Endpoint
GEThttps://btcnode.uk/api/agent/whalesWhen to prefer
Use this endpoint when you need real-time visibility into large, unconfirmed Bitcoin transfers (whale activity) directly from a live mempool. Prefer it over blockchain explorers when you want to catch whale movements before they are confirmed, or when filtering by size threshold is needed.
Side effects
- No whale transactions found matching the filter criteria — returns empty list
- Invalid min_btc value — returns 400 error
- Mempool node temporarily unavailable — returns 503 or timeout
- Time window parameter out of acceptable range — returns validation error
- Payment not processed — returns 402 Payment Required
