Real-World Applications: Where This SDK Makes a Difference

1. High-Frequency Trading Systems

For algorithmic traders, speed and accuracy are everything:

// Real-time price monitoring for trading decisions
cg := coingecko.New(coingecko.WithProAPI(true), coingecko.WithAPIKey(apiKey))

// Get multiple coin prices simultaneously
prices, err := cg.Simple().Price(
    []string{"bitcoin", "ethereum", "solana"},
    []string{"usd", "eur"},
    &coingecko.SimplePriceOptions{
        IncludeMarketCap:   true,
        Include24hrVol:     true,
        Include24hrChange:  true,
    },
)

// Execute trading logic based on real-time data
for coinID, data := range prices {
    if data["usd"].(float64) > buyThreshold {
        executeBuyOrder(coinID, data["usd"].(float64))
    }
}

2. Portfolio Management Platforms

Track and analyze crypto investments across multiple assets:

// Comprehensive portfolio tracking
holdings := map[string]float64{
    "bitcoin":  0.5,
    "ethereum": 10,
    "cardano":  1000,
}

// Get current portfolio value
coinIDs := make([]string, 0, len(holdings))
for coinID := range holdings {
    coinIDs = append(coinIDs, coinID)
}

prices, err := cg.Simple().Price(coinIDs, []string{"usd"}, nil)
totalValue := calculatePortfolioValue(holdings, prices)

// Historical performance analysis
chartData, err := cg.Coins().MarketChart("bitcoin", "usd", "30", nil)
analyzePerformance(chartData)

3. DeFi Analytics and Monitoring

Build sophisticated DeFi tracking applications:

// Track DeFi tokens and metrics
defiCategory := "decentralized-finance-defi"
markets, err := cg.Coins().Markets("usd", &coingecko.MarketsOptions{
    Category: &defiCategory,
    PerPage:  intPtr(100),
})

// Monitor specific DeFi protocols
uniToken, err := cg.Contract().Coin(
    "ethereum",
    "0x1f9840a85d5af5bf1d1762f925bdaddc4201f984", // UNI token
)

// Global DeFi market metrics
globalDeFi, err := cg.Global().DeFi()

4. NFT Market Analysis

Access comprehensive NFT data and analytics:

// Get NFT collection data
nfts, err := cg.NFTs().List("ethereum", &coingecko.NFTsListOptions{
    Order: "volume_24h_desc",
    PerPage: intPtr(50),
})

// Analyze NFT market trends
for _, nft := range nfts {
    floorPrice := nft["floor_price"].(map[string]interface{})["usd"].(float64)
    volume24h := nft["volume_24h"].(map[string]interface{})["usd"].(float64)

    if volume24h > volumeThreshold {
        alertNFTActivity(nft)
    }
}

Technical Deep Dive: Modern Go Development Practices

Clean Architecture Implementation

The SDK follows Go idioms and clean architecture principles:

// Service-based design for clear separation of concerns
cg := coingecko.New(
    coingecko.WithAPIKey(apiKey),
    coingecko.WithProAPI(true),
    coingecko.WithTimeout(30*time.Second),
)

// Each service handles a specific domain
simpleService := cg.Simple()      // Quick price lookups
coinsService := cg.Coins()        // Comprehensive coin data
contractService := cg.Contract()  // Smart contract tokens
globalService := cg.Global()      // Market-wide metrics

Advanced Configuration for Production

// Production-ready HTTP client configuration
httpClient := &http.Client{
    Timeout: 60 * time.Second,
    Transport: &http.Transport{
        MaxIdleConns:        100,
        MaxIdleConnsPerHost: 10,
        IdleConnTimeout:     90 * time.Second,
    },
}

cg := coingecko.New(
    coingecko.WithHTTPClient(httpClient),
    coingecko.WithAPIKey(os.Getenv("COINGECKO_API_KEY")),
    coingecko.WithProAPI(true),
)

Error Handling Best Practices

// Comprehensive error handling for production
prices, err := cg.Simple().Price(coinIDs, currencies, nil)
if err != nil {
    // Log error for monitoring
    log.Printf("CoinGecko API error: %v", err)

    // Implement fallback mechanism
    if isRetryableError(err) {
        return fetchWithRetry(coinIDs, currencies)
    }

    // Use cached data if available
    return getCachedPrices(coinIDs, currencies)
}

WebSocket Streaming for Real-Time Data

// Real-time price updates via WebSocket
stream := cg.NewWebSocket()
if err := stream.Connect(); err != nil {
    log.Fatal(err)
}

// Subscribe to price updates
stream.SubscribePrice("bitcoin", "usd")
stream.SubscribePrice("ethereum", "usd")

stream.OnPriceUpdate(func(coin, currency string, price float64) {
    // Handle real-time price updates
    updateTradingSignals(coin, currency, price)
    alertPriceChanges(coin, currency, price)
})

Getting Started: Your First Crypto Application

Installation and Basic Setup

# Install the SDK
go get github.com/tigusigalpa/coingecko-go

# Initialize your Go module
go mod init your-crypto-app
go mod tidy

Basic Usage: Free API

package main

import (
    "fmt"
    "log"
    coingecko "github.com/tigusigalpa/coingecko-go"
)

func main() {
    // Create client (no API key needed for free tier)
    cg := coingecko.New()

    // Get Bitcoin price
    prices, err := cg.Simple().Price(
        []string{"bitcoin"},
        []string{"usd"},
        nil,
    )
    if err != nil {
        log.Fatal(err)
    }

    fmt.Printf("Bitcoin: $%.2f\n", prices["bitcoin"]["usd"])
}

Pro API Configuration

// Unlock higher rate limits with Pro API
cg := coingecko.New(
    coingecko.WithAPIKey(os.Getenv("COINGECKO_API_KEY")),
    coingecko.WithProAPI(true),
)

// Check API usage
usage, err := cg.Ping().APIUsage()
if err != nil {
    log.Fatal(err)
}

fmt.Printf("API calls remaining: %d\n", usage["remaining_calls"])

Performance and Scalability Considerations

Intelligent Caching Strategy

// Implement caching to respect rate limits
type CachedPrice struct {
    Data      map[string]map[string]interface{}
    Timestamp time.Time
}

var (
    priceCache = make(map[string]*CachedPrice)
    cacheMutex sync.RWMutex
    cacheTTL   = 5 * time.Minute
)

func getCachedPrice(cg *coingecko.CoinGecko, coinID, currency string) (map[string]map[string]interface{}, error) {
    cacheKey := fmt.Sprintf("%s_%s", coinID, currency)

    cacheMutex.RLock()
    cached, exists := priceCache[cacheKey]
    cacheMutex.RUnlock()

    if exists && time.Since(cached.Timestamp) < cacheTTL {
        return cached.Data, nil
    }

    // Fetch fresh data
    prices, err := cg.Simple().Price([]string{coinID}, []string{currency}, nil)
    if err != nil {
        return nil, err
    }

    // Update cache
    cacheMutex.Lock()
    priceCache[cacheKey] = &CachedPrice{
        Data:      prices,
        Timestamp: time.Now(),
    }
    cacheMutex.Unlock()

    return prices, nil
}

Concurrent Data Processing

// Process multiple coins concurrently
func fetchMultiplePrices(cg *coingecko.CoinGecko, coinIDs []string) (map[string]map[string]interface{}, error) {
    var wg sync.WaitGroup
    results := make(map[string]map[string]interface{})
    resultsMutex := sync.Mutex{}

    for _, coinID := range coinIDs {
        wg.Add(1)
        go func(id string) {
            defer wg.Done()

            prices, err := cg.Simple().Price([]string{id}, []string{"usd"}, nil)
            if err != nil {
                log.Printf("Error fetching %s: %v", id, err)
                return
            }

            resultsMutex.Lock()
            results[id] = prices[id]
            resultsMutex.Unlock()
        }(coinID)
    }

    wg.Wait()
    return results, nil
}

Cross-Platform Development: PHP/Laravel Integration

For teams working across multiple programming languages, the CoinGecko ecosystem provides consistent experiences. The same comprehensive API coverage is available in PHP/Laravel through the CoinGecko PHP SDK (github.com/tigusigalpa/coingecko-php).

PHP/Laravel Integration Example

// Laravel usage with Facade
use Tigusigalpa\CoinGecko\Facades\CoinGecko;

// Get Bitcoin price
$price = CoinGecko::simple()->price(['bitcoin'], ['usd']);

// Get market data
$markets = CoinGecko::coins()->markets('usd', [
    'per_page' => 100,
    'order' => 'market_cap_desc'
]);

// Portfolio tracking in PHP
$portfolio = [
    'bitcoin' => 0.5,
    'ethereum' => 10,
];

$totalValue = 0;
foreach ($portfolio as $coin => $amount) {
    $price = CoinGecko::simple()->price([$coin], ['usd']);
    $totalValue += $price[$coin]['usd'] * $amount;
}

// Never hardcode API keys
type Config struct {
    CoinGeckoAPIKey string `env:"COINGECKO_API_KEY,required"`
    IsProAPI        bool   `env:"COINGECKO_PRO_API"`
}

func NewClient(cfg Config) *coingecko.CoinGecko {
    options := []coingecko.Option{
        coingecko.WithTimeout(30 * time.Second),
    }

    if cfg.CoinGeckoAPIKey != "" {
        options = append(options,
            coingecko.WithAPIKey(cfg.CoinGeckoAPIKey),
            coingecko.WithProAPI(cfg.IsProAPI),
        )
    }

    return coingecko.New(options...)
}

Monitoring and Observability

// Implement comprehensive monitoring
func monitoredAPICall(operation string, fn func() (interface{}, error)) (interface{}, error) {
    start := time.Now()
    defer func() {
        duration := time.Since(start)
        metrics.RecordAPICall("coingecko", operation, duration)
    }()

    result, err := fn()
    if err != nil {
        metrics.RecordAPIError("coingecko", operation, err)
        return nil, err
    }

    return result, nil
}
