Building a Crypto Telegram Bot with Real-Time Price Updates Utilizing Python

使用 Python 建立具有即時價格更新的加密電報機器人

In the rapidly evolving world of cryptocurrencies, staying abreast of market fluctuations and asset performance is paramount. To address this need, we present a comprehensive guide on constructing a Telegram bot that empowers users with real-time cryptocurrency updates. This bot not only provides instant access to current prices but also offers a wealth of additional information, such as market capitalization, trading volume, and historical price data.

在快速發展的加密貨幣世界中，及時了解市場波動和資產表現至關重要。為了滿足這一需求，我們提供了有關構建 Telegram 機器人的綜合指南，該機器人為用戶提供即時加密貨幣更新。該機器人不僅可以即時存取當前價格，還可以提供大量附加信息，例如市值、交易量和歷史價格數據。

Functionality Overview

功能概述

Our Telegram Crypto Bot boasts an array of features designed to provide a comprehensive and real-time overview of the crypto market:

我們的 Telegram Crypto Bot 擁有一系列功能，旨在提供加密市場全面、即時的概覽：

• Real-Time Crypto Market Data Retrieval: The bot seamlessly fetches and displays real-time market data for various cryptocurrencies, including current price, market cap, volume, and price change percentage.
• 24h High/Low Prices: Users can access the highest and lowest prices of a specific cryptocurrency over the past 24 hours, a crucial piece of information for active traders and investors.
• Supply Information: The bot retrieves and presents the circulating supply and total supply of a selected cryptocurrency, offering insights into its scarcity.
• Top Cryptocurrencies: To provide a quick overview of the leading cryptocurrencies, the bot displays the top 10 coins based on market cap.
• On-Chain DEX Pool Data: This advanced feature enables users to explore on-chain Decentralized Exchange (DEX) crypto liquidity pools, providing valuable insights into the DEX market.

Prerequisites

即時加密貨幣市場數據檢索：機器人無縫獲取並顯示各種加密貨幣的即時市場數據，包括當前價格、市值、交易量和價格變化百分比。 24 小時內特定加密貨幣的價格，這對於活躍交易者和投資者來說是至關重要的資訊。稀缺性。貨幣流動性池，提供有價值的資訊對 DEX 市場的洞察。

Before embarking on this project, ensure that the following prerequisites are met:

在開始此專案之前，請確保滿足以下先決條件：

• Python 3.7 or higher installed on your system. Python is a versatile and beginner-friendly programming language that will serve as the foundation for our bot.
• Telegram account. Telegram is a cloud-based instant messaging platform where our bot will reside.
• Basic understanding of Python programming. While this guide will provide in-depth instructions, a foundational understanding of Python syntax and concepts will enhance your experience.
• Text editor: Choose a text editor or Integrated Development Environment (IDE) of your choice, such as Visual Studio Code, Sublime Text, or Atom, to write your code.
• CoinGecko API: We will leverage the CoinGecko API to fetch the necessary crypto market data. CoinGecko offers a free Demo plan, providing 30 calls per minute and a monthly cap of 10,000 calls. Register for a CoinGecko account and apply for the Demo plan to obtain your API key.

Step 1: Telegram Bot Setup

您的系統上安裝了 Python 3.7 或更高版本。 Python 是一種多功能且適合初學者的程式語言，將作為我們 bot.Telegram 帳戶的基礎。 Telegram 是一個基於雲端的即時通訊平台，我們的機器人將駐留在其中。雖然本指南將提供深入的說明，但對Python 語法和概念的基本了解將增強您的體驗。 、或 Atom，編寫您的程式碼。 CoinGecko提供免費的演示計劃，每分鐘提供30次調用，每月上限為10,000次調用。註冊 CoinGecko 帳戶並申請示範計畫以取得您的 API 金鑰。

1. Create a new bot on Telegram by searching for 'BotFather' and following the prompts. Provide a name and username for your bot.
2. Upon successful creation, you will receive a token, which serves as your bot's authentication key for Telegram API requests.

Step 2: Installing Python Libraries

透過搜尋「BotFather」並按照提示操作，在 Telegram 上建立一個新機器人。為您的機器人提供名稱和使用者名稱。

We will utilize two essential Python libraries:

我們將利用兩個重要的 Python 函式庫：

1. python-telegram-bot: This library facilitates interaction with the Telegram API.
2. requests: This library empowers HTTP requests to the CoinGecko API.

Install these libraries using pip:

python-telegram-bot：此程式庫促進與 Telegram API 的交互。

pip install python-telegram-bot requests

Step 3: Fetching Cryptocurrency Data

pip install python-telegram-bot requests第 3 步：取得加密貨幣數據

To access cryptocurrency data, we will employ the CoinGecko API, which provides comprehensive market insights beyond price information.

為了存取加密貨幣數據，我們將使用 CoinGecko API，它提供除價格資訊之外的全面市場洞察。

Step 4: Writing the Bot Code

第 4 步：編寫機器人程式碼

Now that our bot is set up and the libraries are installed, let's delve into the Python code:
