## 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 x402-chain-intel-ethereum-gas-price-feed-e179c63d -d '<json body>'
```

Example prompt: What are the current Ethereum gas prices right now — give me the base fee, priority fee, and recommended max fee per gas so I can decide whether to submit my trade?

## When to prefer this

Choose this endpoint when you need real-time Ethereum gas fee data for trading bots, DeFi automation, or transaction timing decisions and are already operating within an x402 micropayment workflow. It is well-suited for latency-sensitive trading infrastructure where per-call pricing ($0.05 USDC) is acceptable and you need granular EIP-1559 fee parameters rather than a simple gas oracle estimate.

## Known failure modes

- Ethereum node connectivity issues may return stale or unavailable data
- Payment failure via x402 protocol results in 402 Payment Required with no gas data returned
- Invalid or missing request body returns 400 Bad Request
- Service downtime on Vercel hosting returns 503
- Rate limiting if micropayment not confirmed in time
