ETH Gas Price Tracker & Alert

Save on transaction fees. This workflow polls the Etherscan or EthGasStation API for current "Low", "Standard", and "Fast" gwei prices. If the current "Standard" price is lower than your pre-set threshold (e.g., 20 gwei), it sends an urgent notification to your Telegram so you can execute your transactions cheaply.
