```typescript
// POST /api/invoices/analyze
// Request: multipart/form-data with invoice file
// Response: InvoiceAnalysisResult
fetch('/api/invoices/analyze', {
  method: 'POST',
  body: formData // containing invoice file
});

// POST /api/threats/report
// Request: { invoiceId, vendor, fraudScore, reason, amount }
// Response: { success: boolean, threatId: string }
fetch('/api/threats/report', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify(threatData)
});

// GET /api/threats/analytics
// Response: ThreatAnalytics
fetch('/api/threats/analytics');

// GET /api/wallet/balance
// Response: WalletBalance
fetch('/api/wallet/balance');

// GET /api/transactions
// Response: Transaction[]
fetch('/api/transactions');

### Mock API Layer for Invoice Analysis and Threat Reporting

Source: https://github.com/steve-dusty/shieldnet/blob/main/SHIELDNET_SUMMARY.md

Provides mock implementations for key API functions like analyzing invoices and reporting threats. It includes TypeScript interfaces for data structures and simulates API delays. This layer is intended for frontend development and testing before backend integration.

```typescript
import {
  InvoiceAnalysisResult,
  ThreatSummary,
  Transaction,
  WalletBalance,
} from './types';

const simulateApiDelay = (min = 500, max = 1500) =>
  new Promise((resolve) => setTimeout(resolve, Math.random() * (max - min) + min));

export const analyzeInvoice = async (invoiceData: any): Promise<InvoiceAnalysisResult> => {
  await simulateApiDelay();
  const fraudScore = Math.random() * 100;
  let status: 'Approved' | 'Hold' | 'Blocked';
  if (fraudScore >= 85) {
    status = 'Blocked';
  } else if (fraudScore >= 70) {
    status = 'Hold';
  } else {
    status = 'Approved';
  }
  return {
    status,
    confidenceScore: Math.random() * 100,
    fraudScore,
    localChecks: {
      poMatch: Math.random() > 0.2,
      hoursVerification: Math.random() > 0.1,
    },
    networkSignals: Math.random() > 0.5 ? ['flagged_by_others'] : [],
  };
};

export const getThreatAnalytics = async (): Promise<ThreatSummary> => {
  await simulateApiDelay();
  const threats = Array.from({ length: 5 }, (_, i) => ({
    id: `T${Date.now()}${i}`,
    vendor: `Vendor ${i + 1}`,
    fraudScore: Math.random() * 100,
    reason: 'Suspicious patterns detected',
    firstSeen: new Date(Date.now() - Math.random() * 100000000).toISOString(),
    timesSeen: Math.floor(Math.random() * 10) + 1,
    amountBlocked: `$${(Math.random() * 5000).toFixed(2)}`,
  }));
  return {
    totalThreatsBlocked: Math.floor(Math.random() * 1000),
    totalFraudAvoided: `$${(Math.random() * 1000000).toFixed(2)}`,
    uniqueThreats: Math.floor(Math.random() * 50) + 5,
    rewardsEarned: `$${(Math.random() * 10000).toFixed(2)}`,
    threats: threats,
  };
};

export const getTransactions = async (): Promise<Transaction[]> => {
  await simulateApiDelay();
  return Array.from({ length: 6 }, (_, i) => ({
    id: `TXN${Date.now()}${i}`,

    date: new Date(Date.now() - Math.random() * 10000000).toISOString(),
    status: ['Success', 'Blocked', 'Pending'][Math.floor(Math.random() * 3)] as any,
    reason: 'Automated verification',
    invoiceId: `INV${Date.now()}${i}`,
  }));
};

export const getWalletBalance = async (): Promise<WalletBalance> => {
  await simulateApiDelay();
  return {
    usdcBalance: Math.random() * 100000,
    monthlySummary: {
      autoPaid: `$${(Math.random() * 50000).toFixed(2)}`,
      blocked: `$${(Math.random() * 5000).toFixed(2)}`,
    },
  };
};

export const reportThreat = async (threatData: any) => {
  await simulateApiDelay();
  console.log('Threat reported:', threatData);
  // TODO: Implement actual threat reporting logic
};

// Define types in a separate file (e.g., types.ts)
// export interface InvoiceAnalysisResult { ... }

### Monitor Treasury Wallet Balance (TypeScript)

Source: https://context7.com/steve-dusty/shieldnet/llms.txt

Fetches the current USDC wallet balance and monthly summaries using `getWalletBalance`. It logs the current balance, auto-paid amounts, and blocked amounts for the month. This function depends on the '@/services/mockApi' module.

```typescript
import { getWalletBalance, WalletBalance } from '@/services/mockApi';

// Get current wallet balance and monthly summaries
const loadWalletData = async () => {
  try {
    const balance: WalletBalance = await getWalletBalance();

    console.log('Current Balance:', balance.balance.toLocaleString(), balance.currency);
    // Output: Current Balance: 48,200 USDC

    console.log('Auto-Paid This Month:', balance.autoPaidThisMonth);
    // Output: Auto-Paid This Month: 34500

    console.log('Blocked This Month:', balance.blockedThisMonth);
    // Output: Blocked This Month: 23400

    return balance;
  } catch (error) {
    console.error('Failed to fetch wallet balance:', error);
    throw error;
  }
};

```

        console.error(err);
      } finally {
        setIsLoading(false);
      }
    };
    fetchAnalytics();
  }, []);

  const getFraudScoreBadgeColor = (score: number) => {

### Analyze Invoices for Fraud Risk with TypeScript

Source: https://context7.com/steve-dusty/shieldnet/llms.txt

Analyzes uploaded invoices for fraud risk using multi-agent verification. It takes a File object as input and returns an InvoiceAnalysisResult, including status, confidence, fraud score, and detailed local and network checks. This function relies on the 'analyzeInvoice' service from '@/services/mockApi'.

```typescript
import { analyzeInvoice, InvoiceAnalysisResult } from '@/services/mockApi';

// Analyze an invoice file
const handleInvoiceUpload = async (file: File) => {
  try {
    const result: InvoiceAnalysisResult = await analyzeInvoice(file);

    // Result includes status, confidence, fraud score, and detailed checks
    console.log('Status:', result.status); // 'approved' | 'hold' | 'blocked'
    console.log('Confidence:', result.confidence); // 0-100
    console.log('Fraud Score:', result.fraudScore); // 0-100

    // Local security checks (PO match, hours verification, vendor trust)
    result.localChecks.forEach(check => {
      console.log(`${check.name}: ${check.status} - ${check.detail}`);
    });

    // Network signals (flagged by others, seen in network)
    result.networkSignals.forEach(signal => {
      console.log(`${signal.type}: ${signal.description}`);
    });

    // Example approved invoice response:
    // {
    //   invoiceId: 'INV-2024-001',
    //   status: 'approved',
    //   confidence: 96,
    //   fraudScore: 8,
    //   vendor: 'CloudHosting Inc.',
    //   amount: 2450.00,
    //   currency: 'USDC',
    //   localChecks: [
    //     { name: 'PO Match', status: 'pass', detail: 'Matches PO-7781' },
    //     { name: 'Hours Verification', status: 'pass', detail: 'Logged hours: 82h, Invoice: 80h' }
    //   ],
    //   networkSignals: [
    //     { type: 'clean', description: 'No similar scams seen in ShieldNet' }
    //   ],
    //   explanation: 'Invoice matches PO-7781 and logged hours; no similar scams seen in ShieldNet.'
    // }

    return result;
  } catch (error) {
    console.error('Analysis failed:', error);
    throw error;
  }
};

### Fetch Threat Analytics Data (TypeScript)

Source: https://context7.com/steve-dusty/shieldnet/llms.txt

Retrieves network-wide threat intelligence and reward data using the `getThreatAnalytics` function. It logs total blocked amounts, invoices stopped, unique threats, earned rewards, and details for individual threat records. This function requires the '@/services/mockApi' module.

```typescript
import { getThreatAnalytics, ThreatAnalytics } from '@/services/mockApi';

// Fetch comprehensive threat analytics
const loadThreatData = async () => {
  try {
    const analytics: ThreatAnalytics = await getThreatAnalytics();

    // Network-wide statistics
    console.log('Total Blocked:', analytics.totalBlockedAmount); // $1,247,500
    console.log('Invoices Stopped:', analytics.totalBlockedInvoices); // 2,847
    console.log('Unique Threats:', analytics.totalThreatsDetected); // 156
    console.log('Rewards Earned:', analytics.rewardsEarned); // $3,450

    // Individual threat records with pattern details
    analytics.threats.forEach(threat => {
      console.log(`Threat: ${threat.vendor}`);
      console.log(`  Risk Score: ${threat.fraudScore}/100`);
      console.log(`  First Seen: ${threat.firstSeen}`);
      console.log(`  Times Seen: ${threat.timesSeen}x across network`);
      console.log(`  Amount Blocked: $${threat.amountBlocked.toLocaleString()}`);
      console.log(`  Reason: ${threat.reason}`);
      if (threat.templateHash) {
        console.log(`  Template Hash: ${threat.templateHash}`);
      }
    });

    return analytics;
  } catch (error) {
    console.error('Failed to fetch analytics:', error);
    throw error;
  }
};

```

### Retrieve Transaction History (TypeScript)

Source: https://context7.com/steve-dusty/shieldnet/llms.txt

Fetches recent payment transaction records, including status and details, using the `getTransactions` function. It iterates through transactions, logging vendor, amount, currency, status, date, invoice ID, and reason. Requires the '@/services/mockApi' module.

```typescript
import { getTransactions, Transaction } from '@/services/mockApi';

// Fetch recent transaction history
const loadTransactions = async () => {
  try {
    const transactions: Transaction[] = await getTransactions();

    transactions.forEach(tx => {
      console.log(`${tx.vendor}: $${tx.amount} ${tx.currency}`);
      console.log(`  Status: ${tx.status}`); // 'paid' | 'held' | 'blocked'
      console.log(`  Date: ${tx.date}`);
      console.log(`  Invoice: ${tx.invoiceId}`);
      console.log(`  Reason: ${tx.reason}`);
    });

    return transactions;
  } catch (error) {
    console.error('Failed to fetch transactions:', error);
    throw error;
  }
};

### Report Blocked Threats to ShieldNet with TypeScript

Source: https://context7.com/steve-dusty/shieldnet/llms.txt

Reports blocked invoices to the ShieldNet network for shared intelligence. This function takes an InvoiceAnalysisResult object and, if the status is 'blocked', calls the 'reportThreat' service to submit threat details. It returns a response containing a threat ID upon successful reporting.

```typescript
import { reportThreat } from '@/services/mockApi';

// Automatically report blocked invoices to the network
const handleBlockedInvoice = async (analysisResult: InvoiceAnalysisResult) => {
  if (analysisResult.status === 'blocked') {
    try {
      const response = await reportThreat({
        invoiceId: analysisResult.invoiceId,
        vendor: analysisResult.vendor,
        fraudScore: analysisResult.fraudScore,
        reason: analysisResult.explanation,
        amount: analysisResult.amount
      });

      console.log('Threat reported:', response.threatId);
      // Example response: { success: true, threatId: 'THR-1699564321000' }

      // This threat is now shared with the network
      // When others query similar patterns, you earn rewards
    } catch (error) {
      console.error('Failed to report threat:', error);
    }
  }
};
```
