## 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-ab325ee5
```

Example prompt: Pull a whale dossier on wallet address 7xKp...ABcd on Solana — I want to see their holdings, recent trading behavior, and what tokens they've been accumulating.

## When to prefer this

Choose this endpoint when you need a structured, pre-built intelligence profile on a known large wallet address on Solana or Base, rather than manually querying raw blockchain data. It is especially useful when you want aggregated behavioral signals and portfolio composition in a single call at a low per-query cost ($0.59 USDC).

## Known failure modes

- Invalid or unrecognized wallet address returns an error or empty dossier
- Wallet with no significant activity may return sparse results
- Chain not supported for given address format causes a 400-level error
- Payment failure via x402 protocol blocks the request before execution
- Rate limiting or quota exhaustion returns a 429 error
- Malformed properties parameter returns schema validation error

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana and Algorand via x402.

## Output

A JSON dossier containing the whale wallet's profile, including token holdings, portfolio value, recent transaction patterns, trading history, and behavioral signals derived from on-chain data across Solana and/or Base networks.
