How this service works
Get recent large cryptocurrency movements (whale alerts)
Output
Returns a list of recent large cryptocurrency transactions, each containing the sender address, receiver address, transaction type (e.g. exchange_deposit), token symbol, amount, and ISO 8601 timestamp.
Example use cases
Monitor whale exchange deposits
“Pull the latest whale alerts and tell me if any large holders are depositing massive amounts into exchanges — could be a signal someone is about to sell.”
Track large USDC outflows
“Check for any recent whale-sized USDC transfers and show me the sender and receiver addresses along with the amounts and timestamps.”
Market intelligence before trading
“I'm about to make a trade — can you quickly check if there are any recent whale movements that might signal big market activity I should know about?”
Technical details
Endpoint
GEThttps://x402.asterpay.io/v1/crypto/whale-alerts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time visibility into large on-chain cryptocurrency movements without building your own blockchain indexing infrastructure. It is ideal for trading bots, market intelligence dashboards, or DeFi risk monitors that need to react quickly to whale activity. Prefer this over general price feeds when the question is about who is moving funds rather than what price is doing.
Side effects
- No alerts available if no large transactions occurred recently
- Rate limiting or payment failure if USDC payment not properly attached
- Empty alerts array if whale threshold not met in recent window
- Malformed or unavailable response if upstream blockchain data source is down
