Functions exposed to the LLM to take actions

Name	Description
get_current_gasA	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_gasA	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_priceA	Get the current ETH/USD spot price and its 24-hour change.
best_time_to_transactA	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_costA	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.
