## 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 amanchain-whale-watch-fb82b63e -d '<json body>'
```

Example prompt: Who are the whale wallets holding the most of this token — can you check live on-chain and show me the largest holders and any big recent transfers?

## When to prefer this

Choose this endpoint when you need live, deterministic on-chain whale data without setting up an API key or account — ideal for agents that need pay-per-call access to real blockchain state for whale tracking, large holder analysis, or big transfer detection on Base. Prefer this over centralized analytics platforms when trustless, node-executed results are required.

## Known failure modes

- Invalid token or wallet address returns an error response
- Service unavailable if AmanChain node is out of sync
- Insufficient USDC balance causes x402 payment failure and no data returned
- Malformed JSON request body results in parsing error
- Rate limiting if the node is under heavy load

## How this service works

Whale Watch: node-operated on-chain service Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-whale-watch","request":"<input>"}. No account, no API key.

## Output

Returns on-chain whale data including large wallet addresses, their balances, recent large transfers, and token concentration metrics — sourced from live blockchain consensus state at the time of the call.
