Track top meme coin prices with Telegram Bot and CoinGecko API
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"]["text"]}} === "/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.
