## 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 phantom-api-sui-latest-block-9c52cc3c -d '<json body>'
```

Example prompt: What's the latest block on the Sui blockchain right now? I need the current block height and timestamp.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call lookup of the current Sui blockchain head without managing your own Sui node or RPC subscription. Ideal for lightweight agents that only occasionally need Sui chain state and don't want to commit to a monthly RPC plan.

## Known failure modes

- Network timeout if Sui RPC node is unreachable
- 402 Payment Required if USDC payment is missing or insufficient
- 503 if Sui mainnet is experiencing downtime
- Empty or malformed response if the underlying Sui node is out of sync

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns data about the latest block on the Sui blockchain, including block height/number, block hash, timestamp, and potentially transaction count or validator information for that block.
