## 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 hyperliquid-smart-money-whale-events-cursor-api-d88e5017
```

Example prompt: Check for any new Hyperliquid whale events since my last poll and give me only what's changed — use the cursor from the previous response so we don't re-fetch everything.

## When to prefer this

Choose this endpoint when you are polling Hyperliquid whale data on a schedule and want to minimize bandwidth and cost by receiving only new events since your last call. It is ideal for agents that run on a timer and must avoid redundant baseline reloads. Prefer sibling endpoints for full snapshots, market-wide overviews, or liquidation level lookups.

## Known failure modes

- Invalid or expired cursor returns error or full dataset reset
- No new events since last cursor returns empty result set
- Rate limiting if polling too aggressively
- Service unavailability returns HTTP 5xx
- Missing cursor parameter may return unexpected results

## How this service works

Only what changed since your last call: pass the cursor you got back and receive just the new whale events, never the whole base again. Built for agents that poll on a schedule and pay per request

## Output

A delta payload containing only whale events that occurred after the provided cursor position — new smart money activity on Hyperliquid perp markets — plus an updated cursor value to use on the next poll. No repeated baseline data is returned.
