## 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

```

Example prompt: Can you check for whale entry signals on ETH right now — I want to know if any large holders are accumulating or opening big positions on-chain?

## When to prefer this

Use this endpoint when you need on-chain whale entry detection specifically — i.e., identifying when large holders are accumulating or opening positions in a crypto asset. Prefer this over generic price feeds or volume APIs when you want behavioral signals from large wallets rather than raw market data. It is especially valuable for DeFi trading strategies, smart money tracking, or building alerts around institutional-scale on-chain activity.

## Known failure modes

- Unrecognized or unlisted token/asset symbol returns an empty or error response
- Insufficient on-chain data for low-liquidity tokens may yield no signals
- Invalid blockchain network parameter causes a 400-level error
- Payment failure via x402 protocol prevents endpoint execution
- Rate limiting or quota exhaustion returns an error after repeated calls
- Very recent token launches may have no historical whale data
