VS Code and other extensions

Editor extensions connect in one of two modes: OpenAI Compatible (address with /v1) or Anthropic (address without /v1).

Claude Code

Install the extension. It reads the same ~/.claude/settings.json as the CLI: set it up following the Claude Code guide and restart the editor.

Cline, Roo Code, Kilo Code

Open the extension panel → settings → API Provider and fill in the fields:

API Provider:        OpenAI Compatible
Base URL:            https://api.claudexia.tech/v1
API Key:             sk_cdx_YOUR_KEY
Model ID:            claude-sonnet-5
Context Window Size: 1000000

Always set the context size: otherwise the extension assumes a 128K model and compacts history too early.

Continue

Open ~/.continue/config.json (on Windows %USERPROFILE%\.continue\config.json) and add a model:

{
  "models": [
    {
      "title": "Claudexia · Claude Sonnet 5",
      "provider": "openai",
      "model": "claude-sonnet-5",
      "contextLength": 1000000,
      "apiBase": "https://api.claudexia.tech/v1",
      "apiKey": "sk_cdx_YOUR_KEY"
    }
  ]
}

New models are picked up when you save the file.

Any other extension

Pick the provider type and use the matching address:

Take model names from the catalog.
