## 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-newcomer-whale-detection-03675189 -d '<json body>'
```

Example prompt: Show me the newcomer whales on Hyperliquid right now — wallets that have appeared recently but are already trading large sizes in perps.

## When to prefer this

Use this endpoint when you specifically want to identify traders who are new to Hyperliquid but are already deploying large capital in perpetuals — useful for copy-trading research, market surveillance, or monitoring emerging market participants. Prefer this over general leaderboard endpoints when you need to filter for recency of account activity combined with position size.

## Known failure modes

- HTTP 402 if free quota exceeded — requires x402 USDC micropayment to proceed
- Empty result set if no newcomer whales detected in the requested time window
- Timeout or 503 if the underlying Hyperliquid node fill ledger is temporarily unavailable
- 400 Bad Request if required body fields are missing or malformed
- Stale data if the node fill ledger indexing lags behind real-time chain state

## How this service works

Operator-neutral Hyperliquid trading intelligence — perp fills, position lifecycles, all-wallet leaderboards, trader cohorts, liquidation risk and prediction markets. Every endpoint is FIRST-PARTY: computed from our own node_fills ledger and the Hyperliquid public info API (no third-party data source). Free quota, then HTTP 402 (x402: pay-per-call in USDC, no account, no key).

## Output

Returns a ranked list of newly emerged large-position traders on Hyperliquid, including wallet addresses, position sizes, fill counts, estimated PnL, account age, and cohort labels identifying them as newcomer whales based on first-party node fill ledger data.
