AI Usage

Check AI usage across Anthropic and other providers. Use when: 1. User asks about AI usage, token usage, or quota 2. User says "what's my AI usage" or "how much have I used" 3. User asks about Anthropic/Claude usage or limits 4. User asks about costs or spending on AI 5. Monitoring usage during heartbeats (daily check)

File contents

AI Usage Check

Quick Start

python3 scripts/usage_check.py           # Pretty report with gauges
python3 scripts/usage_check.py --json    # JSON output for scripting

Requirements

Python 3.10+ (no pip dependencies — stdlib only)
Claude Code installed and authenticated (claude CLI in PATH) — for Anthropic quota
OpenClaw installed — for session log token/cost stats

What It Shows

Anthropic (real quota from OAuth API):

Weekly utilization % with reset countdown
5-hour rolling window %
Model-specific weekly (Sonnet, Opus) when available
Extra usage spend vs monthly limit

Other Providers (from OpenClaw session logs):

Token counts and call counts per model
Auto-detects any provider OpenClaw routes through (Ollama, OpenAI, etc.)

OpenClaw Anthropic breakdown:

Per-model token counts and equivalent API cost

How It Works

Anthropic quota: GET https://api.anthropic.com/api/oauth/usage using Claude Code's OAuth token from ~/.claude/.credentials.json (requires user:profile scope)
Token auto-refresh: If the token is expired, the script automatically refreshes it by invoking claude --print -p "ok" (Claude Code refreshes its own OAuth token on any invocation), then re-reads the updated credentials file. If Claude Code isn't installed, Anthropic quota is skipped gracefully.
Session stats: Parses ~/.openclaw/agents/main/sessions/*.jsonl for per-provider/model token and cost data

Environment Variables

Variable	Default	Description
`OPENCLAW_SESSIONS_DIR`	`~/.openclaw/agents/main/sessions`	OpenClaw session log directory
`CLAUDE_CREDENTIALS_PATH`	`~/.claude/.credentials.json`	Claude Code credentials file

Tips

Run via Haiku or a lightweight model for heartbeat/background checks — the script just needs to execute, no reasoning required
Use --json for programmatic consumption (cron jobs, dashboards, alerts)
Works with any Anthropic subscription tier (Pro, Max, Team, etc.)
