Telegram AI Data Assistant n8n Workflow: GPT-4o + Open-Meteo

Turn your Telegram bot into an AI data assistant for weather, FX, crypto, and Indonesia updates

This n8n workflow connects a Telegram chat to an OpenAI-powered agent that answers natural-language questions with live data from Open-Meteo (weather), Frankfurter (FX rates), CoinGecko (crypto), and Indonesia public data via StudioAPI (including BMKG earthquake data and Bank Indonesia exchange rates).

What this workflow does

• Listens on Telegram: Triggers whenever a new message is received by your Telegram bot.
• Understands the question with OpenAI: Sends the message text to a LangChain-style agent (configured with GPT-4o by default in the workflow context, with gpt-4o-mini noted as the default model) that decides which data source to use.
• Fetches live weather (Open-Meteo): When the user asks about weather, it retrieves current conditions using latitude and longitude.
• Fetches FX or crypto:
  • For FX questions, it pulls USD-based foreign exchange rates from Frankfurter.
  • For crypto questions, it pulls major crypto prices from CoinGecko.
• Answers Indonesia-focused questions: Retrieves the latest Indonesia earthquake data (BMKG source) or Bank Indonesia exchange rates via StudioAPI using x-api-key authentication.
• Responds back in Telegram: Summarizes the results into a short, mobile-friendly reply and sends it to the user.

Use cases

• “Will it rain in Jakarta today?” (Open-Meteo weather via lat/long)
• “What’s the latest USD IDR rate?” (Bank Indonesia via StudioAPI)
• “Show me current FX rates and crypto prices.” (Frankfurter + CoinGecko)
• “Any recent earthquakes in Indonesia?” (BMKG earthquake updates via StudioAPI)
