3.7-max" allows Claude Code CLI to communicate with Qwen 3.7 smoothly without code edits.

Q: Do I need a Chinese phone number (+86) or identity verification to use Qwen 3.7 on APIVALE?
A: No. APIVALE bypasses domestic phone binding and real-name verification walls. You can sign in using GitHub, credit cards, or PayPal, and start making API calls immediately.

Q: How does Qwen 3.7 Max compare to Claude Sonnet 5 in multi-step tool calling?
A: Qwen 3.7 Max was pre-trained specifically for agentic workflows (“Agent Era”), achieving state-of-the-art results on SWE-bench Pro. While Claude Sonnet 5 offers refined interactive reasoning, Qwen 3.7 Max matches it on multi-tool invocations and long-horizon bash executions at 80% lower token cost. For teams evaluating how Qwen 3.7 Max compares to low-cost volume options like Haiku 5.5 and Luna 6, read our Haiku 5.5 vs GPT-6 Luna pricing and benchmark guide.

Q: Will streaming responses and terminal progress spinners work correctly?
A: Yes. APIVALE provides full Server-Sent Events (SSE) streaming compatibility, guaranteeing real-time token rendering and smooth interactive output inside Claude Code.
