Claude Code

Anthropic's terminal coding agent

Anthropic Anthropic Messages macOSLinuxWindows

Claude Code is Anthropic's command-line coding agent: it reads your code, edits files, runs shell commands, and commits to Git from the terminal. It suits engineers who work in the terminal and want an agent that operates directly on the local repo. It talks the Anthropic Messages protocol (/v1/messages).

Skip it — one-line setup

The script installs Claude Code from its official source, writes the gateway settings into the tool's own config file (backing up any existing one) and runs a live check. It asks for your gateway key, or take it from --key / --key-file. --uninstall restores exactly what it wrote.

shell
curl -fsSL https://quantoport.com/agents/claude-code/setup | bash -s claude-code

1 · Install

Install Claude Code from its own official source.

install
curl -fsSL https://claude.ai/install.sh | bash
# or via npm:
npm install -g @anthropic-ai/claude-code
# Windows (PowerShell):
irm https://claude.ai/install.ps1 | iex

2 · Configure — point it at QuantoPort

Gateway base URL https://quantoport.com; get your key from the console.

config
International site https://quantoport.com (native Anthropic format, supported directly):
1) Set environment variables:
   export ANTHROPIC_BASE_URL=https://quantoport.com
   export ANTHROPIC_AUTH_TOKEN=<your gateway key>
   (if your gateway reads x-api-key instead, use export ANTHROPIC_API_KEY=<your gateway key>)
2) Or add an env block to ~/.claude/settings.json (more reliable for background agents):
   { "env": { "ANTHROPIC_BASE_URL": "https://quantoport.com", "ANTHROPIC_AUTH_TOKEN": "<your gateway key>" } }
3) Run claude and check /status: the "Anthropic base URL" line should show the gateway.
CN site https://api.shinlinkai.com exposes only the OpenAI format, while Claude Code requires the Anthropic /v1/messages protocol; it needs protocol conversion and is not supported yet.

3 · Verify

One request proves you are on our channel.

verify
curl -sS -w '\n%{http_code}\n' -X POST "$ANTHROPIC_BASE_URL/v1/messages" -H "Authorization: Bearer $ANTHROPIC_AUTH_TOKEN" -H "anthropic-version: 2023-06-01" -H "content-type: application/json" -d '{"model":"claude-sonnet-4-6","max_tokens":1,"messages":[{"role":"user","content":"."}]}'
# A JSON body starting with {"id":"msg_ means the gateway is reachable; or just run: claude -p "hello"

4 · Common pitfalls

  • ANTHROPIC_AUTH_TOKEN is sent as Authorization: Bearer; ANTHROPIC_API_KEY is sent as x-api-key — using the wrong one returns 401.
  • A settings.json env block overrides shell exports; prefer it for background agents.
  • The gateway credential overrides a saved claude.ai login; confirm with /status and run /logout if needed.
  • On Windows set $env:ANTHROPIC_BASE_URL="..."; use the model names your gateway actually serves.
