Claude Code

Claude Code is Anthropic's official CLI assistant. Pointing it at PulseNeko Bridge is two env vars.

Prerequisites

• Claude Code installed (claude --version works)
• A key in a group containing Anthropic models (recommended: aws-q)

Method A: environment variables

macOS / Linux

Append to ~/.zshrc / ~/.bashrc:

export ANTHROPIC_BASE_URL=https://bridge.pulseneko.com
export ANTHROPIC_AUTH_TOKEN=sk-your-key
export CLAUDE_CODE_ATTRIBUTION_HEADER=0

Open a new terminal, run claude.

Windows (PowerShell)

[Environment]::SetEnvironmentVariable("ANTHROPIC_BASE_URL", "https://bridge.pulseneko.com", "User")
[Environment]::SetEnvironmentVariable("ANTHROPIC_AUTH_TOKEN", "sk-your-key", "User")
[Environment]::SetEnvironmentVariable("CLAUDE_CODE_ATTRIBUTION_HEADER", "0", "User")

Fully restart PowerShell / VS Code, run claude.

Method B: settings.json

For multi-account workflow:

• macOS / Linux: ~/.claude/settings.json
• Windows: %userprofile%\.claude\settings.json

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://bridge.pulseneko.com",
    "ANTHROPIC_AUTH_TOKEN": "sk-your-key",
    "CLAUDE_CODE_ATTRIBUTION_HEADER": "0",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1",
    "CLAUDE_CODE_DISABLE_TERMINAL_TITLE": "1"
  }
}

Multi-account switching

Use CC Switch. API Keys has a CC Switch one-click import button.

Recommended models

Model	Best for
claude-haiku-4-5	Quick chat, tiny edits
claude-sonnet-4-6	Daily driver
claude-opus-4-7	Heavy refactors, planning
claude-opus-4-7-thinking	4.7 + extended thinking

Switch in-session with /model <name>.

Which group carries which model

Each model card on the Model Catalog tags its Group. The Claude family is spread across default / anthropic / cc / aws-q / windsurf etc., with prices that vary substantially. Pick the combination by the catalog tag and visible price.
