​
Quick Start

​
Basic Usage

package main

import (
    "fmt"
    "log"

    "github.com/coinpaprika/coinpaprika-api-go-client/v2/coinpaprika"
)

func main() {
    // Initialize the client
    client := coinpaprika.NewClient(nil)

    // Get all tickers
    tickers, err := client.Tickers.List(nil)
    if err != nil {
        log.Fatal(err)
    }

    // Display first 3 coins
    for idx, ticker := range tickers {
        if ticker.Name == nil || ticker.Symbol == nil || ticker.Rank == nil {
            continue
        }

        fmt.Println("Name:", *ticker.Name)
        fmt.Println("Symbol:", *ticker.Symbol)
        fmt.Println("Rank:", *ticker.Rank)
        
        if quoteUSD, ok := ticker.Quotes["USD"]; ok && quoteUSD.Price != nil {
            fmt.Printf("Price: %.2f USD\n\n", *quoteUSD.Price)
        }

        if idx >= 2 {
            break
        }
    }
}

​
Using Custom HTTP Client

    "github.com/coinpaprika/coinpaprika-api-go-client/v2/coinpaprika"
)

func main() {
    // Create custom HTTP client with timeout
    customClient := &http.Client{
        Timeout: 10 * time.Second,
    }

    // Initialize CoinPaprika client with custom HTTP client
    client := coinpaprika.NewClient(customClient)

    // Get global market data
    global, err := client.Global.Get()
    if err != nil {
        log.Fatal(err)
    }

    fmt.Printf("Total market cap: $%.0f\n", *global.MarketCapUSD)

    ohlcv, err := client.Coins.GetHistoricalOHLCVByCoinID("btc-bitcoin", &coinpaprika.HistoricalOHLCVOptions{
        Quote: "usd",
        Start: startTime,
        End:   endTime,

    "log"

    "github.com/coinpaprika/coinpaprika-api-go-client/v2/coinpaprika"
)

func main() {

        Limit:      5,

        QuoteCurrencyID: "eth-ethereum",
        Amount:          1,
    })
    if err != nil {
        log.Fatal(err)
    }

    fmt.Printf("1 BTC = %.6f ETH\n", conversion.Price)
}

​
Error Handling

package main

import (
    "fmt"
    "log"

    "github.com/coinpaprika/coinpaprika-api-go-client/v2/coinpaprika"
)

func main() {
    client := coinpaprika.NewClient(nil)

    // Handle errors gracefully
    coin, err := client.Coins.GetByID("invalid-coin-id")
    if err != nil {
        // The client returns a standard error, which may include the HTTP status code from the API.
        log.Printf("An error occurred: %v", err)
        return
    }

    fmt.Printf("Coin: %s\n", *coin.Name)
}

​
Advanced Usage

​
Rate Limiting

The client does not automatically handle rate limiting. If you exceed the request limit for your plan, the API will return an error with an HTTP 429 “Too Many Requests” status code. Your application should handle these errors, for example by implementing a backoff-and-retry mechanism.

​
Custom Request Options

package main

import (
	"log"

	"github.com/coinpaprika/coinpaprika-api-go-client/v2/coinpaprika"
)

func main() {
    client := coinpaprika.NewClient(nil)

    // Get tickers with custom options
    options := &coinpaprika.TickersOptions{
        Quotes: "USD,BTC",
    }

    tickers, err := client.Tickers.List(options)
    if err != nil {
        panic(err)
    }

    // Process tickers...
	log.Printf("Fetched %d tickers", len(tickers))
}
