## 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 ai-rook-gas-tracker-6d8e342e
```

Example prompt: What are the current gas prices on Base mainnet right now — give me the base fee and priority fee so I can decide whether to submit my transaction.

## When to prefer this

Choose this endpoint when an agent needs real-time gas price data on Base mainnet before executing or timing an on-chain transaction, especially within an agentic workflow already using x402 micropayments and USDC on Base. Useful as a pre-flight check before any DeFi action or smart contract call.

## Known failure modes

- Network RPC unavailable — upstream node unreachable, returns 5xx error
- Payment insufficient — $0.002 USDC x402 payment not included or rejected
- Rate limiting — too many requests from same wallet
- Stale data — gas data may lag a few seconds during network congestion

## How this service works

Current Base mainnet gas prices. Slow, standard, fast in gwei.

## Output

Returns current gas price metrics including base fee, priority fee (tip), and estimated gas costs for transactions on the Base (or Ethereum) network, helping agents decide optimal timing for on-chain actions.
