Overview

Cost Tracking provides comprehensive visibility into all expenses associated with your AI agents, from API calls to compute resources. Make informed decisions about resource allocation and optimize your operational costs.

​
What Gets Tracked

​
1. API Costs

Monitor costs from external service providers:

Model API Costs

OpenAI, Anthropic, Google, and other LLM providers

Tool API Costs

Third-party tools and services your agents use

Infrastructure Costs

Cloud computing and hosting expenses

Data Transfer Costs

Network and bandwidth usage charges

​
2. Cost Attribution

Understand where your money goes: 
{
  session_id: "session_abc123",
  total_cost: 0.145,
  breakdown: {
    model_costs: {
      gpt_4: 0.089,
      claude_3: 0.023
    },
    tool_costs: {
      search_api: 0.015,
      email_service: 0.008,
      database_query: 0.010
    },
    infrastructure: 0.000
  },
  cost_per_token: 0.00002,
  tokens_used: 7250
}

​
3. Cost Granularity

Track costs at multiple levels:
  • Per Tool Call
  • Per Session
  • Per User
const toolCallCost = {
  call_id: "call_def456",
  tool_name: "search_database",
  cost: 0.012,
  tokens: 600,
  duration: 234,
  cost_per_ms: 0.000051
};

​
Real-Time Cost Monitoring

​
1. Live Cost Dashboard

Monitor spending as it happens:
Real-time view of your spending velocity:
  • Cost per hour - Current hourly spending rate
  • Daily projection - Estimated daily costs
  • Monthly forecast - Projected monthly expenses
  • Budget burn rate - How quickly you’re using your budget
Get notified when spending exceeds thresholds:
  • Budget alerts - When approaching budget limits
  • Spike alerts - Sudden increases in spending
  • Anomaly alerts - Unusual cost patterns
  • Threshold alerts - Custom spending thresholds
Visualize where your money goes:
  • By service - Costs per API provider
  • By tool - Costs per tool type
  • By user - Costs per user or team
  • By time - Costs over time periods

​
2. Budget Management

Set and track spending limits: 
const budgetConfig = {
  monthly_limit: 1000.00,
  alerts: [
    { threshold: 0.50, action: "email" },
    { threshold: 0.80, action: "slack" },
    { threshold: 0.95, action: "disable_non_essential" }
  ],
  auto_actions: {
    hard_limit: 1000.00,
    action: "suspend_all"
  }
};

    cost_per_token: 0.00003,
    success_rate: 0.95,
    cost_per_success: 0.032
  },
  claude_3: {
    cost_per_token: 0.000015,
    success_rate: 0.92,
    cost_per_success: 0.016
  },
  recommendation: "Use Claude 3 for cost optimization"
};

​
3. Cost Forecasting

Predict future costs based on usage patterns:
Predict future usage and costs:
  • Seasonal patterns - Account for seasonal variations
  • Growth trends - Factor in user growth
  • Feature impact - Estimate impact of new features
  • Confidence intervals - Provide prediction ranges
Model different cost scenarios:
  • Best case - Optimal cost scenarios
  • Worst case - Maximum cost scenarios
  • Most likely - Realistic cost projections
  • What-if analysis - Impact of different decisions

​
Advanced Cost Features

​
1. Cost Attribution Models

Different ways to allocate costs: 
// Allocate costs to users
const userAttribution = {
  method: "direct_usage",
  user_costs: {
    "user_123": 45.67,
    "user_456": 23.89,
    "user_789": 67.23
  },
  shared_costs: {
    infrastructure: 12.34,
    overhead: 8.90
  }
};

​
2. Cost Allocation Strategies

  • Direct Allocation
  • Shared Cost Allocation
// Direct cost allocation
const directAllocation = {
  principle: "costs_follow_usage",
  example: {
    user_a: {
      api_calls: 100,
      cost: 12.50,
      cost_per_call: 0.125
    },
    user_b: {
      api_calls: 50,
      cost: 6.25,
      cost_per_call: 0.125
    }
  }
};
