# ETH Whale Flow Monitor — Exchange Inflows & Outflows

> ETH Whale Flow Monitor — Exchange Inflows & Outflows is a paid API for AI agents from crypto-asistent.com, paid per call via x402, $0.04/call, status unknown (last checked 2026-10-13).

Returns large ETH transfers (>100 ETH) to and from known exchange wallets in the last 2 hours, flagging potential distribution pressure or accumulation signals.

## 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 eth-whale-flow-monitor-exchange-inflows-outflows-641f7e1d -d '<json body>'
```

Example prompt: Pull the latest whale ETH flows — I want to see any transfers over 100 ETH into or out of exchange wallets in the past 2 hours so I can gauge whether big holders are distributing or accumulating.

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call snapshot of large-volume ETH movements specifically between whale wallets and centralized exchanges, without needing to run your own node or maintain an address-labeling database. It is particularly useful for intra-day market context, pre-trade checks, or feeding signals into a trading or monitoring agent that polls periodically.

## Known failure modes

- No data returned if no transfers over 100 ETH occurred in the look-back window
- Stale data if the on-chain indexer lags behind the chain tip
- Misclassification of exchange wallets if the address label database is outdated
- Payment failure (402) if USDC balance is insufficient
- Internal server error if the upstream blockchain data provider is unavailable

## How this service works

Large ETH transfers (>100 ETH) to and from known exchange wallets in the last 2 hours. Inflows to exchanges are potential distribution pressure, outflows suggest accumulation or a move to cold storage — but read them as context, not instruction: a single large transfer is often internal rotation between wallets of the same desk.

## Output

A list of recent ETH transfers exceeding 100 ETH involving known exchange wallets, with each transfer tagged as an inflow (to exchange) or outflow (from exchange), including amounts, counterparty addresses, exchange names, and timestamps — enabling assessment of net whale positioning relative to centralized venues.
