OpenAI-Compatible IDEs (Cline, Roo, Continue)

When to use this guide

Most IDE assistants speak the OpenAI /v1/chat/completions format and let you set a custom base URL. That's the path for Cline, Roo Code, Continue, and similar tools.

Prerequisites

• An sk-cs4-… key from the Codex group in the dashboard.
• For Claude/Anthropic models, create or select a separate key in Basic or Pro.

Cline

1. Open Cline settings → API Provider.
2. Choose OpenAI Compatible.
3. Base URL: https://api.llmsrelay.com/v1
4. API Key: your sk-cs4-… key.
5. Model ID: gpt-5.5

Roo Code

1. Settings → Providers → OpenAI Compatible.
2. Base URL: https://api.llmsrelay.com/v1
3. API Key: your sk-cs4-… key.
4. Model: gpt-5.5

Continue

Edit ~/.continue/config.json:

{
  "models": [
    {
      "title": "OpenAI (LLMsRelay)",
      "provider": "openai",
      "model": "gpt-5.5",
      "apiKey": "sk-cs4-your-key",
      "apiBase": "https://api.llmsrelay.com/v1"
    }
  ]
}

Direct SDK usage

from openai import OpenAI

client = OpenAI(
    api_key="sk-cs4-your-key",
    base_url="https://api.llmsrelay.com/v1",
)

resp = client.chat.completions.create(
    model="gpt-5.5",
    messages=[{"role": "user", "content": "Write a Python quicksort."}],
)
print(resp.choices[0].message.content)

curl https://api.llmsrelay.com/v1/chat/completions \
  -H "Authorization: Bearer sk-cs4-your-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.5",
    "messages": [{"role": "user", "content": "Hello in 3 words"}],
    "stream": true
  }'

Notes

• Use GET /v1/models with your key to enumerate available OpenAI model ids.
• /v1/messages (Anthropic format) is not used with Codex-group keys — stick to the OpenAI endpoints.
• OpenAI usage is billed against your LLMsRelay credits at the published token rates.
