CoinGecko API: A Complete Guide

What Is the CoinGecko API?

The CoinGecko API enables developers to programmatically access cryptocurrency data—including prices, trading volumes, market capitalization, and exchange metrics—directly from CoinGecko's extensive database.

CoinGecko serves as a comprehensive crypto data provider, offering real-time pricing, historical charts, exchange listings, and market analytics. This guide demonstrates how to leverage its API using Python for data extraction and analysis.

Getting Started with CoinGecko API

1. Sign Up: Create an account on CoinGecko’s website to access the API.

2. Installation: Use Python’s pycoingecko library for seamless integration:

   from pycoingecko import CoinGeckoAPI
   cg = CoinGeckoAPI()

How to Fetch Price Data Using the CoinGecko API

Single Currency Price Check

Retrieve Bitcoin’s USD price with a simple API call:

cg.get_price(ids='bitcoin', vs_currencies='usd')

Multi-Currency Price Data

Fetch prices for multiple cryptocurrencies (e.g., Bitcoin, Ethereum, Litecoin):

cg.get_price(ids=['bitcoin', 'ethereum', 'litecoin'], vs_currencies='usd')

Alternatively:

cg.get_price(ids='bitcoin,litecoin,ethereum', vs_currencies='usd')

Advanced Price Metrics

Include additional parameters like market cap, 24-hour volume, and price changes:

cg.get_price(
    ids='bitcoin',
    vs_currencies='usd',
    include_market_cap='true',
    include_24hr_vol='true',
    include_24hr_change='true'
)

Retrieving Historical Data

Daily Historical Snapshot

Get Bitcoin’s market data for a specific date (e.g., November 10, 2020):

data = cg.get_coin_history_by_id(
    id='bitcoin',
    date='10-11-2020',
    localization='false'
)

Time-Series Market Charts

Fetch 3-day price history with 24-hour volume:

cg.get_coin_market_chart_by_id(
    id='bitcoin',
    vs_currency='usd',
    days='3'
)

Custom UNIX Timestamp Range

Pull data for a precise time window:

cg.get_coin_market_chart_range_by_id(
    id='bitcoin',
    vs_currency='usd',
    from_timestamp='1605096000',
    to_timestamp='1605099600'
)

Listing Supported Coins and Exchanges

Get All Available Coins

cg.get_coins_list()

Market Data for Top Cryptos

List all coins with USD metrics:

cg.get_coins_markets(vs_currency='usd')

Spot Data for a Specific Coin

Fetch detailed Bitcoin metrics:

cg.get_coin_by_id(id='bitcoin')

Exchange-Specific Data

Retrieve Binance’s top 100 tickers and BTC volume:

data_binance = cg.get_exchanges_by_id('binance')

Understanding CoinGecko’s Trust Score

The Trust Score evaluates exchanges based on:

• Liquidity depth
• Order book spread
• Cybersecurity measures
• Web traffic validity
  It combats inflated volumes from wash trading and unreliable platforms.

Integrating CoinGecko Data into Google Sheets

1. Open Google Sheets > Tools > Script Editor.

2. Paste this script to import JSON data:

   function IMPORTJSON(url, xpath) {
     try {
       var res = UrlFetchApp.fetch(url);
       var json = JSON.parse(res.getContentText());
       var pathArray = xpath.split(".");
       for (var i = 0; i < pathArray.length; i++) {
         json = json[pathArray[i]];
       }
       return json;
     } catch (e) {
       return "Error: " + e;
     }
   }

3. Use the custom function =IMPORTJSON() to pull live crypto data.
