Claude Code

Anthropic's official terminal CLI. Point it at ByteSeek with two environment variables — five minutes, done.

Product intro on the Anthropic website; commands and usage in the official docs.

Prerequisites

Claude Code installed (claude --version prints a version)
A key for an Anthropic-format group created on the API Keys page (format guidance in API Endpoints)

Configure (one click from the console)

No hand-written config needed — the console generates it for your key:

Open the API keys page, and in the key row's Actions column click More → Use key;
The dialog opens on the Claude Code tab — switch between macOS / Linux, Windows CMD, PowerShell for your system and copy the generated content.

Use key dialog, Claude Code tab — The "Use key" dialog on the Claude Code tab: terminal environment variables on top, the persistent settings.json below (key redacted)

The dialog offers two equivalent routes — pick one:

Route 1: environment variables (current terminal session; append to ~/.bashrc / ~/.zshrc to persist):

export ANTHROPIC_BASE_URL="https://tokens.byteseek.ai"
export ANTHROPIC_AUTH_TOKEN="sk-your-key"
export CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1
export CLAUDE_CODE_ATTRIBUTION_HEADER=0

Route 2: user-level persistent config ~/.claude/settings.json (write once, applies globally; this file contains your key — never commit it to a repository):

{
  "$schema": "https://json.schemastore.org/claude-code-settings.json",
  "env": {
    "ANTHROPIC_BASE_URL": "https://tokens.byteseek.ai",
    "ANTHROPIC_AUTH_TOKEN": "sk-your-key",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1",
    "CLAUDE_CODE_ATTRIBUTION_HEADER": "0"
  }
}

Two notes:

The Base URL has no /v1 — the Anthropic format's paths are appended by the client itself;
The two CLAUDE_CODE_* variables turn off non-essential traffic and the attribution header, trimming irrelevant requests.

If you took the environment-variable route, reload and start:

source ~/.bashrc
claude

What you should see

After starting claude, the welcome banner's API Base URL line shows https://tokens.byteseek.ai (the variables took effect);
A test message gets a normal reply;
/status shows the current model and connection state with no 401 / 403.

Verify

Send any message inside Claude Code — a normal reply means you are connected. To confirm billing attribution, look for the request on the usage page.

Choosing models

Switch models inside Claude Code with /model; availability depends on your key's group — full list in the model plaza. With a composite key, remember the prefix on model IDs.

Common issues

Symptom	Cause and fix
401	Wrong or dead key; confirm `ANTHROPIC_AUTH_TOKEN` is exported without stray spaces
403	Model not in group, group restricted to other clients, or wrong format; recheck the group notes in the model plaza
Variables not applying	No `source` after editing, or overridden elsewhere; check with `echo $ANTHROPIC_BASE_URL`
Slow responses	Slow first tokens are normal for deep-reasoning models; for persistent anomalies see Troubleshooting
