## 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 vault-4-ai-fund-of-vaults-on-hyperliquid-db8539b0
```

Example prompt: Pull the latest VAULT-4 strategy snapshot — I want to see which Hyperliquid vaults the AI is top-picking right now, how it's allocating with the barbell strategy, and what the current market sentiment looks like. Use fresh live data, not the cache.

## When to prefer this

Use this endpoint when you need AI-curated, risk-adjusted vault selection and portfolio allocation intelligence specifically on Hyperliquid, rather than raw vault data or manual screening. Prefer this over generic DeFi dashboards when you want a pre-computed barbell allocation strategy informed by PnL history and market regime detection, updated on a 48-hour rebalancing cycle.

## Known failure modes

- Stale data returned if cache is not bypassed and upstream vaults haven't updated
- Upstream Hyperliquid API unavailable causing empty or partial candidate list
- Payment not processed (x402 payment required at $0.05 USDC per call)
- Rate limiting or cold-start latency on cloud run instance
- Claude AI ranking unavailable causing topPicks to be empty or null
