Track Top Meme Coin Prices with Telegram Bot and CoinGecko API

Description

Platform: n8n (Telegram Bot Integration)
Purpose: Let users fetch top meme coin prices in real-time using a simple /memecoin Telegram command
How It Works (Logic Breakdown)
This flow listens for a Telegram command and fetches data from the CoinGecko API to respond with live memecoin prices.

🔹 1. Telegram Trigger Node
Listens for incoming Telegram messages from users.

Activated when a message is sent in a Telegram chat connected to the bot.

Passes the raw message (e.g., /memecoin) to the next node.

🔹 2. IF Node – Check if Message is /memecoin
Condition: {{$json"message"}} === "/memecoin"

If true ➝ continue to fetch data from CoinGecko.

If false ➝ nothing happens.

🔹 3. HTTP Request – Fetch Meme Coins from CoinGecko
API: https://api.coingecko.com/api/v3/coins/markets?...category=meme-token

Fetches top 5 meme tokens by market cap.

Data includes:

Name

Symbol

Current price (USD)

Coin ID (for URL linking)

🔹 4. Function Node – Format the Message
Parses the JSON response from CoinGecko.

Builds a clean message like:

ruby
Copy
Edit
🚀 Dogecoin (DOGE)
💰 Price: $0.123
🔗 More: https://www.coingecko.com/en/coins/dogecoin
Loops through top 5 meme coins and adds line breaks.

🔹 5. Telegram Send Node – Reply to User
Sends the formatted message to the original chat.

Uses chat_id from the trigger to ensure correct user receives it.
