## 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 xerxes-ethereum-gas-price-eth-gasprice-08b35836
```

Example prompt: What's the current Ethereum gas price in wei right now?

## When to prefer this

Use this endpoint when you need a quick, no-parameter lookup of the current Ethereum mainnet gas price in wei — ideal for pre-transaction cost estimation, gas threshold monitoring, or displaying real-time fee data. Prefer this over more complex RPC wrappers when you only need the raw gas price without any address or block context.

## Known failure modes

- Network or RPC node unavailability returns ok:false with an error message
- Rate limiting or payment failure may result in a 402 or error response
- Temporary Ethereum node sync issues may return stale or null hex values

## How this service works

Returns the current gas price on the Ethereum network. No inputs. Output: gas price in wei as a hex string.

## Output

Returns a JSON object with an 'ok' boolean, the current gas price as an integer (in wei) in the 'result' field, a hex-encoded representation in 'hex', the 'chain' identifier (e.g. 'ethereum'), and the 'method' name ('eth_gasPrice'). On failure, 'ok' is false and an 'error' string is present.
