## 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-network-gas-price-wallet-health-brief-da1440c4
```

Example prompt: What's the current gas price on Base right now — give me the gwei figure and network status so I can decide whether to submit my transaction.

## When to prefer this

Choose this endpoint when you need real-time gas price data specifically for the Base (Coinbase L2) network and can pay per-call via x402 USDC micropayment with no account signup. Prefer it over general Ethereum gas APIs when Base-specific gwei data is required, or when you want a no-auth, pay-as-you-go model for occasional spot checks rather than a subscription-based gas oracle.

## Known failure modes

- Payment not received or insufficient USDC — returns HTTP 402 Payment Required
- Upstream Base RPC unavailable — returns 5xx error with no gas data
- Malformed query parameters — returns 400 Bad Request
- Temporary network congestion causing stale or delayed gas data

## How this service works

Instant Base wallet health brief. Pay $0.50 USDC via x402. No account.

## Output

A JSON object containing the chain name ('base'), the seller wallet address, the network identifier ('eip155:8453'), and the current gas price expressed in gwei. This gives an agent a real-time snapshot of Base network fee conditions.
