About

Live Ethereum + Layer-2 gas-fee data for AI agents — current gas, cheapest L2, ETH price, best time to transact, and per-action

Explore

- Read-only access; no API key or authentication needed.
- Fetches current Ethereum gas (low/average/high) and ETH price.
- Live Arbitrum, Base, Optimism, and Polygon fee comparisons.
- Suggests whether to send now or wait, with next cheaper window.
- Estimates USD cost of transfers, swaps, NFT mints, or custom gas.

`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_current_gas — current Ethereum gas (low/avg/high Gwei), ETH price, and a send-now-vs-wait call.
- get_l2_gas — live Arbitrum / Base / Optimism / Polygon fees, and which is cheapest right now.
- get_eth_price — current ETH/USD and 24h change.
- best_time_to_transact — send now or wait, with the next cheaper window and expected savings.
- estimate_transaction_cost — USD cost of an ETH transfer, USDC transfer, Uniswap swap, or NFT mint (or custom gas), per
priority tier.
