How this service works
Live whale alerts: the largest recent USDC / WETH / cbBTC / USDT / WBTC transfers on Base or Ethereum, with USD value, from/to wallets, counterparty labels (contract? verified? scam-flagged?), tx hash and age. The smart-money / whale-watching feed trading agents poll to front-run big flows — a Nansen-style whale alert without the subscription. Each whale wallet chains into /crypto/smart-money (what is this wallet doing?) and /crypto/wallet (what does it hold?).
Output
A JSON array of recent large token transfers, each including the USD value, sender and recipient wallet addresses with counterparty labels (contract, verified, or scam-flagged), the transaction hash, token symbol, and transfer age — ordered by transfer size descending.
Example use cases
Example prompt
“Show me the 20 biggest USDC transfers on Ethereum in the last hour, only ones over $50,000, and flag which wallets are contracts or scam-tagged.”
Technical details
Endpoint
GEThttps://store.agentexchange.work/crypto/whalesWhen to prefer
Choose this endpoint when you need real-time, ready-parsed whale transfer data with labeled counterparties (scam flags, contract status, verified tags) for Base or Ethereum without needing a Nansen or Whale Alert subscription. Prefer it over raw on-chain RPC calls when you want USD-denominated filtering, human-readable wallet labels, and a structured feed suitable for trading signal pipelines or portfolio monitoring agents.
Side effects
- Unsupported token symbol for the selected chain returns an error or empty result
- min_usd set too high returns an empty whale list if no transfers qualify
- Invalid chain value (not 'base' or 'ethereum') returns a validation error
- limit out of range (>50 or <1) returns a schema validation error
- Blockscout upstream outage causes 503 or timeout
- ERC-20 contract address that is not indexed returns no results
