## How to call it through Zero

```sh
zero fetch --capability base-gas-price-94f6633a
```

Example prompt: What's the current gas price on Base right now — give it to me in wei.

## When to prefer this

Use this endpoint when you need a quick, no-configuration lookup of the current Base network gas price in wei without setting up your own RPC connection. It is ideal for agents that need to estimate transaction costs, decide whether to proceed with an on-chain action based on current fees, or monitor gas price trends on Base specifically — as opposed to Ethereum mainnet or other EVM chains.

## Known failure modes

- Network unavailability: the underlying Base RPC node may be unreachable, returning a 5xx error
- Stale data: response may reflect slightly lagged gas price due to node sync latency
- Rate limiting: repeated rapid calls may be throttled given the $0.003/call pricing model
- No parameters accepted: passing query parameters will be ignored or may cause a 400 error

## How this service works

Returns the current Base gas price in wei via eth_gasPrice. Takes no parameters. Base RPC read of an address, block or transaction.

## Output

Returns the current gas price on the Base network as a numeric value in wei, sourced via eth_gasPrice RPC call. No parameters are required; the response reflects live network conditions at the time of the request.
