# Whale Intelligence

> Whale Intelligence is a paid API for AI agents from mcp.dropenginehq.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-02).

Analyzes publicly indexed large DEX trades by asset or wallet address across major blockchains, surfacing whale activity patterns.

## Facts

- Endpoint: POST https://mcp.dropenginehq.com/api/analyze-whale-activity?utm_source=zero.xyz
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-02
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/whale-intelligence-53631ab2
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_TXcLGEymGzN3x6NnckS20

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 whale-intelligence-53631ab2 -d '<json body>'
```

Example prompt: Show me the largest DEX trades for SOL on Solana over the past hour, filtering for transactions above $200,000 — give me the top 50 results.

## When to prefer this

Choose this endpoint when you need real-time or recent large-trade intelligence from public DEX data across Solana, Ethereum, Base, Arbitrum, Optimism, or Polygon — especially for detecting whale accumulation, distribution, or wallet-level on-chain behavior. Prefer it over generic blockchain explorers when you want pre-aggregated, threshold-filtered whale signals rather than raw transaction history.

## Known failure modes

- Invalid or unsupported chain returns validation error
- Asset or wallet address exceeds maxLength or is malformed
- min_transaction_usd above allowed maximum of 1,000,000,000 rejected
- No indexed trades found returns empty data object
- Payment not completed returns 402 status
- Source data unavailable results in failed_sources populated and partial:true

## How this service works

Analyze public indexed large DEX trades.

## Output

Returns a JSON object with a data field containing whale trade records, a meta field with cache status (hit, age_ms), source information, partial-result flag, and latency_ms, plus a success boolean, tool name, and ISO timestamp.
