How this service works
Recent large ETH transfers with sender/receiver labels and entity classification. AI agent API for whale movement detection and flow analysis
Output
A list of recent large ETH on-chain transfers, each including sender and receiver wallet addresses with human-readable labels (e.g. 'Binance', 'Jump Trading'), entity type classification (exchange, fund, unknown, etc.), transfer amounts in ETH, and timestamps — enabling analysis of where large capital is flowing on Ethereum.
Example use cases
Monitor exchange inflows for trading signals
“Check the latest big ETH transfers coming into major exchanges — I want to know if whales are dumping or if smart money is accumulating right now.”
Track fund and protocol treasury movements
“Show me recent large ETH movements from known funds and protocol treasuries — I need to spot when major players are repositioning their holdings.”
Detect coordinated whale activity patterns
“Give me the biggest ETH transfers from the last few hours with labels so I can see if multiple whales are moving in the same direction at once.”
Technical details
Endpoint
GEThttps://whale.hugen.tokyo/whale/movementsWhen to prefer
Use this endpoint when you need real-time or near-real-time intelligence on large Ethereum transfers enriched with entity labels, especially for detecting smart money flows, exchange inflows/outflows, or coordinated whale activity. Prefer this over generic block explorers when you need pre-labeled sender/receiver classification rather than raw address data.
Side effects
- No large transfers detected in the recent window — returns empty list
- Rate limit or payment failure — 402 payment required if x402 header is missing or insufficient
- Service unavailable — upstream node indexer down, returns 503
- Stale data — if the indexer lags, returned transfers may not reflect the last few minutes
