Question: How to use such settings in Claude Code?

Answer:

The file you showed is the user-level configuration file for Claude Code (the Anthropic coding agent/CLI tool, often used in terminal or via the VS Code extension).

Place this file at:

~/.claude/settings.json (Linux/macOS)
%USERPROFILE%\.claude\settings.json (Windows)

Claude Code automatically reads this file (both the CLI version and the official Anthropic VS Code extension respect it in recent versions).

Your current file configures three main things:

{
  "feedbackSurveyState": {
    "lastShownTime": 1753996737780
  },
  "skipDangerousModePermissionPrompt": true,
  "env": {
    "ANTHROPIC_BASE_URL": "https://v2-as.pincc.ai",
    "ANTHROPIC_AUTH_TOKEN": "sk-8a25bb9202a81c57xx",
    "CLAUDE_CODE_ATTRIBUTION_HEADER": "0"
  }
}

What each setting does and how it’s used

env.ANTHROPIC_BASE_URL
Changes the API endpoint Claude Code talks to (instead of official api.anthropic.com).
→ You are pointing it to a reverse proxy / third-party provider / custom Anthropic-compatible server.
env.ANTHROPIC_AUTH_TOKEN
The API key / bearer token sent to that custom endpoint.
→ Format usually starts with sk- (same as official Anthropic keys).
env.CLAUDE_CODE_ATTRIBUTION_HEADER set to "0"
Most likely disables the attribution / “Powered by Claude” header or watermark that some providers force.
skipDangerousModePermissionPrompt: true
Automatically accepts / skips the confirmation prompt when using dangerous tools (file write, shell commands, etc.).
→ Useful for fully automated workflows, but increases risk.

How to make it work

Save the file correctly
Make sure the path is exactly ~/.claude/settings.json (create the .claude folder if it doesn’t exist).
Restart Claude Code sessions
- Terminal: close & reopen terminal, then run claude again
- VS Code extension: reload VS Code window (Ctrl+R or Cmd+R on Mac) or restart the extension
Test it
Run in terminal:
```
claude
```
or use the VS Code sidebar / command palette → “Claude Code”.

If configured correctly you should see no login prompt and it should connect to https://v2-as.pincc.ai instead of Anthropic directly.

Notes / common issues (2026 status)

Some older versions of the VS Code extension ignored ~/.claude/settings.json → make sure you use a recent version of the official Anthropic Claude Code extension.
If it still asks for login → try temporarily setting the same variables in your shell (export ANTHROPIC_BASE_URL=...) before launching, or check GitHub issues for your exact version.
Many proxy providers (LiteLLM, AskSage, 302.ai, custom gateways, etc.) use exactly this settings.json + ANTHROPIC_BASE_URL pattern.

That’s the standard and recommended way to use custom endpoints / keys / behavior tweaks in Claude Code.
