## 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 losbeto-whale-dossier-b0f08cdf
```

Example prompt: Pull up a full whale dossier for this Solana wallet — I want to see their holdings, recent trades, and any risk signals that stand out.

## When to prefer this

Use this endpoint when you need deep, aggregated intelligence on a specific large crypto wallet (whale) — especially when you need holdings, trading behavior, and risk profile in a single call. Prefer this over generic block explorers when you want pre-processed, AI-ready whale analytics rather than raw transaction data.

## Known failure modes

- Invalid or unrecognized wallet address returns error or empty profile
- Wallet with no significant on-chain activity may return sparse dossier
- Missing required properties parameter may cause malformed request
- Network congestion or RPC timeouts may delay data freshness
- Payment failure via x402 protocol blocks access with 402 response
