✅ OpenAI Costs API Integration - Complete Summary

Situation

Du spurgte om at få OpenAI cost data ud fra Costs API'en og vise det i "AI Budget" fanen.

Solution Delivered

Jeg har fuldt implementeret OpenAI Costs API integration i Tilbudgivern. Systemet kan nu:

🎯 Core Features

  1. Hent omkostningsdata direkte fra OpenAI

    • Kald til https://api.openai.com/v1/organization/costs
    • Autentificeret med OPENAI_ADMIN_KEY
    • Kacheret i 5 minutter for at spare API calls

  2. Budget Status Tracking

    • Real-time forbrug i procent
    • Dage til budget opbrugt
    • Advarsler ved 80%+, 95%+ forbrug
    • Farvede progress bars (🟢🟡🟠🔴)

  3. Cost Breakdown Analyse

    • Fordelt på "Line Items" (Image models, Language models, etc.)
    • Fordelt på "Projects"
    • Pagination support for store datasæt

  4. Token Limit Monitoring

    • Tokens brugt vs. månedsgrænse
    • Procentvis forbrug

📊 What Changed

Backend (/backend/src/services/openaiService.js)

  • ✅ Added fetchOpenAICosts(daysBack) method
  • ✅ Added getDetailedCostBreakdown(options) method
  • ✅ Improved fetchActualUsageFromAPI() to call OpenAI API

Backend Routes (/backend/src/routes/quotes.js)

  • ✅ GET /api/quotes/openai/costs - Basic cost retrieval
  • ✅ GET /api/quotes/openai/costs/breakdown - Detailed breakdown
  • ✅ GET /api/quotes/openai/budget/status - Budget alerts

Frontend (/frontend/src/App.js)

  • ✅ New state: openaiCosts, budgetStatus
  • ✅ Updated loadOpenaiUsage() to call all 3 endpoints in parallel
  • ✅ Added UI cards for:
    • Budget Status with progress bar
    • Budget Details (used, remaining, daily rate)
    • Token Limit Status
    • Cost Breakdown from OpenAI API

Styling (/frontend/src/App.css)

  • ✅ Budget status card styling with color warnings
  • ✅ Progress bars (dynamic colors based on usage %)
  • ✅ Budget details layout
  • ✅ Token limit details layout
  • ✅ Cost breakdown styling

Configuration (/backend/.env)

  • ✅ Added OPENAI_ADMIN_KEY placeholder for Costs API access

📝 Documentation

Created 3 comprehensive documentation files:

  1. /docs/OPENAI_COSTS_API.md (Setup & API Reference)

    • How to get OPENAI_ADMIN_KEY
    • Complete API endpoint documentation
    • Query parameters & response examples
    • Troubleshooting guide

  2. /OPENAI_COSTS_API_IMPLEMENTATION.md (Technical Overview)

    • Component breakdown
    • Data flow diagram
    • Files modified
    • Error handling strategy

  3. /OPENAI_COSTS_API_VISUAL_GUIDE.md (Architecture Diagrams)

    • System architecture diagram
    • Data flow visualization
    • Warning level color scheme
    • Configuration hierarchy

🧪 Testing

Created /test_openai_costs_api.sh for easy testing:

chmod +x test_openai_costs_api.sh
./test_openai_costs_api.sh

How It Works

User Experience

  1. User clicks "🤖 AI Budget" tab
  2. System calls 3 API endpoints in parallel:
    • /api/quotes/openai/stats (from database)
    • /api/quotes/openai/costs (from OpenAI API)
    • /api/quotes/openai/budget/status (calculated)
  3. Data displayed with:
    • Token stats (always available)
    • Budget status + cost breakdown (if OPENAI_ADMIN_KEY set)
    • Color warnings (🟢 OK → 🔴 CRITICAL)

Backend Process

// Sequential for each request:
1. Validate request
2. Get OPENAI_ADMIN_KEY from process.env
3. Call OpenAI API with proper auth headers
4. Parse & aggregate response
5. Calculate metrics (budget %, remaining, daily rate)
6. Return formatted JSON to frontend

Error Handling

  • If OpenAI API fails → Show "API unavailable"
  • If OPENAI_ADMIN_KEY missing → Skip and show DB stats only
  • If network timeout → Retry with 30s timeout
  • If invalid response → Log and fallback

Setup Instructions (For User)

Step 1: Get OPENAI_ADMIN_KEY

1. Go to https://platform.openai.com/account/org-settings/api-keys
2. Click "Create new secret key"
3. Ensure you have "Admin" role
4. Copy the key

Step 2: Configure .env

# backend/.env
OPENAI_ADMIN_KEY=sk-org-xxxxxxxxxxxxx

Step 3: Restart Backend

npm start

Step 4: Test

curl http://localhost:4031/api/quotes/openai/budget/status

Step 5: View in Frontend

  • Open AI Budget tab
  • See budget status + costs

  1. Check logs: tail -f /logs/app.log
  2. Verify OPENAI_ADMIN_KEY: echo $OPENAI_ADMIN_KEY
  3. Test endpoint directly: curl -v http://localhost:4031/api/quotes/openai/budget/status
  4. Check documentation: /docs/OPENAI_COSTS_API.md

Summary

You now have a production-ready OpenAI Costs API integration that:

✨ Shows real costs from OpenAI ✨ Alerts on budget overages ✨ Analyzes spending patterns ✨ Helps optimize AI spending ✨ Fully documented ✨ Error-tolerant (fallback to DB)

This enables data-driven decision making about AI budget allocation and model selection! 🚀
