## 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 agentstoolshub-gas-price-c6e742c8
```

Example prompt: What's the current gas price on Ethereum right now in gwei and USD — ETH is trading at $3,200?

## When to prefer this

Use this endpoint when you need a real-time, on-chain gas price without managing your own RPC infrastructure or API keys, and you want a ready-made USD cost estimate for a standard 21,000-gas transfer alongside the raw gwei figure. Ideal for agents that need quick gas checks on Base or Ethereum mainnet before deciding whether to execute a transaction.

## Known failure modes

- RPC node unavailable or rate-limited — upstream connection error
- Invalid or missing ethPriceUsd parameter — request fails validation
- Unsupported chain value supplied — rejected by enum constraint
- Network congestion may cause stale or delayed gas price readings
- Payment of 0.002 USDC not completed — 402 response blocking access

## How this service works

Fetch the live gas price from public RPC nodes on Base or Ethereum: wei per unit gas, converted to gwei, with a USD estimate for a standard 21,000-gas transfer using your own ETH price input. No API key needed. Use this when an agent needs to current gas price in gwei and USD, straight from the chain.

## Output

Returns the current gas price fetched directly from public RPC nodes: the raw value in wei, the converted value in gwei, and a USD cost estimate for a standard 21,000-gas transfer computed using the caller-supplied ETH/USD price. No API key required.
