Why cwatch?

	cwatch	claude-monitor
Dependencies	zero (stdlib only)	Rich, Pydantic, pytz…
Data source	live OAuth API	local JSONL files
Install	pip install cwatch	requires ccusage (npm) + pip
Python	3.9+	3.9+

cwatch reads the same internal API endpoint that Claude Code itself uses — numbers are exact and real-time, no token-counting heuristics.

Install

pip install cwatch
# or isolated (recommended)
pipx install cwatch
uv tool install cwatch

Requires: Python 3.9+ and having run claude login at least once.

Usage

cwatch                        # live dashboard, refresh every 60s
cwatch --interval 30          # faster refresh
cwatch --once                 # one compact line, then exit
cwatch --json                 # raw API JSON dump
cwatch --token sk-ant-oat01-… # explicit token
CLAUDE_TOKEN=sk-… cwatch      # token via env var

tmux statusline

set -g status-right "#(cwatch --once)  %H:%M"
set -g status-interval 60

How it works

Calls GET https://api.anthropic.com/api/oauth/usage with your Claude Code OAuth token (read from macOS Keychain, ~/.claude/.credentials.json, or CLAUDE_TOKEN env var).

Python API

from cwatch.credentials import get_token
from cwatch.api import fetch

data = fetch(get_token())
print(f"5h session: {data.five_hour.pct}%  resets in {data.five_hour.time_until_reset}")
