# ETH Gas Cost Calculator

> ETH Gas Cost Calculator is a paid API for AI agents from kihustle.tech, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-25).

Calculates the USD cost of an Ethereum transaction given gas units, gas price in Gwei, and current ETH price

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability eth-gas-cost-calculator-d2ddb13c -d '<json body>'
```

Example prompt: Calculate how much a transaction costing 21000 gas units would cost in dollars if the gas price is 35 gwei and ETH is currently trading at $3200.

## When to prefer this

Use this endpoint when you need a quick, programmatic USD cost estimate for an Ethereum transaction and already know the gas units required, current gwei price, and ETH/USD rate. It is best suited for lightweight fee-transparency checks in DeFi workflows, NFT minting UIs, or agent-driven transaction cost guards. Prefer this over on-chain RPC calls when you want a simple arithmetic computation without needing real-time gas oracle data.

## Known failure modes

- Missing required fields (gas_units, gwei_price, or eth_price_usd) result in an error response
- Non-integer gas_units value may cause a validation error
- Negative or zero values for price inputs may return unexpected results
- Payment failure (insufficient USDC) blocks the request with a 402 response
- Response schema is minimal — detailed error messages may not be provided

## Output

Returns a JSON object with a result field containing the computed gas cost and a status field indicating success. The computed cost represents the total USD cost of the transaction based on the provided gas units, gwei price, and ETH/USD exchange rate.
