Cline is a VS Code coding assistant with chat, terminal integration, and multi-file editing. Configure it to use Passy so you can route requests through a single API.

​
Quick Configuration

Use this setup for gpt-4o, gpt-4o-mini, gemini-1.5-pro, gemini-1.5-flash, passy/deepseek-v3, passy/mistral-nemo, and other models returned by https://api.passy.ai/v1/models.
1

Open Cline Settings

  1. Open VS Code.
  2. Run Cline: Open Settings from the Command Palette.

Set Provider

  1. Select OpenAI.
  2. Set Base URL to https://api.passy.ai/v1.
  3. Paste your Passy API key from dash.passy.ai/keys.

Choose Model

Start with gpt-4o-mini for a fast default, or switch to another model ID from the live models endpoint.
{
  "cline.apiProvider": "openai",
  "cline.openai": {
    "apiKey": "sk-passy-your-api-key",
    "baseURL": "https://api.passy.ai/v1"
  },
  "cline.defaultModel": "gpt-4o-mini"
}
For the OpenAI-compatible setup, keep /v1 in the base URL.
Use exact model IDs as returned by the API.

Browse the public catalog at passy.ai/models or fetch the live OpenAI-compatible list from https://api.passy.ai/v1/models.

​
Verification

After saving your settings:
  1. Open the Cline panel.
  2. Start a new chat.
  3. Ask: What model are you using?
  4. Ask: Write a hello world function in Python.
You should get a normal response from the configured Passy model. To verify that your API key and model list are working outside VS Code: 
curl -H "Authorization: Bearer $PASSY_API_KEY" \
  https://api.passy.ai/v1/models

​
Common Configurations

​
Fast Default

{
  "cline.apiProvider": "openai",
  "cline.openai": {
    "apiKey": "${env:PASSY_API_KEY}",
    "baseURL": "https://api.passy.ai/v1"
  },
  "cline.defaultModel": "gpt-4o-mini"
}

​
Claude Setup

{
  "cline.apiProvider": "anthropic",
  "cline.anthropic": {
    "apiKey": "${env:PASSY_API_KEY}",
    "baseURL": "https://api.passy.ai"
  },
  "cline.defaultModel": "claude-3-sonnet-20240229"
}

​
DeepSeek Setup

{
  "cline.apiProvider": "openai",
  "cline.openai": {
    "apiKey": "${env:PASSY_API_KEY}",
    "baseURL": "https://api.passy.ai/v1"
  },
  "cline.defaultModel": "passy/deepseek-v3"
}

​
Troubleshooting

  1. Check that the provider matches the base URL format.
  2. For OpenAI-compatible config use https://api.passy.ai/v1.
  3. For Anthropic-compatible config use https://api.passy.ai.
  4. Confirm the model ID exists in https://api.passy.ai/v1/models.
  1. Regenerate or copy the key again from dash.passy.ai/keys.
  2. Reload VS Code after changing environment variables.
  3. Test the key manually with curl against https://api.passy.ai/v1/models.
Make sure the provider is anthropic and the base URL is https://api.passy.ai without /v1.
Make sure the provider is openai and the base URL is https://api.passy.ai/v1.
Check Cline’s approval prompts inside VS Code and confirm the workspace is trusted. If terminal actions are blocked, review your Cline and VS Code terminal permissions.

​
Best Practices

Use Env Vars

Keep the API key in ${env:PASSY_API_KEY} instead of hardcoding it in settings.

Use Exact IDs

Copy model IDs exactly as returned by the Passy models endpoint.

Pick the Right Provider

Use openai for /v1 models and anthropic for Claude-style requests.

Start with Fast Models

gpt-4o-mini and passy/mistral-nemo are good default starting points.
