## 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-eth-gas-price-9a30c5c4
```

Example prompt: What's the current gas price on the Base network right now in wei?

## When to prefer this

Choose this endpoint when you need a real-time gas price specifically for the Base (Coinbase L2) network, not Ethereum mainnet. It is ideal for agents that need to estimate transaction fees, gate transactions on low gas, or monitor Base gas conditions programmatically via a simple paid REST interface over x402.

## Known failure modes

- Node unavailable or overloaded — returns 5xx error
- x402 payment failure if USDC balance is insufficient — returns 402 Payment Required
- Malformed request — returns 400 if method or type fields are incorrect
- Stale data if the underlying Base node is lagging behind chain tip

## How this service works

Base gas price via eth_gasPrice for the x402 Bazaar channel; returns the current Base L2 gas price. Base RPC read of an address, block or transaction.

## Output

Returns the current gas price on the Base network as a wei value (integer), equivalent to the response from an eth_gasPrice JSON-RPC call. Useful for fee estimation, transaction cost calculation, and gas monitoring.
