How this service works
Estimated Base execution-gas cost of a settlement transaction (e.g. an ERC-3009 transferWithAuthorization), computed from our own current base-fee and ETH/USD observations. Execution gas only -- excludes priority fee and the Base L1 data fee, so treat this as a lower-bound estimate. Useful for micropayment break-even decisions. Descriptive statistics only; not investment advice.
Output
Returns descriptive statistics about the estimated execution gas cost for a Base settlement transaction: the USD and ETH amounts, the current base fee used, the ETH/USD rate observed, and the gas unit count. Excludes priority fee and L1 data fee, so the result is a lower-bound estimate useful for micropayment break-even analysis.
Example use cases
Example prompt
“What's the current estimated USD cost of a Base settlement transaction — assume a standard 65000 gas units for an ERC-3009 transferWithAuthorization — so I can decide if this micropayment is worth executing?”
Technical details
Endpoint
GEThttps://api.agentfeeds.jp/v1/x402/gas/settlement_costWhen to prefer
Use this endpoint when you need a quick, live lower-bound estimate of the execution gas cost for a Base settlement transaction in USD or ETH — especially for x402/ERC-3009 micropayment break-even decisions. Prefer this over on-chain RPC calls when you need both the ETH gas cost and its USD equivalent in a single call without managing price feeds yourself.
Side effects
- Invalid gas_units value outside 1000–2000000 range returns a 400 error
- Base fee or ETH/USD data temporarily unavailable returns a 503 or stale-data error
- Payment not received or invalid x402 payment header returns a 402 error
