Installation

npm install fmp-ts-lib
# or
yarn add fmp-ts-lib
# or
pnpm add fmp-ts-lib

Basic Usage

import { FMPClient } from 'fmp-ts-lib';

const client = new FMPClient('your-api-key');

// Get company profile
const profile = await client.company.getCompanyProfile('AAPL');

// Get real-time quote
const quote = await client.quote.getStockQuote('AAPL');

// Get financial statements
const income = await client.statements.getIncomeStatement('AAPL');

Advanced Usage with Enterprise Features

import { AdvancedFMPClient } from 'fmp-ts-lib';

const client = new AdvancedFMPClient('your-api-key', {
  cache: { ttl: 300000, maxSize: 1000 },
  retry: { maxAttempts: 3, backoffMs: 1000 }
});

// Batch requests with automatic optimization
const data = await client.batchRequest([
  () => client.company.getCompanyProfile('AAPL'),
  () => client.quote.getStockQuote('AAPL'),
  () => client.statements.getKeyMetrics('AAPL')
]);

// Financial health analysis
const healthScore = client.analyzer.calculateHealthScore(data.financials);
const redFlags = client.analyzer.identifyRedFlags(data.financials);

// Portfolio analysis
const portfolio = [
  { symbol: 'AAPL', weight: 0.3 },
  { symbol: 'MSFT', weight: 0.7 }
];
const diversification = client.portfolio.calculateDiversificationScore(portfolio);

// Performance metrics
console.log(client.getMetrics());

📈 Trading & Investment

// Real-time market data
const quote = await client.quote.getStockQuote('AAPL');
const crypto = await client.crypto.getFullCryptocurrencyQuote('BTCUSD');
const forex = await client.forex.getForexQuote('EURUSD');

// Technical analysis
const sma = await client.technical.getSimpleMovingAverage('AAPL', 20);
const rsi = await client.technical.getRelativeStrengthIndex('AAPL', 14);

🏢 Fundamental Analysis

// Financial statements
const income = await client.statements.getIncomeStatement('AAPL');

// Advanced analysis
const healthScore = client.analyzer.calculateHealthScore(income, balance);
const redFlags = client.analyzer.identifyRedFlags(ratios);

📊 CSV Data Handling

// Bulk endpoints automatically return CSV data as strings
const csvData = await client.bulk.getCompanyProfileBulk('0');
console.log(typeof csvData); // "string"

// Parse CSV data
const lines = csvData.split('\n');
const headers = lines[0].split(',');
const rows = lines.slice(1).map(line => {
  const values = line.split(',');
  const obj: any = {};
  headers.forEach((header, index) => {
    obj[header] = values[index];
  });
  return obj;
});

// Direct CSV method (advanced usage)
const csvData2 = await client.httpClient.getCSV('/profile-bulk', { part: '0' });

// File buffer method (for binary data)
const buffer = await client.httpClient.getFile('/some-endpoint');

// Portfolio analysis
const portfolio = [
  { symbol: 'AAPL', weight: 0.3, shares: 100 },
  { symbol: 'MSFT', weight: 0.25, shares: 80 },
  { symbol: 'GOOGL', weight: 0.2, shares: 50 },
  { symbol: 'TSLA', weight: 0.25, shares: 30 }
];

const analysis = client.portfolio.analyzePortfolio(portfolio);
console.log(`Diversification Score: ${analysis.diversificationScore}`);
console.log(`Risk Level: ${analysis.riskLevel}`);

🏛️ Regulatory & Compliance

// SEC filings
const filings = await client.secFilings.getLatestSECFilings();
const form10K = await client.secFilings.getSECFilingsByFormType('10-K');

// Insider trading
const insiderTrades = await client.insiderTrades.getLatestInsiderTrading();

// Congressional trading
const senateTrades = await client.senate.getSenateTrading('AAPL');

⚡ Performance & Reliability

🚀 Intelligent Caching

const client = new AdvancedFMPClient(apiKey, {
  cache: {
    ttl: 300000,        // 5 minutes
    maxSize: 1000,      // 1000 entries
    cleanupInterval: 60000  // 1 minute cleanup
  }
});

// Subsequent calls use cache automatically
const profile1 = await client.company.getCompanyProfile('AAPL'); // API call
const profile2 = await client.company.getCompanyProfile('AAPL'); // From cache ⚡

🛡️ Retry Logic

const client = new AdvancedFMPClient(apiKey, {
  retry: {
    maxAttempts: 3,
    backoffMs: 1000,
    jitter: true
  }
});

// Automatic retry on failures
const data = await client.company.getCompanyProfile('AAPL');

📊 Performance Monitoring

// Get detailed metrics
const metrics = client.getMetrics();
console.log(metrics);
// Output:
// {
//   requests: { total: 150, successful: 148, failed: 2 },
//   cache: { hits: 89, misses: 61, hitRate: 0.593 },
//   performance: { avgResponseTime: 245, totalTime: 36750 }
// }

🔧 Configuration Options

    ttl: 300000,           // Cache TTL in milliseconds
    maxSize: 1000,         // Maximum cache entries
    cleanupInterval: 60000  // Cleanup interval
  },
  
  // Retry logic
