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 a JSON object with a chain identifier, a summary object, and an array of up to 24 time-ordered snapshots. For Solana: SOL moved per tracked whale wallet (Wintermute, Kraken, etc.), exchange inflow/outflow volumes, and largest individual transactions. For BTC: mempool fee trends, congestion level, hashrate, and block data.
Example use cases
Alert on Bitcoin exchange inflows spike
“Check the last 24 hours of Bitcoin mempool and exchange inflow data — I need to know if we're seeing a sudden surge in large holders moving coins to exchanges, and what the current fee trends look like.”
Track Solana whale repositioning signals
“Give me the recent Solana whale activity snapshots, especially focusing on whether Wintermute and Kraken have been accumulating or dumping, and show me the biggest single transactions from tracked wallets.”
Monitor Bitcoin mining pressure and fees
“Pull the last day of Bitcoin hashrate, block data, and mempool congestion — I want to understand if mining difficulty is shifting and whether fees are getting cheaper or more expensive right now.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/whale-flow/:var1When to prefer
Use this endpoint when you need smart-money whale wallet tracking with exchange inflow/outflow context for Solana or Bitcoin. It is uniquely valuable because it tracks named institutional wallets (Wintermute, Kraken) on Solana and provides BTC mempool fee and congestion data alongside hashrate — all in one structured time-series response. Prefer this over generic price APIs when on-chain flow signals are needed for trading intelligence or alert systems.
