How this service works
Get whale movement data — Solana: 12 tracked whale wallets (Wintermute, Kraken, etc.) with SOL moved, exchange inflow/outflow, and largest transactions. BTC: mempool fee trends, congestion levels, hashrate, and block data. Last 24 snapshots. AI agent API for smart money tracking, whale alert monitoring, and on-chain flow analysis.
Output
Returns up to 24 timestamped snapshots of on-chain whale activity. For Solana: data on 12 tracked whale wallets (including Wintermute, Kraken) covering SOL moved, exchange inflow/outflow amounts, and largest individual transactions. For Bitcoin: mempool fee trends, network congestion levels, current hashrate, and recent block data.
Example use cases
Monitor whale accumulation before market moves
“Check the Bitcoin mempool fees and hashrate right now — I need to see if whales are moving large amounts to exchanges or accumulating off-exchange. Give me the last 24 snapshots of big transactions and network congestion so I can spot unusual activity.”
Track institutional Solana wallet flows daily
“Pull the latest data on what Kraken, Wintermute, and the other major Solana wallets have been moving in the past day. I want to know their exchange inflows and outflows — are they accumulating SOL or sending it to trading venues?”
Detect Bitcoin fee spikes and network stress
“Show me the Bitcoin mempool trends over the last 24 hours — what are the current fee levels, congestion, and block data telling us? Also include any large whale transactions so I can see if smart money is moving during high-fee periods.”

Endpoint
GEThttps://api.carbon-cashmere.de/v1/whale-flow/:chainWhen to prefer
Use this endpoint when you need real-time smart money tracking and whale wallet flow data for Solana or Bitcoin specifically, with exchange inflow/outflow breakdowns and named institutional wallets. Prefer this over generic price APIs when the intent is to understand large-holder behavior, detect exchange-bound movements, or assess Bitcoin network congestion and mempool fee dynamics.
