How to Use Claude 3.5 Sonnet in Cline (VS Code) with Low-Cost Custom API Gateway

Cline (formerly known as Claude Dev) has quickly become one of the most capable open-source autonomous coding agents inside Visual Studio Code. Unlike standard code completion extensions, Cline can inspect your workspace, create and edit multi-line files, execute terminal commands, and solve complex architectural refactors automatically.

However, powering Cline with Anthropic's flagship Claude 3.5 Sonnet model directly through official retail API billing can quickly become expensive, especially when building large-scale projects that generate thousands of context tokens per prompt.

By configuring Cline to use a high-performance unified gateway like AI Supermarket, developers can slash token expenses by 50% to 70%, bypass strict regional payment restrictions, and maintain blazing fast coding speeds.


๐Ÿš€ Why Connect Cline to AI Supermarket?โ€‹

When running an autonomous agent like Cline, context windows expand rapidly as the agent reads repository trees and unit test logs. Connecting to AI Supermarket provides three immediate benefits:

  1. Substantial Cost Reductions: Access genuine Claude 3.5 Sonnet, GPT-4o, and Gemini models at competitive wholesale rates.
  2. Zero Payment Roadblocks: Top up via flexible payment methods without worrying about international credit card declines.
  3. No Artificial Rate Limits: Enterprise-grade multi-channel load balancing prevents disruptive 429 Too Many Requests interruptions during continuous coding tasks.

๐Ÿ› ๏ธ Step-by-Step Cline Configuration Guideโ€‹

Follow these simple steps to configure Cline with AI Supermarket in VS Code:

Step 1: Install the Cline Extensionโ€‹

  1. Open Visual Studio Code.
  2. Press Ctrl + Shift + X (or Cmd + Shift + X on macOS) to open the Extensions marketplace.
  3. Search for Cline (by Saoud Rizwan / Roo Code) and click Install.

Step 2: Obtain Your AI Supermarket API Keyโ€‹

  1. Visit AI Supermarket (aisupermarket.work) and register your developer account.
  2. Navigate to the API Keys section in your dashboard.
  3. Click Add New Key, assign a name (e.g., Cline-VSCode), and copy the generated token (sk-...).

Step 3: Configure API Provider in Cline Settingsโ€‹

  1. Open the Cline panel in your VS Code sidebar.
  2. Click the Gear (Settings) icon at the top of the Cline window.
  3. In the API Provider dropdown, select OpenAI Compatible.
  4. Fill in the following parameters:
    • Base URL: https://www.cheapertoken.work/v1
    • API Key: sk-your-ai-supermarket-api-key
    • Model ID: claude-3-5-sonnet-20241022 (or gpt-4o, deepseek-chat)

๐Ÿ’ป Verification & Hello World Testโ€‹

To confirm that your custom gateway is configured properly, you can also run a quick Python verification script outside VS Code:

from openai import OpenAI

# Initialize client pointing to AI Supermarket gateway
client = OpenAI(
api_key="sk-your-ai-supermarket-key",
base_url="https://www.cheapertoken.work/v1"
)

response = client.chat.completions.create(
model="claude-3-5-sonnet-20241022",
messages=[
{"role": "system", "content": "You are an autonomous senior software engineer."},
{"role": "user", "content": "Initialize a TypeScript microservice structure with Dockerfile."}
],
max_tokens=500
)

print(response.choices[0].message.content)

โ“ Frequently Asked Questions (FAQ)โ€‹

Does Cline support streaming completions through custom endpoints?โ€‹

Yes! AI Supermarket's /v1 gateway fully supports real-time SSE (Server-Sent Events) streaming, enabling instant line-by-line code generation in Cline.

What if I get an "Authentication Error" in VS Code?โ€‹

Double check that:

  • Your API key starts with sk- and contains no extra leading/trailing whitespace.
  • The Base URL is exactly https://www.cheapertoken.work/v1 (ensure /v1 is included).
  • Your account at aisupermarket.work has active quota balance.
