## 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 robinhood-chain-network-health-monitor-90d4cfb5
```

Example prompt: What are the current network stats for Robinhood Chain — I want to know the latest block, average block time, gas prices, and how many transactions have happened today.

## When to prefer this

Use this endpoint when you need a real-time, all-in-one snapshot of Robinhood Chain (an Arbitrum-based Ethereum L2) network health — especially gas prices, block cadence, transaction volume, and ETH price — without having to query an RPC node directly. Ideal for dashboards, alerts, or agents that need a single call to assess whether Robinhood Chain is operating normally.

## Known failure modes

- Upstream RPC node unavailability may cause stale or missing block/transaction data
- ETH price feed may be delayed or unavailable if price oracle is down
- Network congestion on Arbitrum L2 may cause slow or failed data retrieval
- HTTP 500 if internal Vercel function encounters an error
- Payment failure (402) if x402 USDC payment is not processed correctly
