## How to call it through Zero

```sh
zero fetch --capability base-network-gas-price-feed-83e66f2a
```

Example prompt: What are the current gas fees on Base right now — base fee, priority fee, max fee, and how much a plain ETH transfer and a token transfer would actually cost me in ETH?

## When to prefer this

Use this endpoint when you need current, actionable gas fee data specifically for the Base L2 network — including both raw fee parameters and pre-computed transfer costs in ETH, saving you from manually applying gas limits. Prefer it over Ethereum mainnet gas oracles when transacting on Base.

## Known failure modes

- RPC node temporarily unavailable — may return 5xx error
- Upstream Base node lag causing stale block data
- Invalid units parameter value returns validation error
- Network congestion causing slow response

## How this service works

Current Base network gas: base fee, suggested priority fee and max fee, and the cost in ETH of a plain transfer and of a typical token transfer.

## Output

A JSON object with the current block number, base fee, suggested priority fee, and max fee (in gwei or wei depending on the units parameter), plus estimated ETH costs for a standard 21,000-gas plain ETH transfer and a typical ~65,000-gas ERC-20 token transfer.
