## 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 base-l2-gas-price-current-3b7fcc1a
```

Example prompt: What's the current gas price on Base L2 right now in gwei? I want to know if it's a good time to submit a transaction.

## When to prefer this

Use this endpoint when you need a real-time, on-chain gas price for the Base L2 network specifically — ideal for agents deciding when to submit transactions, estimating transaction costs, or monitoring gas conditions on Base.

## Known failure modes

- RPC node unavailable — chain state cannot be read, returns error
- Network congestion causes stale or delayed gas price reading
- Invalid or unexpected response from underlying Base RPC endpoint

## How this service works

EVM gas oracle for any major chain - Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Avalanche: next-block baseFee plus slow, med and fast priority-fee tiers (maxFeePerGas and maxPriorityFeePerGas), read live from chain state in one call. Choose network (default Ethereum). EIP-1559 and legacy handled.

## Output

Returns the current gas price on the Base L2 network expressed in gwei, as read directly from live chain state using eth_gasPrice.
