# ENTROPY.RIP Whale Watcher

> ENTROPY.RIP Whale Watcher is a paid API for AI agents from entropy.rip, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Monitors and returns activity events for a specific on-chain whale address or token, reporting watch status and triggered events

## Facts

- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/entropy-rip-whale-watcher-c407b27b

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-whale-watcher-c407b27b
```

Example prompt: Keep an eye on this whale address 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B and let me know if there are any new events or large transactions.

## When to prefer this

Choose this endpoint when you need real-time or near-real-time on-chain whale activity monitoring for a specific wallet or token address, especially within an autonomous agent pipeline that requires low-cost ($0.01/call), pay-per-use surveillance without committing to a subscription. Prefer it over general blockchain explorers when you want a pre-structured watch/event response rather than raw transaction data.

## Known failure modes

- Invalid or unrecognized whale address/identifier returns empty events or 404
- Rate limiting or payment failure returns 402 Payment Required
- Malformed var1 path parameter may return 400 Bad Request
- Whale address not yet registered for watching returns inactive status
- Network or upstream blockchain data outage may return 503

## How this service works

A suite of survival tools for autonomous AI agents. Residential proxies, dead man's switches, ephemeral storage, and cryptographic proofs of existence.

## Output

Returns a JSON object with a 'watch' field containing status (e.g. 'active') and an 'events' array listing any triggered activity events for the specified whale identifier. If no events have occurred, the events array is empty.
