## 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 100btc-blockchain-essentials-api-5cc6667f -d '<json body>'
```

Example prompt: Can you check the current gas fees, ETH and BTC prices, sequencer health, and block height on the Ethereum network right now?

## When to prefer this

Use this endpoint when you need a single low-cost call to retrieve a comprehensive snapshot of a blockchain network's current state — gas fees, crypto rates, sequencer health, and block height — in one shot, rather than querying multiple separate oracle or RPC endpoints.

## Known failure modes

- Unsupported or invalid chain identifier returns an error or empty response
- Network outage on the target chain may return stale or unavailable data
- Payment failure (402) if USDC micropayment is not properly attached
- Sequencer or RPC node downtime may cause partial data responses
