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 forgemesh-whale-alerts-d500a178
```

Example prompt: Pull the latest whale alerts on Ethereum for the past 24 hours — I want to see any big wallet moves, CEX flows, bridge activity, and stablecoin mints or burns.

## When to prefer this

Use this endpoint when you need a quick snapshot of significant on-chain activity — whale wallet moves, large exchange flows, cross-chain bridge transfers, or stablecoin supply changes — across Ethereum, Base, or Arbitrum within a recent time window. Prefer it over generic block explorers when you want pre-filtered, anomaly-focused alerts rather than raw transaction data.

## Known failure modes

- Invalid chain value (not ethereum, base, or arbitrum) returns an error
- Invalid hours value (not 1, 4, or 24) returns an error or falls back to default
- No alerts found in the window returns an empty alerts array with alert_count of 0
- Payment failure or missing x402 payment header returns 402 Payment Required
- Upstream data source lag may cause slightly stale results

## How this service works

Returns a list of recent whale transfers, CEX inflows/outflows, bridge moves, and stablecoin mint/burn events with amounts and timestamps — monitor large holder activity in real time.

## Output

Returns a JSON object containing the chain name, the lookback window in hours, a count of alerts, and an array of alert objects describing individual large-wallet movements, CEX inflows/outflows, bridge transfers, and stablecoin mint/burn events detected in the requested time window.
