How to Integrate OneHop AI Gateway with Cline in VS Code

Haider Hanif — Sat, 05 Sep 2026 07:05:39 +0000

AI coding agents have become an important part of modern software development. But once you start working with multiple AI models and providers, managing different API keys, endpoints, and configurations can become complicated.

OneHop AI Gateway provides a unified API gateway that can expose supported models through an OpenAI-compatible API interface.

That means you can configure tools such as Cline to communicate with OneHop through a single endpoint.

In this tutorial, we will build the following setup:

Visual Studio Code
|
v
Cline
|
v
OneHop AI Gateway
|
v
Selected Model

By the end of this guide, you will have Cline configured to use OneHop as its AI model gateway.

Note: Model names and availability can change. The model IDs shown in this tutorial are examples and should be verified against the models currently available in your OneHop account.

What You Need

Before starting, make sure you have:

Visual Studio Code installed
An active OneHop account
Permission to create API keys in OneHop
The Cline VS Code extension
A supported OneHop model
Part 1: Install Cline in Visual Studio Code
Step 1: Open the Extensions Marketplace

Start Visual Studio Code.

Open the Extensions panel with:

Ctrl + Shift + X

On macOS:

Cmd + Shift + X

Search for:

CLINE

Look for the official Cline extension published by Autonomous Coding Agent.

Step 2: Install Cline

Open the official Cline extension page.

Click:

Install

After installation, VS Code should show that the extension is installed.

Step 3: Verify the Extension

Open the Cline extension details page.

Verify that:

Cline is installed
VS Code recognizes the extension
Auto Update is enabled if you want automatic updates

Step 4: Open the Cline Panel

After installation, look at the Activity Bar on the left side of VS Code.

Click the Cline robot icon.

The Cline interface should open.

At this point, the Cline extension is ready.

Next, we need a OneHop API key.

Part 2: Create a OneHop API Key
Step 5: Open the OneHop Dashboard

Open the:

API Keys

section.

Click:

Create key

Choose a recognizable name for the key.

For example:

Default key

Create the key.

Step 6: Copy the API Key

After creating the key, copy the secret value.

An API key may look similar to:

oh_live_0KGX...xIj6

The value above is only an example.

Never publish your real API key.

Store the API key securely.

Treat it like a password.

Security Warning

Never publish your real API key in:

GitHub repositories
DEV.to articles
Screenshots
Screen recordings
Public issues
Source code
Frontend applications

For example, never do this:

const apiKey = "oh_live_REAL_SECRET";

Instead, use an appropriate secret-management mechanism or environment-variable strategy for your application.

Part 3: Configure OneHop in Cline

Now we can connect Cline to OneHop.

Step 7: Open Cline Settings

Return to Visual Studio Code.

Open the Cline panel.

Click the Settings gear icon.

Find:

API Provider

Select:

OpenAI Compatible

This tells Cline to communicate with the configured service using an OpenAI-compatible API interface.

Step 8: Configure the OneHop Endpoint

Enter the following configuration.

Setting Value
API Provider OpenAI Compatible
Base URL https://api.onehop.ai/v1
API Key Your OneHop API key
Model ID Your supported OneHop model

The most important value is the Base URL:

https://api.onehop.ai/v1

For example:

API Provider:
OpenAI Compatible

Base URL:
https://api.onehop.ai/v1

API Key:
oh_live_****************

Model ID:
openai/gpt-5.6-terra

Example model identifiers may include:

openai/gpt-5.6-terra
openai/gpt-5.6-sol
anthropic/claude-opus-5

Use the exact model identifier currently supported by your OneHop account.

After entering the configuration, click:

Done

Your Final Cline Configuration

The configuration should now conceptually look like this:

API Provider
|
+-- OpenAI Compatible

Base URL
|
+-- https://api.onehop.ai/v1

API Key
|
+-- oh_live_****************

Model ID
|
+-- openai/gpt-5.6-terra
Part 4: Test the Integration

Now let's verify the connection.

Start with a simple coding task.

For example, ask Cline:

Create a simple TypeScript function that reverses a string.

Explain the implementation and include a small test.

If Cline successfully responds, the basic connection is working.

For a more realistic test, give it a project-inspection task:

Inspect this project structure and tell me:

What framework this project uses
Where the main application entry point is
Which file I should edit to add a new API route

Do not change any files yet.

This is a useful test because it exercises more of Cline's normal workflow.

Troubleshooting
Cline Request Failed

Start by checking these three values:

Base URL
API Key
Model ID

Make sure the Base URL is exactly:

https://api.onehop.ai/v1

Check for:

Extra spaces
Incorrect spelling
Incorrect URL paths
A missing API key
An incorrect model identifier
Authentication Error

If Cline reports an authentication error, verify that:

The API key is correct
The key is active
You copied the complete value
There are no accidental spaces
You did not include quotation marks

Correct:

oh_live_XXXXXXXX

Incorrect:

"oh_live_XXXXXXXX"
Model Not Found

Model identifiers must match the model identifier expected by the gateway.

For example:

openai/gpt-5.6-terra

is different from:

gpt-5.6-terra

Always use the exact model identifier currently provided by OneHop.

Gateway Works but the Model Does Not

If the gateway is reachable but the model request fails, possible causes include:

Model availability
Account permissions
Usage or quota limits
Incorrect model ID
Provider-side issues

Check your OneHop account and verify that the selected model is available.

Recommended Architecture

For a simple development setup:

+----------------------+
| Visual Studio Code |
+----------+-----------+
|
v
+----------------------+
| Cline |
+----------+-----------+
|
v
+----------------------+
| OneHop Gateway |
+----------+-----------+
|
v
+----------------------+
| Selected Model |
+----------------------+

The advantage is that your editor connects to one gateway rather than requiring your development workflow to be rebuilt around each individual model provider.

Using Multiple Models

A gateway-based workflow can also make experimentation easier.

Conceptually:

                +--> Primary Model
                |

VS Code --> Cline -->+--> Coding Model
|
+--> Backup Model

The exact routing and model capabilities depend on the models and features currently available through your gateway.

Security Best Practices

Never Expose Your API Key

When taking screenshots, replace the real key with a masked value:

oh_live_0KGX••••••••xIj6

Never show the complete credential.

Don't Hardcode Secrets

Avoid:

const apiKey = "oh_live_REAL_SECRET";

Use a secure environment-variable or secret-management approach instead.

Rotate Exposed Credentials

If you accidentally publish an API key:

Treat the key as compromised.
Revoke or rotate it.
Generate a replacement key.
Update your local configuration.
Remove the exposed credential from public repositories and documentation.
Quick Configuration Checklist

Before considering the integration complete, verify:

[ ] Visual Studio Code is installed
[ ] Cline is installed
[ ] Cline panel opens successfully
[ ] OneHop account is ready
[ ] OneHop API key has been created
[ ] API key is stored securely
[ ] API Provider is OpenAI Compatible
[ ] Base URL is https://api.onehop.ai/v1
[ ] Model ID is correct
[ ] Test request succeeds
Complete Example

A conceptual configuration can be represented as:

provider: OpenAI Compatible
base_url: https://api.onehop.ai/v1
api_key: oh_live_****************
model: openai/gpt-5.6-terra

The API key is intentionally masked.

Do not replace the masked value with a real secret when publishing this article.

Frequently Asked Questions
Can I change models after configuring OneHop?

Yes, when another model is supported by your OneHop account, you can generally select it by changing the model identifier used by your Cline configuration.

Do I need a different API key for every model?

With the gateway approach described in this tutorial, Cline uses the OneHop credential for the gateway connection.

Why does my model ID not work?

Check the exact model identifier currently supported by OneHop.

Do not assume that a model name from an older tutorial is still available.

Can I publish my API key in a tutorial screenshot?

No.

Never publish the complete key.

Always mask secrets before publishing screenshots or screen recordings.

Final Takeaway

The integration comes down to three core configuration values:

Provider
↓
OpenAI Compatible

Base URL
↓
https://api.onehop.ai/v1

Model
↓
Your supported OneHop model

The complete workflow is:

Visual Studio Code
↓
Cline
↓
OneHop AI Gateway
↓
Selected Model

Once configured, Cline can communicate with your OneHop gateway through its OpenAI-compatible endpoint.

This gives developers a straightforward way to experiment with supported AI models while keeping the editor-side setup simple.

Conclusion

Cline and OneHop can be connected with a relatively simple OpenAI-compatible configuration.

The key settings are:

API Provider: OpenAI Compatible

Base URL:
https://api.onehop.ai/v1

API Key:
Your OneHop secret key

Model ID:
Your supported model

After saving the settings, run a small test task in Cline to verify the connection.

And before publishing your article, check every screenshot for API keys, tokens, account identifiers, or other private information.

How to Set Up Your OneHop API Key in Cursor and Cline: A Step-by-Step Guide

If you're using modern AI development tools like Cursor, Cline, Claude Code, or Cherry Studio, managing multiple API keys across different providers (OpenAI, Anthropic, DeepSeek, Google, etc.) can quickly become messy and expensive.

OneHop acts as a unified AI Gateway, letting you access hundreds of AI models through a single API key and an OpenAI-compatible Base URL (https://api.onehop.ai/v1).

In this short guide, we’ll walk through how to generate your OneHop API key and configure it in Cursor and Cline (VS Code extension) in under 3 minutes.

1. Get Your OneHop API Key

Before configuring your tools, you need to retrieve your credentials from OneHop:

Log in to your OneHop Dashboard.
Navigate to the API Keys section.
Click Create New Key.
Copy your generated key (it usually starts with oh_...). Save it securely, as you won't be able to see it again.

2. Setting Up OneHop in Cursor

Cursor is an AI-first code editor built on VS Code. Because OneHop is fully OpenAI API-compatible, setting it up in Cursor is simple.

Steps:

Open Cursor.
Go to Settings (Click the gear icon in the top right or press Ctrl + , / Cmd + ,).
Select Cursor Settings -> Models.
Scroll down to the OpenAI API Key section:
- Override OpenAI Base URL: Toggle this on and set it to:
```
 [https://api.onehop.ai/v1](https://api.onehop.ai/v1)
```

OpenAI API Key: Paste your OneHop key (oh_...).
1. Under Model Names, enable or add the models you wish to route through OneHop, such as:
openai/gpt-5.6-sol
anthropic/claude-opus-5
anthropic/claude-sonnet-5
1. Save your settings and run a test query in the Cursor AI Chat sidebar to confirm everything is working!

3. Setting Up OneHop in Cline (VS Code Extension)

Cline is an autonomous coding assistant in VS Code that supports custom OpenAI-compatible endpoints.

Steps:

Open VS Code and open the Cline panel.
Click the Settings Gear icon inside the Cline extension panel.
In the API Provider dropdown, select OpenAI Compatible.
Fill in the following details:
- Base URL: https://api.onehop.ai/v1
- API Key: Paste your OneHop key (oh_...).
- Model ID: Enter the model string you want to use (e.g., openai/gpt-5.6-sol, anthropic/claude-opus-5, or anthropic/claude-sonnet-5).
Click Done / Save.
Submit a quick prompt in Cline to verify that responses are streaming correctly.

Conclusion

Using OneHop as your central AI gateway simplifies model management and keeps your workflow clean across all your favorite IDEs and coding agents—whether you're using Cursor, Cline, Claude Code, Cherry Studio, or Hermes.
