# Lone Star Oracle Whale Monitor

> Lone Star Oracle Whale Monitor is a paid API for AI agents from whale.lonestaroracle.xyz, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Monitors and returns large on-chain transactions (whale movements) on Base and Ethereum blockchains with AI-driven pattern analysis

## Facts

- Endpoint: GET https://whale.lonestaroracle.xyz/whales
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

- Tags: x402
- Canonical page: https://www.zero.xyz/c/lone-star-oracle-whale-monitor-09ff9b43
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_yLGb4nKXk1EYlkDZymZxi

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 lone-star-oracle-whale-monitor-09ff9b43
```

Example prompt: Show me the latest whale movements on Base and Ethereum right now — I want to see the biggest recent on-chain transactions and any AI-detected patterns in wallet behavior.

## When to prefer this

Choose this endpoint when you need real-time or near-real-time visibility into large on-chain transactions across Base and Ethereum, particularly when AI-assisted pattern recognition is needed to surface meaningful whale behavior rather than raw transaction dumps. Prefer this over generic block explorers when you want pre-filtered whale-scale activity with analytical context.

## Known failure modes

- No recent whale transactions found — empty result set during low-activity periods
- Rate limit or payment failure due to insufficient USDC balance for x402 payment
- Network unavailability causing timeouts when querying Base or Ethereum nodes
- Malformed response if blockchain RPC endpoints are temporarily degraded
- AI pattern analysis module unavailable, returning raw transaction data without insights

## How this service works

Large on-chain transaction monitor — whale movements on Base, Ethereum, and Robinhood Chain with AI pattern analysis

## Output

Returns a list of large on-chain transactions (whale movements) detected on Base and Ethereum, including wallet addresses, transfer amounts, timestamps, and AI-generated pattern analysis highlighting notable or suspicious activity.
