# AmanChain Whale Watch

> AmanChain Whale Watch is a paid API for AI agents from amanchain-relay.gitajhd.workers.dev, paid per call via x402, $0.012441/call, status unknown (last checked 2026-09-13).

Monitors and identifies large on-chain wallet movements (whale activity) against live blockchain consensus state, paid per call via x402 in USDC.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-03dc3a86 -d '<json body>'
```

Example prompt: Check for whale activity on the USDC token contract right now — show me any large wallet movements happening on Base against the live chain state.

## When to prefer this

Choose this endpoint when you need real-time, node-executed whale tracking directly against live blockchain consensus state on Base, without requiring an API key or account — especially when paying per-call via x402 in USDC and needing deterministic, trustless execution rather than aggregated third-party data.

## Known failure modes

- Malformed or missing request string returns an error response
- Invalid token or wallet address results in no data or an error
- Network congestion or node sync lag may cause stale data
- Payment failure via x402 (insufficient USDC balance) blocks the call
- Unsupported chain or token contract may return empty results

## How this service works

Whale watch — large on-chain transfers above any threshold you set; real-time whale alert feed for AmanChain. Deterministic on-chain execution by the AmanChain node — live consensus state, real blocks, pools and balances. Pay per call via x402 (USDC on Base), no account, no API key. POST JSON {"serviceId":"aman-whale-watch","request":"<input>"}.

## Output

Returns on-chain whale activity data sourced from live consensus state, including large wallet addresses, significant token movement amounts, transaction details, and holder balances — all executed deterministically against real blocks by the AmanChain node.
