7 tools

• get_current_gas

  Get the current Ethereum mainnet gas price (low / average / high, in Gwei) plus the live ETH/USD price and a send-now-vs-wait recommendation. Use this to answer "what is the gas fee right now".

• get_l2_gas

  Compare live Layer-2 gas fees across Arbitrum, Base, Optimism, and Polygon (Gwei and the estimated wallet fee in USD for a standard transfer), and identify the cheapest right now. Use for "cheapest L2" / "L2 gas fees" questions.

• get_eth_price

  Get the current ETH/USD spot price and its 24-hour change.

• best_time_to_transact

  Find out whether to send a transaction now or wait — returns the current recommendation, expected savings, and when the next cheaper gas window is predicted.

• estimate_transaction_cost

  Estimate the current USD gas cost of a specific Ethereum mainnet action (ETH transfer, ERC-20/USDC transfer, Uniswap swap, or NFT mint), or a custom gas-units amount, at the chosen priority tier.

• get_gas_forecast

  Get the forward-looking hourly Ethereum gas forecast (up to 24 hours ahead) with the predicted cheapest window. Use for "when will gas be cheaper", "should I wait until tomorrow", or planning a transaction.

• get_gas_history

  Get recent historical Ethereum mainnet gas prices over a chosen window, with min/max/average. Use to answer "what has gas been doing", "was gas cheaper yesterday", or to compare the current price against a recent baseline.
