## 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 gateway-spraay-app-7adabaaf
```

Example prompt: What are the current gas prices on Base right now? I want to know if it's a good time to submit my transaction.

## When to prefer this

Use this endpoint when you need real-time gas price data specifically for the Base (Coinbase L2) network, for example before submitting a transaction, estimating fees, or deciding whether to wait for lower congestion. Prefer this over Ethereum mainnet gas oracles when operating on Base.

## Known failure modes

- Base RPC node unavailable — upstream error fetching on-chain gas data
- Payment not processed — x402 payment of $0.005 USDC required
- Rate limit or invalid request format
