Credit System Integration - Complete

✅ Integration Completed

The credit system has been fully integrated into the existing GovIntel application. Credits are now consumed for the following actions:

---

🎯 Integrated Features

1. Connection Requests (connection_request - 15 credits)

Location: apps/backend/src/govintel/services/connection-management.service.ts

What happens:

• ✅ Before creating connection: Checks if startup has sufficient credits
• ✅ After creating connection: Consumes 15 credits from startup's balance
• ✅ If insufficient credits: Throws error with clear message about available vs required credits
• ✅ Transaction safety: If credit consumption fails, connection is rolled back

Code changes:

• Added CreditService injection to constructor
• Added credit check before connection creation (line ~194)
• Added credit consumption after successful connection (line ~252)
• Includes rollback logic if credit consumption fails

Error message example:

Insufficient credits. Required: 15, Available: 5. Please contact support to add more credits.

---

2. Warm Introduction Requests (warm_intro_request - 20 credits)

Location: apps/backend/src/govintel/services/connection-management.service.ts

What happens:

• ✅ Before creating warm intro: Checks if startup has sufficient credits
• ✅ After creating warm intro request: Consumes 20 credits
• ✅ If insufficient credits: Throws error before creating request
• ✅ Transaction safety: If credit consumption fails, warm intro request is rolled back

Code changes:

• Added credit check before warm intro creation (line ~516)
• Added credit consumption after successful warm intro (line ~549)
• Includes rollback logic if credit consumption fails

---

3. Save Signal / Signal Pool Requests (signal_pool_request - 10 credits)

Location: apps/backend/src/govintel/controllers/govintel.controller.ts

What happens:

• ✅ Before saving signal: Checks if startup has sufficient credits (if startupId provided)
• ✅ After saving signal: Consumes 10 credits (only for new saves, not updates)
• ✅ If insufficient credits: Throws error before saving
• ✅ Transaction safety: If credit consumption fails, saved signal is rolled back

Code changes:

• Added CreditService injection to controller constructor
• Modified saveSignal() endpoint to accept startupId in request body
• Added credit check before saving (line ~2475)
• Added credit consumption after new signal save (line ~2510)
• Only consumes credits on first save, not when updating existing saved signal

Note: This endpoint now supports optional startupId in the request body:

{
  "signalId": "signal-123",
  "signalData": {...},
  "startupId": "startup-456",  // <-- New field for credit tracking
  "userId": "user-789",
  "notes": "Interested in this opportunity",
  "tags": ["high-priority"]
}

---

4. Signal View Details (signal_view_details - 5 credits)

Location: apps/backend/src/govintel/controllers/govintel.controller.ts (line ~374)

What happens:

• ✅ Before viewing signal: Checks if startup has sufficient credits (if startupId provided)
• ✅ After viewing signal: Consumes 5 credits
• ✅ If insufficient credits: Throws error before displaying details
• ✅ Transaction safety: Credits consumed after successful retrieval

Code changes:

• Modified GET /signals/:id endpoint to accept optional startupId query parameter
• Added credit check before retrieving signal details (line ~398)
• Added credit consumption after successful retrieval (line ~446)
• Includes metadata: signalId, governmentName, mqlScore

Usage:

GET /govintel/signals/{signalId}?startupId={startupId}

---

5. Priority Matching (priority_matching - 25 credits)

Location: apps/backend/src/govintel/controllers/govintel.controller.ts (line ~2976)

What happens:

• ✅ Before running AI matching: Checks if startup has sufficient credits
• ✅ After successful matching: Consumes 25 credits
• ✅ If insufficient credits: Throws error before running expensive AI operation
• ✅ Transaction safety: Credits consumed after matches are generated

Code changes:

• Modified POST /signals/:signalId/matches endpoint to accept startupId in body
• Added credit check before running RAG matching (line ~3001)
• Added credit consumption after successful matching (line ~3078)
• Includes metadata: totalMatches, highConfidenceMatches, governmentName

Usage:

POST /govintel/signals/{signalId}/matches
{
  "startupId": "startup-456",
  "minSimilarityThreshold": 0.7,
  "maxMatchesPerSignal": 10,
  "includeExplanations": true
}

---

📋 Module Configuration

Updated: apps/backend/src/govintel/govintel.module.ts

• ✅ Added CreditService import
• ✅ Added CreditService to providers array
• ✅ CreditService is now available to all GovIntel services

---

🎨 Credit Cost Summary

Action	Credit Cost	Description
Signal Pool Request	10 credits	Saving a signal for review and potential connection
Connection Request	15 credits	Requesting introduction to government contact
Warm Intro Request	20 credits	Requesting facilitated warm introduction
Signal View Details	5 credits	Viewing detailed information about a signal
Priority Matching	25 credits	AI-powered RAG matching for optimal startup matches

🔄 How It Works - Flow Diagram

Connection Request Flow:

User initiates connection
    ↓
Check if startup has ≥15 credits
    ↓
├─ YES → Create connection in database
│         ↓
│         Consume 15 credits
│         ↓
│         Log transaction
│         ↓
│         Return success
│
└─ NO → Return error: "Insufficient credits"
         (No connection created, no credits consumed)

Credit Consumption Transaction:

1. Startup Balance: 100 credits
2. Request connection (costs 15)
3. Update: creditsUsed +15, creditsRemaining -15
4. Create transaction record: -15, balance_after: 85
5. Log: "Connection request to [gov name] for signal [id]"
6. New Balance: 85 credits

---

💾 Database Records Created

For each credit consumption, a CreditTransaction record is created with:

• startupId: Which startup used credits
• actionType: What action was performed
• amount: Negative value (e.g., -15 for consumption)
• balanceAfter: Remaining credits after transaction
• description: Human-readable description of the action
• entityId: ID of the related entity (connection, signal, etc.)
• entityType: Type of entity ("connection", "warm_intro_request", "saved_signal")
• metadata: Additional context (signal ID, match score, etc.)
• createdAt: Timestamp of transaction

---

🚦 Error Handling

Insufficient Credits Error:

BadRequestException:
  "Insufficient credits. Required: 15, Available: 5.
   Please contact support to add more credits."

Credit Consumption Failure:

InternalServerErrorException: "Connection created but credit consumption failed: [error details]";
// Note: Connection is automatically rolled back

Unlimited Tier:

// Startups on "unlimited" tier bypass all credit checks
if (startup.creditTier === "unlimited") {
  // No credit deduction, action proceeds normally
}

---

🧪 Testing the Integration

Test Connection Request:

# 1. Check current credits
GET http://localhost:3800/credits/balance
# Response: { creditsRemaining: 100, creditTier: "basic" }

# 2. Create a connection (costs 15 credits)
POST http://localhost:3800/govintel/connections
{
  "signalId": "signal-123",
  "startupId": "startup-456",
  "matchScore": 8.5,
  "matchReasons": ["Strong category match"],
  "priority": "High"
}

# 3. Check credits again
GET http://localhost:3800/credits/balance
# Response: { creditsRemaining: 85, creditTier: "basic" }

# 4. View transaction history
GET http://localhost:3800/credits/history
# Shows: -15 credits, action: "connection_request", timestamp, etc.

Test Insufficient Credits:

# Set credits to low amount (admin only)
POST http://localhost:3800/admin/credits/startups/{id}/deduct
{ "amount": 95, "reason": "Testing low credits" }

# Try to create connection (requires 15, only have 5)
POST http://localhost:3800/govintel/connections
# Response: 400 Bad Request - "Insufficient credits. Required: 15, Available: 5"

🎯 What's NOT Implemented (Future Work)

Frontend Updates Needed:

• Update frontend to pass startupId in save signal requests
