Quick way to check if a token's holder base is serious money or just retail gamblers. You get smart money holder ratios, flow breakdowns by wallet label (funds, whales, fresh wallets), and recent buyer quality data straight from Nansen. The flow intelligence endpoint is especially useful here. High fresh wallet inflows plus low smart money holders is your classic red flag. Works across major chains but note that it doesn't support native or wrapped tokens, so you need the actual token contract address. Requires a Nansen API key, which isn't cheap, but if you're already paying for it this beats clicking through their dashboard.
