## 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-51fe5d0a
```

Example prompt: Pull the whale dossier for wallet address 9xQe...Kf3 on Solana — I want to see their full holdings profile and recent on-chain activity.

## When to prefer this

Choose this endpoint when you need a consolidated, ready-made intelligence report on a known large wallet holder on Solana or Base. It is preferable over raw blockchain explorers when you want pre-processed whale profiling without writing custom on-chain queries. Best suited for DeFi trading agents, risk assessment workflows, or market intelligence pipelines that need fast whale context for a specific address.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Wallet not classified as a whale may return minimal data or a 404-style response
- Network unavailability or payment failure results in no data returned
- Unsupported chain or properties filter may return a validation error
- Stale data if the dossier is cached and not real-time
