## 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 synapse-api-hyperliquid-latest-block-803b7054 -d '<json body>'
```

Example prompt: What is the latest block on Hyperliquid right now? I need the current block number and timestamp.

## When to prefer this

Choose this endpoint when you specifically need real-time or near-real-time latest block data from the Hyperliquid blockchain and are already operating within the Synapse API pay-per-call x402 ecosystem. Prefer it over generic blockchain explorers when you need programmatic, low-latency access to the Hyperliquid chain tip without managing your own RPC infrastructure.

## Known failure modes

- Network timeout if Hyperliquid RPC node is unreachable
- 402 Payment Required if USDC payment is not attached or insufficient
- Empty or malformed response body if Hyperliquid chain is experiencing downtime
- Rate limiting if too many calls are made in quick succession
- Invalid request body schema returns 400 or similar error
