# tokenmeter - AI Usage & Cost Tracking for OpenClaw Track your AI token usage and costs across all providers — locally, privately. ## Slash Command Examples - `/tokenmeter` — show today's dashboard - `/tokenmeter how much did we spend this week?` — weekly cost report - `/tokenmeter costs breakdown by model` — model split analysis - `/tokenmeter import latest sessions` — pull in new usage data - `/tokenmeter compare max plan savings` — show API vs subscription savings ## Overview **tokenmeter** is a CLI tool that tracks LLM API usage and calculates real-time cost estimates. For OpenClaw users on the Claude Max plan, it helps: 1. **Prove Max plan value** - Show what you *would* have paid on API billing 2. **Monitor usage patterns** - Understand which models you use most 3. **Catch overages early** - Know if you're using expensive models too much 4. **Unified tracking** - Track usage across multiple OpenClaw instances All data stays local (SQLite at `~/.tokenmeter/usage.db`). No telemetry, no cloud sync. --- ## Installation **The bot handles everything automatically.** When first needed, the bot will: ```bash # 1. Clone repo if it doesn't exist if [ ! -d ~/clawd/tokenmeter ]; then cd ~/clawd git clone https://github.com/jugaad-lab/tokenmeter.git fi # 2. Setup Python venv if it doesn't exist cd ~/clawd/tokenmeter if [ ! -d ".venv" ]; then python3 -m venv .venv source .venv/bin/activate pip install -e . fi # 3. Activate and use source .venv/bin/activate tokenmeter import --auto ``` **After first setup:** Bot just activates venv and runs commands. **No admin action needed** - the bot clones, installs, and configures automatically when you first ask it to check usage or costs. --- ## How the Bot Uses This Tool ### When You Ask: "How much did I spend this week?" **Step 1: Bot reads this SKILL.md** - Skill matching triggers on keywords: "spend", "cost", "usage", "tokens" - Bot loads this entire file into context **Step 2: Bot checks if tokenmeter exists** ```bash if [ ! -d ~/clawd/tokenmeter ]; then cd ~/clawd git clone https://github.com/jugaad-lab/tokenmeter.git cd tokenmeter python3 -m venv .venv source .venv/bin/activate pip install -e . fi ``` **Step 3: Bot imports latest usage** ```bash cd ~/clawd/tokenmeter source .venv/bin/activate tokenmeter import --auto ``` This reads all OpenClaw session files and logs them to the database. **Step 4: Bot runs the appropriate command** ```bash tokenmeter costs --period week ``` **Step 5: Bot parses the output** ``` Model Cost % of Total ──────────────────────────────────────────── anthropic/claude-opus-4 $741.95 65.0% anthropic/claude-sonnet-4 $400.26 35.0% ──────────────────────────────────────────── Total $1,142.22 ``` **Step 6: Bot responds to you in plain English** > "You spent $1,142 this week (API-equivalent). Opus cost $742 (65%), Sonnet cost $400 (35%). Your Max plan ($100/month = ~$25/week) saved you $1,117 this week." --- ## Bot Command Reference **Standard pattern:** ```bash cd ~/clawd/tokenmeter && source .venv/bin/activate && tokenmeter [command] ``` **Common commands the bot will use:** ```bash # Import latest usage tokenmeter import --auto # Quick overview tokenmeter dashboard # Weekly breakdown tokenmeter costs --period week # Monthly summary tokenmeter summary --period month ``` --- ## Usage ### Quick Commands ```bash # Discover session sources (OpenClaw, Claude Code, etc.) tokenmeter scan # Import all discovered sessions tokenmeter import --auto # Preview import without writing tokenmeter import --auto --dry-run # Show today's usage tokenmeter dashboard # Weekly summary tokenmeter summary --period week # Cost breakdown by model tokenmeter costs --period month # List all supported models + pricing tokenmeter models # View recent history tokenmeter history --limit 20 ``` --- ## Integration with OpenClaw ### Automatic Import (Recommended) OpenClaw writes token usage to session JSONL files at: ``` ~/.clawdbot/agents/*/sessions/*.jsonl ``` **Step 1: Discover session sources** ```bash cd ~/clawd/tokenmeter source .venv/bin/activate tokenmeter scan ``` This shows all discovered session directories: - `.clawdbot/agents/main/sessions/` (OpenClaw) - `.claude/projects/*/sessions/` (Claude Code) - Any other compatible session formats **Step 2: Import all at once** ```bash tokenmeter import --auto ``` This will: - Parse all discovered session files - Extract token usage from each LLM call - Log to tokenmeter with API-equivalent costs - Skip already-imported entries (idempotent) - Show total records and cost **Options:** ```bash tokenmeter import --auto --dry-run # Preview without writing tokenmeter import --path ~/.clawdbot/agents/main/sessions/ # Import specific directory ``` **Recommended:** Run `tokenmeter import --auto` daily via cron or manually after heavy usage. ### Manual Logging (Fallback) If you need to log usage manually: ```bash tokenmeter log \ --provider anthropic \ --model claude-sonnet-4 \ --input 1500 \ --output 500 \ --app openclaw ``` Options: - `--provider` / `-p`: anthropic, openai, google, azure - `--model` / `-m`: Model name (see `tokenmeter models`) - `--input` / `-i`: Input tokens - `--output` / `-o`: Output tokens - `--app` / `-a`: Application name (e.g., "openclaw") --- ## Understanding the Data ### Model Pricing (as of Feb 2026) | Token Type | claude-sonnet-4 | claude-opus-4 | claude-3.5-haiku | |------------|----------------|---------------|------------------| | **Input** | $3.00/1M | $15.00/1M | $0.80/1M | | **Output** | $15.00/1M | $75.00/1M | $4.00/1M | | **Cache Write** | $3.75/1M | $18.75/1M | $1.00/1M | | **Cache Read** | $0.30/1M | $1.50/1M | $0.08/1M | ### Understanding Cache Tokens **What are cache tokens?** OpenClaw (and Claude) use **prompt caching** to store parts of your conversation in memory. This means you don't send the same context repeatedly. **Two types of cache tokens:** 1. **Cache WRITE tokens** - Tokens sent ONCE and stored in cache - Example: Your entire codebase, documentation, system prompts - Slightly more expensive than regular input (~25% markup) - Only paid once, then reused for free (almost) 2. **Cache READ tokens** - Tokens reused from cache - You're NOT sending these again - Claude reads them from memory - **90% cheaper** than regular input tokens - This is where massive savings come from **Real example from our usage:** ``` This Month: Regular Input: 119.5K tokens ($0.36) Regular Output: 3.8M tokens ($57.00) Cache Write: 157.2M tokens ($589.50 - paid once) Cache Read: 1,024.3M tokens ($307.29 - 90% discount!) Total: $954.15 ``` Without caching, we'd send ~1.2 BILLION tokens as regular input ($3,600+). With caching: We only pay $307 for those cache reads. **Savings: $3,293** from caching alone this month! 🎉 ### Reading the Dashboard ``` ╭─────────────────── tokenmeter ───────────────────╮ │ TODAY $122.42 (396.9K tokens) │ │ WEEK $1142.22 (3.4M tokens) │ ╰──────────────────────────────────────────────────╯ Provider Input Output Cache R Cache W Total Cost ─────────────────────────────────────────────────────────── Anthropic 12.2K 384.7K 116.4M 13.1M 396.9K $122.42 ``` **Reading the columns:** - **Input**: Fresh tokens sent to Claude - **Output**: Tokens Claude generated - **Cache R**: Tokens reused from cache (READ) - **Cache W**: Tokens written to cache (WRITE) - **Total**: Input + Output (regular tokens only) - **Cost**: API-equivalent cost **Why Cache R is so large:** Every time you continue a conversation, Claude reads your entire context from cache instead of you sending it fresh. Over many turns, this adds up to billions of tokens reused. **Cost breakdown:** - Regular tokens: Expensive ($3-15 per 1M) - Cache Write: Slightly more expensive (~25% markup) - Cache Read: **90% cheaper** ($0.30-1.50 per 1M) This is why the cost stays low despite huge cache numbers. ### Comparing to Claude Max Plan **Your Max plan:** $100/month flat rate **If tokenmeter shows $800 this month:** - API-equivalent cost: $800 - Max plan cost: $100 - **Savings: $700** ✅ **If tokenmeter shows $90 this month:** - API-equivalent cost: $90 - Max plan cost: $100 - **Overpaying by $10** (but you get peace of mind!) --- ## Workflows ### Daily Check-In ```bash cd ~/clawd/tokenmeter source .venv/bin/activate # Import latest usage tokenmeter import --auto # Quick overview tokenmeter dashboard ``` ### Weekly Review ```bash tokenmeter summary --period week tokenmeter costs --period week ``` Look for: - Heavy Opus usage (expensive!) - Unusual spikes - High output token counts (code generation, long responses) ### Monthly Billing Comparison At month end: ```bash tokenmeter costs --period month ``` Compare to your Anthropic invoice: - Max plan: $100 flat - API-equivalent (tokenmeter): $XXX - Delta = savings (or loss) --- ## Cron Automation (Optional) Add to your HEARTBEAT.md or run via cron: ```bash # Run daily at 11 PM 0 23 * * * cd ~/clawd/tokenmeter && source .venv/bin/activate && tokenmeter import --auto ``` This keeps tokenmeter in sync without manual effort. --- ## Multi-Bot Tracking If you run multiple OpenClaw instances (e.g., Cheenu + Chhotu): 1. Both bots import to tokenmeter on their respective machines 2. Each uses `--app` flag to distinguish: ```bash tokenmeter log -p anthropic -m claude-sonnet-4 -i 1000 -o 500 --app cheenu tokenmeter log -p anthropic -m claude-sonnet-4 -i 800 -o 400 --app chhotu ``` 3. Nagaconda can aggregate reports from both to see total team usage --- ## Troubleshooting ### "tokenmeter: command not found" Activate the virtual environment: ```bash cd ~/clawd/skills/tokenmeter source .venv/bin/activate ``` ### Empty dashboard after import Check: 1. OpenClaw session files exist: `ls ~/.clawdbot/agents/*/sessions/*.jsonl` 2. Import command ran successfully (no errors) 3. Database has entries: `sqlite3 ~/.tokenmeter/usage.db "SELECT COUNT(*) FROM usage;"` ### Prices seem wrong Pricing is based on API rates as of Feb 2026. If Anthropic changes pricing, update `tokenmeter/pricing.py` or open an issue on GitHub. --- ## Examples ### Example 1: Check today's usage ```bash $ tokenmeter dashboard ╭─────────────────── tokenmeter ───────────────────╮ │ TODAY $4.23 (141,000 tokens) │ │ WEEK $28.90 (963,000 tokens) │ ╰──────────────────────────────────────────────────╯ ``` **Analysis:** $4.23 today, trending toward ~$30/week. Well within Max plan ($100/mo). ### Example 2: Weekly cost breakdown ```bash $ tokenmeter costs --period week Provider Model Input Output Cost % ───────────────────────────────────────────────────────────── Anthropic claude-sonnet-4 450K 180K $4.05 45% Anthropic claude-opus-4 90K 30K $3.60 40% Anthropic claude-3.5-haiku 800K 200K $1.44 15% ───────────────────────────────────────────────────────────── Total 1,340K 410K $9.09 100% ``` **Analysis:** Using Opus for 40% of costs but only ~7% of token volume. Consider using Sonnet more. ### Example 3: Month-end comparison (Real Data - Feb 2026) ```bash $ tokenmeter import --auto Imported 13,713 records Total cost: $1,246.55 $ tokenmeter costs --period month Model Input Output Cost % of Total ───────────────────────────────────────────────────────────────── anthropic/claude-opus-4 47.3K 1.6M $743.35 59.6% anthropic/claude-sonnet-4 70.8K 2.2M $501.75 40.3% ───────────────────────────────────────────────────────────────── Total 118.8K 3.8M $1,246.55 100% $ tokenmeter summary --period month Provider Input Output Total Cost Requests ───────────────────────────────...
