Clawdbot Cost Tracker

Track token usage and estimate API costs across all Clawdbot sessions.

Quick Start

Get Current Usage

bash

# Use sessions_list to get token data
sessions_list --limit 20 --messageLimit 0

Extract totalTokens and model from each session.

Calculate Cost

Model pricing (USD per million tokens):

Model	Input	Output	Avg Ratio
claude-opus-4-5	$15	$75	30/70
claude-sonnet-4	$3	$15	30/70
codex-mini-latest	$1	$5	30/70
gpt-4o	$2.5	$10	30/70
gpt-4o-mini	$0.15	$0.6	30/70

Cost formula (assuming 30% input, 70% output):

code

cost = tokens * (0.3 * input_price + 0.7 * output_price) / 1,000,000

Daily Tracking

Save Usage Snapshot

Store daily snapshots in memory/usage/YYYY-MM-DD.json:

json

{
  "date": "2026-01-29",
  "timestamp": "2026-01-29T08:20:00+08:00",
  "sessions": {
    "session_key": {
      "model": "claude-opus-4-5",
      "totalTokens": 123456,
      "channel": "discord"
    }
  },
  "summary": {
    "totalTokens": 250000,
    "byModel": {
      "claude-opus-4-5": 220000,
      "codex-mini-latest": 30000
    }
  }
}

Calculate Daily Cost

Compare consecutive days to get daily usage:

code

daily_tokens = today.totalTokens - yesterday.totalTokens
daily_cost = estimate_cost(daily_tokens, model)

Scripts

`scripts/snapshot-usage.js`

Creates a usage snapshot from current session data.

bash

node scripts/snapshot-usage.js [output-dir]
# Default output: memory/usage/YYYY-MM-DD.json

`scripts/calculate-cost.js`

Calculates cost for a date range.

bash

node scripts/calculate-cost.js [date]
# Default: today
# Output: JSON with token delta and estimated cost

Integration with Daily Report

Add to HEARTBEAT.md:

•Call sessions_list to get current tokens
•Load previous day's snapshot from memory/usage/
•Calculate delta and estimate cost

•Include in daily report format:

code
