How this service works
Nansen blockchain analytics — 44 endpoints (smart money, profiler, TGM, perps, indicators)
Output
Returns a structured dataset of wallet addresses and their Nansen labels (e.g. 'Smart Money', 'DEX Trader', 'Fund') that have bought or sold the specified token, along with transaction details such as amounts and timing, sourced from Nansen's on-chain intelligence layer.
Example use cases
Detect institutional exit from emerging tokens
“Check which VC funds and institutional wallets have been dumping this new token over the past week. I need to know if the smart money is still holding or bailing out.”
Track whale accumulation patterns during dips
“Show me which whale and smart money wallets bought the dip on $SOL in the last 24 hours. I want to see if the big players are loading up or staying on the sidelines.”
Identify coordinated smart money movements
“Pull up all the Nansen-labeled smart money wallets that bought or sold $ETH in the last 48 hours. Help me understand if there's coordinated accumulation or if they're all taking profits at the same time.”
Technical details
Endpoint
POSThttps://api.vibe.airforce/api/x402/vibe-tools/data-provider/nansen/who-bought-soldWhen to prefer
Use this endpoint when you need to identify specific wallet identities (with Nansen labels) behind buying and selling activity for a token — especially for detecting smart money accumulation or distribution. Prefer over generic DEX trade data endpoints when wallet labeling and classification (e.g. 'Smart Money', 'VC Fund', 'DEX Trader') is required to interpret who is moving a token.
