API Documentation

This serves as a guide for the provided Flask API .

Introduction

This API offers functionalities related to reviews and token information retrieval . The code uses Flask for the web framework and interacts with an external service (DexScreener) through websockets for retrieving token data .

API Endpoints

• Root (/) (GET):

  • Returns a basic message acknowledging a user's access to the API. Cool!

• Dex (/dex) (GET):

  • Retrieves token information from DexScreener.
  • If successful, returns a message indicating the dex endpoint has been accessed. In case of errors, an error message is printed. Dex endpoint accessed! ✅ Error! ⚠️

Code Structure

• Flask App Setup

  • Initializes the Flask application and defines routes for the API endpoints.

• Routes

  • Each endpoint definition includes a docstring explaining its functionality and behavior.
  • Error handling is implemented to capture exceptions and return appropriate error messages.

External Libraries

• Flask: Web framework for building web applications (https://flask.palletsprojects.com/en/2.3.x/)
• api.dex: Assumed to contain functionalities related to DexBot class and token retrieval.
• websockets: Library for establishing websocket connections (https://readthedocs.org/projects/websockets/) ️
• telebot: Library for interacting with the Telegram bot API (https://pypi.org/project/pyTelegramBotAPI/)
• datetime: Library for working with date and time objects (built-in Python module). ️
• os: Library for interacting with the operating system (built-in Python module). ️

Environment Variables

• API: Stores the Telegram bot API key.
• ID: Stores the Telegram channel ID for sending messages.
• ADDRESS: Stores the Address of the dexscreener websocket. It is custom defined.

DexBot Class

This class facilitates communication with DexScreener for retrieving token information.

• init(self, api_key, channel_id, chain=False, max_token=10):

  • Initializes the class with the provided API key, channel ID, optional chain parameter (for filtering tokens by chain), and the maximum number of tokens to retrieve. ℹ️

• connect(self): (Asynchronous function)

  • Establishes a websocket connection with DexScreener and returns the initial response data. ️ ✨

• tg_send(self, message):

  • Sends a message to the specified Telegram channel using the Telegram bot API.

• token_getter(self):

  • Retrieves token information from DexScreener using a websocket connection.
  • Parses the response data and formats it into a markdown string containing details like token name, price, market cap, etc. 🪄 ✨
  • Returns the formatted markdown string containing token information.

NOTE 🗒

If you want to run on a specific chain, define the chain in the class. You should ping the /dex path inorder to run the dexscreener scraper. You can use cronjob it works great.
