Cline Setup Guide

Configure the Cline (formerly Claude Dev) VS Code extension to call models through our endpoint.

Verification status — last reviewed 2026-09-20

  • Consistent with Quick Start: the base URL, the authorization header and the model IDs below are taken from the same sources as the Quick Start guide, and every model ID listed is one we currently sell.
  • Not verified: the setup steps on this page have not been re-run end to end against Cline by us, and no Cline version is recorded. Streaming output, tool calling (file edits, terminal commands) and image input have not been tested individually for this client.
  • Treat this page as a configuration walkthrough rather than a compatibility guarantee. If a step does not match your Cline version, follow what Cline's own UI shows and send us the difference — we will re-test and update this page.

📱 What is Cline?

Cline (formerly Claude Dev) is a powerful VS Code extension that brings AI assistance directly into your editor. It can read files, edit code, execute terminal commands, and help with complex development tasks.

Key features:

  • File and folder operations
  • Terminal command execution
  • Browser automation support
  • Multi-model support (Claude, GPT, Gemini, etc.)
  • Inline code editing with diff view

Install from the VS Code Marketplace.

⚙️ Configuration Steps

Step 1: Open Cline Settings

Click the Cline icon in the VS Code sidebar, then click the settings gear icon (⚙️) in the Cline panel header.

Step 2: Select API Provider

In the Settings dialog, find the API Provider dropdown and select OpenAI Compatible.

💡 Important: Even when using Claude models, select "OpenAI Compatible" as the provider type. Our endpoint speaks the OpenAI chat-completions format, and that is the format Cline's OpenAI Compatible provider sends — which is why this is the provider to pick, regardless of which model you end up calling.

Step 3: Configure Base URL

In the Base URL field, enter:

https://jzstoken.com/api/v1

Step 4: Add Your API Key

In the API Key field, paste your API key from the dashboard:

sk-your-api-key-here

Get your API key from the API Keys page in your dashboard.

Step 5: Select a Model

In the Model field, enter the exact model ID you want to use. Common choices:

claude-sonnet-5

Latest Claude Sonnet — Best balance of speed and capability

claude-opus-5

Claude Opus — Highest capability, best for complex tasks

claude-haiku-4-5-20251001

Claude Haiku — Fastest, most cost-effective

gpt-5.6-terra

GPT-5 — OpenAI's latest flagship model

See the full model pricing page for all available models and current provider-grouped rates.

Step 6: Save and Test

Click Save to apply the configuration. Start a new conversation in Cline to test the connection.

🤖 Using Claude Models

All Claude models work through the OpenAI Compatible provider. Simply enter the model ID directly:

  • claude-sonnet-5
  • claude-opus-5
  • claude-fable-5
  • claude-haiku-4-5-20251001
⚠️ Key type matters: a key created for jzs-max-3.0 can only call that model. For other Claude models, use a Standard key. Check your key type in the dashboard.

🔄 Switching Between Models

You can switch models at any time:

  1. Click the settings gear icon in the Cline panel
  2. Change the Model field to a different model ID
  3. Click Save
  4. The new model takes effect immediately in new conversations

Each model has different rates. Check the model pricing page for the current cost comparison.

📋 Example Configuration

Here's a complete working configuration:

API Provider

OpenAI Compatible

Base URL

https://jzstoken.com/api/v1

API Key

sk-xxxxxxxxxxxxxx

Model

claude-sonnet-5

🔧 Troubleshooting

  • Connection Failed? — Check your network connection, verify the Base URL is exactly https://jzstoken.com/api/v1 (no trailing slash), confirm your API key is correct.
  • 401 Unauthorized? — Verify your API key is active in the dashboard, check that your balance is sufficient.
  • 403 Model not supported? — Check that your key type matches the model. A jzs-max-3.0 key cannot call anything else.
  • Model not responding? — Try a different model ID. Make sure the model name is spelled exactly as shown in the catalog (case-sensitive).
  • Cline not showing up? — Restart VS Code after installation. Check that the extension is enabled in the Extensions panel.

💡 Tips for Best Results

  • Start with Sonnet: claude-sonnet-5 offers the best balance of cost and capability for most coding tasks.
  • Use Opus for complex work: Switch to claude-opus-5 when dealing with complex architecture decisions or refactoring.
  • Save with Haiku: For simple edits and quick questions, claude-haiku-4-5-20251001 is fast and cost-effective.
  • Monitor usage: Check your usage dashboard to track token consumption and costs.
