## 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 crypto-market-data-whale-orders-0347e981
```

Example prompt: Show me the 10 biggest whale orders from the last hour across Binance and Hyperliquid for BTC — I want to see what side they were on and what the Hyperliquid trades did to positioning.

## When to prefer this

Choose this endpoint when you need to track large, potentially market-moving orders (whale trades) across both centralized (Binance) and decentralized (Hyperliquid) venues in a single call. It is the best option when you need Hyperliquid-specific position context (what the large trade actually did: opened, added to, or closed a position). Prefer it over generic price endpoints when the user's intent is order flow analysis, whale watching, or detecting institutional activity.

## Known failure modes

- Invalid token ticker returns empty orders array or error
- Limit outside 1-200 range returns validation error
- Payment failure (402) if x402 micropayment not provided
- Stale data if upstream Binance or Hyperliquid feeds are delayed (data_age_s will be elevated)
- Rate limiting if called too frequently without valid payment

## How this service works

The biggest market orders of the last hour on Binance futures, Binance spot and Hyperliquid, with what each Hyperliquid order did.

## Output

Returns a JSON object with an array of the largest orders in the last hour, each including USD size, BUY/SELL side, timestamp, price, token, venue (binance_futures, binance_spot, hyperliquid), how many times above normal minute volume the order was (x_normal_minute), and for Hyperliquid orders what the trade did (e.g. 'added to SHORT', 'closed SHORT'). Also includes a plain-language summary sentence, data freshness age in seconds, the 60-minute window, a snapshot seal, and a note that data refreshes every minute.
