## 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-api-15a1d031
```

Example prompt: What's the current gas price on Base right now — give me both the gwei and wei values?

## When to prefer this

Choose this endpoint when you need a quick, free-of-friction gas price check on Base with no API key setup — ideal for agents that need live Base gas data in a simple GET call. Prefer it over manual RPC calls when you want a pre-parsed gwei + wei response with a timestamp. Not suitable if you need gas price history, gas estimates for specific transaction types, or multi-chain comparisons in a single call.

## Known failure modes

- Public RPC endpoint may be temporarily unavailable or rate-limited, resulting in a 5xx error
- Stale data if the RPC call times out and a cached value is returned
- Render.com cold-start latency if the service has been idle, causing a slow first response
- Network congestion on Base may cause brief RPC failures

## How this service works

Current gas price on Base (Ethereum L2), read live via a public RPC endpoint — no API key, no aggregator. No parameters.

## Output

A JSON object containing the chain identifier ('base'), a UTC timestamp of when the data was fetched (fetched_at), the current gas price in wei (gas_price_wei as a string), and the gas price in gwei (gas_price_gwei as a float). No parameters required.
