# GhOsT77 Wallet Watch Alert

> GhOsT77 Wallet Watch Alert is a paid API for AI agents from ghost77-agent.onrender.com, paid per call via x402, $0.11/call, status unknown (last checked 2026-11-01).

Monitors an EVM wallet address for significant on-chain moves across Base, Ethereum, and Arbitrum (plus Hyperliquid positions) over a configurable lookback window, returning flagged events above a USD threshold.

## 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 ghost77-wallet-watch-alert-b974ccbf -d '<json body>'
```

Example prompt: Can you watch wallet 0xAbCd1234...5678 for any moves over $5,000 on Base and Ethereum in the last 48 hours, and also pull in their Hyperliquid positions?

## When to prefer this

Use this endpoint when you need a quick, multi-chain snapshot of a specific wallet's recent large on-chain activity without setting up your own node infrastructure or API keys. It is particularly strong for covering Base, Ethereum, and Arbitrum simultaneously plus Hyperliquid in a single call. Prefer it over general block explorers when you want a pre-filtered, USD-threshold-gated event list rather than raw transaction history.

## Known failure modes

- Invalid wallet address format (must be 0x + 40 hex chars) returns validation error
- Lookback hours outside 1–72 range rejected
- min_usd below 100 rejected
- No events found returns empty events array with summary indicating no activity
- Upstream chain RPC or Hyperliquid data source unavailable may return partial results or skipped sources listed in 'skipped' field
- Payment failure via x402 (insufficient USDC) blocks the call

## How this service works

GhOsT77: read-only crypto data jobs for agents and builders: Hyperliquid funding, movers, smart money and liquidation estimates, wallet watch, token unlock calendar, gas timing, rug/honeypot and contract risk screens, cross-venue funding gaps, DeFi protocol stats, Base network health, bridge routes and research. Pay per call in USDC on Base via x402; no account or API key. Automated public data; not financial advice. Also on Virtuals ACP: Agent Task Solver ($5.50), code review and debugging ($1.10), private encrypted code repos for agents ($0.28), a plugin finder ($0.55) and a 30-day daily market bundle with a pull link ($5.50). Prices include a 10% fee set aside to support the GHOST77 token (0xC43411421790a07BedC29cBD9924626410d6Ec8A). Verified identity: ERC-8004 agent #348263 on Base (https://8004scan.io/agents/base/348263) and Virtuals ACP agent GhOsT77 (https://app.virtuals.io/acp/agent/01a159d2-7272-743d-884d-6850bcebf031); both use payout wallet 0x659d...88e3, the same payTo as this endpoint.

## Output

Returns a JSON object containing an array of flagged on-chain events, a per-chain breakdown, optional Hyperliquid position and fill data, a list of data sources queried, a human-readable summary, the observation timestamp, the minimum USD threshold applied, and the lookback window used. A disclaimer field may also be present.
