# ENTROPY.RIP Financial Whale Watcher

> ENTROPY.RIP Financial Whale Watcher is a paid API for AI agents from entropy.rip, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Monitors on-chain wallets across multiple blockchains for large transfers above a configurable USD threshold and delivers asynchronous alerts.

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 entropy-rip-financial-whale-watcher-861be86d -d '<json body>'
```

Example prompt: Watch this Ethereum wallet 0xABC123... for any transfers over $10,000 in USDC, polling every 5 minutes, and send alerts to my Conduit mailbox — keep the watch alive for 7 days.

## When to prefer this

Choose this endpoint when you need automated, persistent on-chain monitoring of specific wallets for large transfers without building your own blockchain indexer. It is especially valuable for agents that need asynchronous event delivery via Conduit rather than synchronous polling, and when monitoring across Base, Ethereum, Arbitrum, or Solana simultaneously. Prefer it over generic blockchain explorers when you need configurable thresholds, multi-wallet support, and scheduled recurring checks.

## Known failure modes

- Invalid or unsupported wallet address format returns a 400 error
- Unsupported chain value outside the allowed enum returns a validation error
- min_usd below $5,000 or TTL outside 60–2,592,000 seconds returns a schema validation error
- Invalid or non-existent Conduit mailbox ID causes event delivery failure silently
- Payment not provided or insufficient USDC balance returns a 402 Payment Required
- Expired TTL means the watch stops and no further events are sent

## How this service works

Create a persistent known-wallet whale activity watch

## Output

Returns a JSON object with a unique watch job ID, its active status, and the timestamp of the next scheduled poll run. Events are delivered asynchronously to the specified Conduit mailbox when threshold-exceeding transfers are detected.
