## 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 apex-runner-whale-sentiment-signal-1c04e4d9
```

Example prompt: What's the current whale sentiment right now — are large crypto holders net long or short, and how strong is the conviction?

## When to prefer this

Use this endpoint when you need a quick, pre-aggregated read on large holder directional bias without building your own on-chain wallet tracking. Ideal for informing trading strategy decisions, confirming momentum signals, or filtering noise in volatile markets. Prefer this over raw on-chain data when you want a simple bullish/bearish/neutral verdict with a conviction qualifier.

## Known failure modes

- Payment failure (402): insufficient USDC balance or x402 payment not accepted
- Rate limiting if called too frequently
- Stale data if underlying whale tracking pipeline is delayed
- Network timeout on the signal aggregation backend
