​
CoinPaprika JavaScript SDK

The official Node.js client library for the CoinPaprika API provides convenient access to cryptocurrency market data.

​
Installation

Install the CoinPaprika JavaScript SDK using npm: 
npm install @coinpaprika/api-nodejs-client

​
Quick Start

The following example shows how to create a client instance and fetch global market data and a list of all tickers.

​
Using Promises

const CoinpaprikaAPI = require('@coinpaprika/api-nodejs-client');

const client = new CoinpaprikaAPI();

// Get global market data
client.getGlobal()
  .then(console.log)
  .catch(console.error);

// Get all tickers
client.getAllTickers()
  .then(console.log)
  .catch(console.error);

​
Using Async/Await

const CoinpaprikaAPI = require('@coinpaprika/api-nodejs-client');

async function getMarketData() {
  const client = new CoinpaprikaAPI();
  
  try {
    // Get global market overview
    const globalData = await client.getGlobal();
    console.log('Global Market Data:', globalData);

    // Get all coins
    const coins = await client.getCoins();
    console.log(`\nFound ${coins.length} coins`);
    
  } catch (error) {
    console.error('Error fetching market data:', error);
  }
}

getMarketData();

​
Common Use Cases

​
Getting Coin Information

Fetch a list of all available coins and find a specific one by its ID. 
const CoinpaprikaAPI = require('@coinpaprika/api-nodejs-client');

const client = new CoinpaprikaAPI();

async function getCoinInfo() {
  try {
    // Get a specific coin by its ID
    const bitcoin = await client.getCoin('btc-bitcoin');
    console.log('Bitcoin Details:', bitcoin);

  } catch (error) {
    console.error('Error fetching coin info:', error);
  }
}

getCoinInfo();

​
Getting Ticker Data

Fetch ticker information for all coins or for a specific coin. 
const CoinpaprikaAPI = require('@coinpaprika/api-nodejs-client');

const client = new CoinpaprikaAPI();

async function getTickerData() {
  try {
    // Get tickers for all coins, quoted in USD and BTC
    const allTickers = await client.getAllTickers({
      quotes: ['USD', 'BTC']
    });
    console.log('All Tickers Count:', allTickers.length);

    // Get a specific ticker by coin ID
    const btcTicker = await client.getAllTickers({
      coinId: 'btc-bitcoin'
    });
    console.log('\nBitcoin Ticker:', btcTicker);
    
  } catch (error) {
    console.error('Error fetching ticker data:', error);
  }
}

getTickerData();

​
Historical OHLCV Data

Fetch historical Open-High-Low-Close-Volume (OHLCV) data for a specific coin. 
const CoinpaprikaAPI = require('@coinpaprika/api-nodejs-client');

const client = new CoinpaprikaAPI();

async function getHistoricalData() {
  try {
    // Get historical OHLCV data for Bitcoin for a specific date range
    const ohlcvData = await client.getCoinsOHLCVHistorical({
      coinId: "btc-bitcoin",
      quote: "usd",
      start: "2023-01-01",
      end: "2023-01-07"
    });

    console.log('Bitcoin OHLCV Data (First week of 2023):');
    console.log(ohlcvData);

  } catch (error) {
    console.error('Error fetching historical data:', error);
  }
}

getHistoricalData();

​
Historical Ticker Data

Fetch historical ticker data for a specific coin within a date range and at a given interval. 
const CoinpaprikaAPI = require('@coinpaprika/api-nodejs-client');

const client = new CoinpaprikaAPI();

async function getHistoricalTicker() {
  try {
    // Get historical tickers for Bitcoin
    const historicalTickers = await client.getAllTickers({
      coinId: 'btc-bitcoin',
      historical: {
        start: '2023-01-01',
        end: '2023-01-02',
        limit: 10,
        quote: 'usd',
        interval: '1h'
      }
    });

    console.log(`\nHistorical tickers found:`, historicalTickers);

  } catch (error) {
    console.error('Error fetching historical tickers:', error);
  }
}

getHistoricalTicker();

​
Error Handling

The client returns a Promise, so you can handle errors by chaining a .catch() block or by using a try...catch block with async/await. The error object from the underlying node-fetch library will contain details about the failure. 
const CoinpaprikaAPI = require('@coinpaprika/api-nodejs-client');

const client = new CoinpaprikaAPI();

async function handleErrors() {
  try {
    // This will fail because the coin ID does not exist
    await client.getCoin('invalid-coin-id');
  } catch (error) {
    // The API returns an error object, e.g., { error: 'id not found' }
    console.error('Error caught:', error);
  }
}

handleErrors();
