## 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 kihustle-eth-gas-cost-calculator-265827da -d '<json body>'
```

Example prompt: How much would an Ethereum transaction cost in USD if it uses 21000 gas units at 30 Gwei, with ETH currently priced at $3200?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
