Output
Returns a JSON object containing the token address, chain, analysis period (24h), a list of large transfers detected, the net flow direction (e.g. 'neutral', 'inflow', 'outflow'), a whale activity score (numeric), total transfer count, and the timestamp of analysis. Token name and symbol may be null if not resolved.
Example use cases
Example prompt
“Check whale activity for USDC (contract 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913) on Base — are there any large transfers in the last 24 hours, and is the net flow bullish or bearish?”
Technical details
Endpoint
POSThttps://defi-shield-hazel.vercel.app/api/defi/whale-alertsWhen to prefer
Use this endpoint when you need a quick, scored summary of whale-level token movement on a specific chain within the last 24 hours, especially when you want to assess accumulation vs. distribution pressure or detect unusual large-wallet activity without running raw on-chain queries yourself.
Side effects
- Token address not found or invalid — returns empty large_transfers and zero counts
- Chain not supported — may return error or empty result
- No on-chain data available for the period — returns zeros and neutral direction
- Network timeout or RPC failure — response may be delayed or error returned
- Token has no whale-level activity in 24h — returns valid response with empty arrays and score of 0
