How this service works
Kostenlose Guides, Solo-Playbooks und Artikel zu KI, Automation und Side Hustles — für Menschen, die mit echten Systemen online Einkommen aufbauen wollen. Transparent finanziert über faire Affiliate-Links.
Output
Returns a JSON object with a 'result' field containing the computed gas cost and a 'status' field confirming success. The primary output is the calculated USD cost of the Ethereum transaction derived from gas_units × gwei_price × 1e-9 × eth_price_usd.
Example use cases
DeFi trade cost estimation
“I'm about to execute a Uniswap swap that uses about 150000 gas. Gas is currently at 45 Gwei and ETH is $3500 — how much will I pay in USD for the transaction fee?”
Smart contract deployment budgeting
“We're deploying a smart contract that will cost roughly 2000000 gas units. Gwei price is 20 right now and ETH is at $2800 — can you tell me the USD cost so I can plan our budget?”
Real-time gas fee dashboard
“Calculate the ETH gas fee in USD for a standard transfer of 21000 gas units at 15 Gwei with ETH at $3100, so I can display it to users on my dashboard.”
Technical details
Endpoint
POSThttps://kihustle.tech/agents/api/v1/eth-gas-cost-calculatorWhen to prefer
Choose this endpoint when you need a lightweight, on-demand computation of Ethereum transaction costs in USD and you already have gas units, Gwei price, and ETH/USD price available. It is ideal for agents building DeFi dashboards, pre-flight transaction cost checks, or budget planning tools. Prefer this over manual arithmetic or general-purpose code execution when you want a dedicated, pay-per-use microservice for this specific calculation.
Side effects
- Missing required fields (gas_units, gwei_price, or eth_price_usd) may result in a computation error or unexpected output
- Negative or zero values for gas_units or gwei_price may produce nonsensical results
- Non-numeric values passed as numbers will likely cause a 400 or processing error
- Payment failure (HTTP 402) if the $0.002 USDC fee is not provided via x402 protocol
