How this service works
Estimate Base L2 gas costs in ETH and USD for common token operations vs zero-gas facilitator-settled x402 EIP-3009 transfers.
Output
Returns estimated gas costs in both ETH and USD for the requested operation type on Base L2, with comparative data across operation types (eip3009_facilitator, erc20_transfer, eip3009_direct, uniswap_swap) to highlight the cost savings of x402 facilitator-settled transfers.
Example use cases
Compare x402 vs ERC-20 transfer gas costs
“Show me a gas cost comparison between a standard erc20_transfer and an eip3009_facilitator-settled x402 transfer on Base — I want to see the ETH and USD difference.”
Estimate Uniswap swap fees on Base
“How much gas in ETH and USD should I expect to pay for a uniswap_swap on Base L2 right now?”
Evaluate EIP-3009 direct transfer cost
“What's the estimated gas fee in ETH and USD for an eip3009_direct transfer on Base so I can budget micropayment costs for my app?”
