> 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 2026-10-10).

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-59aaf682 -d '<json body>'
```

Example prompt: How much would an Ethereum transaction cost in USD if it uses 21000 gas units at 35 Gwei and ETH is currently trading at $3200?

## When to prefer this

Use this endpoint when you need a quick, on-demand USD cost estimate for an Ethereum transaction and you already have or can fetch the three inputs: gas units, current Gwei price, and current ETH/USD price. Prefer this over doing the math manually when integrating into an automated agent workflow that needs to gate or budget transactions based on cost.

## Known failure modes

- Missing required fields (gas_units, gwei_price, eth_price_usd) may return an error or null result
- Non-integer gas_units value may cause a validation error
- Negative or zero ETH price may produce nonsensical output
- Payment failure (HTTP 402) if USDC payment is not correctly attached via x402 protocol
- Server-side errors (5xx) if the calculation service is unavailable
