Lindy Cost Tuning

Overview

Optimize Lindy AI costs while maintaining service quality.

Prerequisites

• Access to Lindy billing dashboard
• Usage data available
• Understanding of pricing tiers

Instructions

Step 1: Analyze Current Usage

import { Lindy } from '@lindy-ai/sdk';

async function analyzeUsage() {
  const lindy = new Lindy({ apiKey: process.env.LINDY_API_KEY });

  const usage = await lindy.usage.monthly({
    startDate: '2025-01-01',
    endDate: '2025-01-31',
  });

  const analysis = {
    totalRuns: usage.agentRuns.total,
    totalCost: usage.billing.total,
    costPerRun: usage.billing.total / usage.agentRuns.total,
    topAgents: usage.byAgent
      .sort((a: any, b: any) => b.cost - a.cost)
      .slice(0, 5),
    peakHours: usage.byHour
      .sort((a: any, b: any) => b.runs - a.runs)
      .slice(0, 5),
  };

  console.log('Usage Analysis:', analysis);
  return analysis;
}

Step 2: Implement Usage Budgets

interface Budget {
  monthly: number;
  daily: number;
  perAgent: number;
}

const budget: Budget = {
  monthly: 500, // $500/month
  daily: 20,    // $20/day
  perAgent: 50, // $50/agent/month
};

async function checkBudget(): Promise<boolean> {
  const lindy = new Lindy({ apiKey: process.env.LINDY_API_KEY });

  const usage = await lindy.usage.current();

  if (usage.billing.monthly >= budget.monthly) {
    console.error('Monthly budget exceeded!');
    await sendAlert('Budget exceeded', { usage, budget });
    return false;
  }

  if (usage.billing.today >= budget.daily) {
    console.warn('Daily budget exceeded');
    return false;
  }

  return true;
}

Step 3: Optimize Agent Costs

// Cost-optimized agent configuration
const optimizedAgent = {
  name: 'Cost-Efficient Agent',
  instructions: 'Be brief. Answer in 1-2 sentences.',
  config: {
    model: 'gpt-3.5-turbo', // Cheaper model
    maxTokens: 100,         // Limit output
    temperature: 0.3,       // Less creative = fewer tokens
  },
};

// Route simple queries to cheaper agents
async function routeQuery(input: string) {
  const isSimple = input.length < 100 && !input.includes('analyze');

  const agentId = isSimple
    ? 'agt_cheap_simple'
    : 'agt_expensive_complex';

  return lindy.agents.run(agentId, { input });
}

Step 4: Implement Caching to Reduce Calls

import NodeCache from 'node-cache';

const cache = new NodeCache({ stdTTL: 3600 }); // 1 hour cache

async function cachedRun(agentId: string, input: string) {
  const cacheKey = `${agentId}:${input}`;

  // Check cache first (free!)
  const cached = cache.get(cacheKey);
  if (cached) {
    console.log('Cache hit - $0');
    return cached;
  }

  // Only call API if cache miss
  const result = await lindy.agents.run(agentId, { input });
  cache.set(cacheKey, result);

  console.log('Cache miss - API call made');
  return result;
}

Step 5: Set Up Cost Alerts

async function setupCostAlerts() {
  const lindy = new Lindy({ apiKey: process.env.LINDY_API_KEY });

  // Alert at 80% of budget
  await lindy.billing.alerts.create({
    threshold: 400, // $400 of $500 budget
    type: 'monthly',
    channels: ['email', 'slack'],
    message: 'Approaching monthly budget limit',
  });

  // Daily anomaly detection
  await lindy.billing.alerts.create({
    threshold: 50, // 50% above average
    type: 'anomaly',
    channels: ['slack'],
    message: 'Unusual spending detected',
  });
}

Cost Optimization Checklist

[ ] Usage analysis completed
[ ] Budget limits defined
[ ] Cost alerts configured
[ ] Caching implemented
[ ] Cheaper models for simple tasks
[ ] Max tokens configured
[ ] Unused agents identified and disabled
[ ] Peak usage patterns analyzed

Output

• Usage analysis report
• Budget enforcement
• Cost-optimized agents
• Caching for reduced API calls
• Alert system

Error Handling

Issue	Cause	Solution
Budget exceeded	High usage	Throttle or pause
Cost spike	Anomaly	Investigate and alert
Cache ineffective	Low hit rate	Tune TTL

Examples

Monthly Cost Report

async function generateCostReport() {
  const usage = await analyzeUsage();

  const report = `
# Lindy Cost Report - ${new Date().toISOString().slice(0, 7)}

## Summary
- Total Runs: ${usage.totalRuns}
- Total Cost: $${usage.totalCost.toFixed(2)}
- Cost per Run: $${usage.costPerRun.toFixed(4)}

## Top Agents by Cost
${usage.topAgents.map((a: any) => `- ${a.name}: $${a.cost.toFixed(2)}`).join('\n')}

## Recommendations
${usage.costPerRun > 0.05 ? '- Consider cheaper models for simple tasks' : ''}
${usage.cacheHitRate < 0.3 ? '- Improve caching strategy' : ''}
  `;

  return report;
}
