Claude API examples

Copy-paste ready configurations for every Claude-compatible tool. Set your base URL to https://api.lumosel.vip and use your Lumosel API key.

Claude Code

Configuration file: ~/.claude/settings.json

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.lumosel.vip",
    "ANTHROPIC_AUTH_TOKEN": "lumo_live_YOUR_KEY",
    "ANTHROPIC_MODEL": "claude-opus-4-8"
  }
}

Restart Claude Code after editing. Pin ANTHROPIC_MODEL so Claude Code never auto-selects a model the gateway doesn't serve.

Cline / Roo Code

Configuration file: VS Code extension settings

// In VS Code settings.json or Cline/Roo Code settings:
"cline.anthropicBaseUrl": "https://api.lumosel.vip",
"cline.apiKey": "lumo_live_YOUR_KEY"

Set the model to claude-opus-4-8, claude-sonnet-4.5, or claude-haiku-4.5 in the extension's model picker.

opencode

Configuration file: ~/.config/opencode/config.toml

[provider.anthropic]
base_url = "https://api.lumosel.vip"
api_key = "lumo_live_YOUR_KEY"

opencode reads the Anthropic environment variables. Restart after setting.

Zed

Configuration file: ~/.config/zed/settings.json

{
  "assistant": {
    "provider": {
      "name": "anthropic",
      "api_url": "https://api.lumosel.vip"
    }
  }
}

Set ANTHROPIC_API_KEY=lumo_live_YOUR_KEY as an environment variable before launching Zed.

Any Anthropic-compatible tool

Configuration file: Environment variables

export ANTHROPIC_BASE_URL="https://api.lumosel.vip"
export ANTHROPIC_API_KEY="lumo_live_YOUR_KEY"

Any tool that reads the Anthropic environment variables works. Set these in your shell profile or .env file.
