How this service works
Pay-per-call market intelligence for AI agents across crypto, US and European stocks, rates and FX: on-chain buy/sell pressure, trading decisions from $0.05, token risk checks on six chains, webhook alerts, pre-trade verdicts, technicals, perps funding, smart money, SEC and ESEF fundamentals, insider trades, European short interest, ECB rates and FX, datasets and news.
Output
Returns a JSON object with the symbol's mark price, smart money net flow in USD over the last 2 days, directional bias (NET_BUYING or NET_SELLING), total wallets tracked and ranked, and a list of top wallets with their total PnL, realized PnL, win rate percentage, number of closed positions, current open position size in USD, and average holding time in minutes.
Example use cases
Pre-trade smart money check for ETH
“Before I buy Ethereum, can you check what smart money wallets are doing with ETHUSD — are they net buying or selling over the last couple of days, and what do the top wallets look like by PnL?”
Whale activity scan for tokenized NVDA
“I'm thinking of trading NVDA — can you pull the smart money flow data for it and tell me if on-chain wallets are accumulating or distributing, and which wallets have the highest win rates?”
On-chain sentiment check for BTCUSD
“What's the smart money bias on BTCUSD right now? I want to know the net flow in USD from smart wallets over the past two days and see the top wallet performers ranked by realized PnL.”
Technical details
Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/intelligence/smart-money/%7Bsymbol%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain smart wallet intelligence for a specific crypto or tokenized US equity — particularly to assess directional bias (net buying vs selling) and top-wallet PnL rankings before making a trading decision. Prefer this over generic price feeds or news sentiment endpoints when you want to understand what informed, high-performing wallets are actually doing rather than what analysts are saying.
Side effects
- Unknown or unsupported symbol returns an error or empty result
- Payment failure (402) if x402 USDC micropayment is not properly attached
- Rate limiting if too many calls are made in short succession
- Stale or missing data if the symbol has low on-chain activity
- Network timeout for real-time data fetch under high load
