Smart Money API — follow
the wallets that win

What is Smart Money?

"Smart Money" describes wallets that are consistently right: traders who enter early, exit well and stay profitable across market cycles. Following them is one of the oldest edges in on-chain trading — the hard part is knowing which wallets qualify.

CabalSpy labels a wallet as Smart Money when it belongs to a high-skill trader identified by historical win rate, ROI consistency and edge across multiple market cycles. The Smart Money API exposes that list — 440+ wallets — together with every trade those wallets make.

Smart Money vs KOL wallets

Both categories share the same endpoints, streams and response schema, so you can show them side by side — for example as two columns in a holders tab. Need influencer wallets? See the KOL API.

What the Smart Money API provides

• Wallet list — every tracked Smart Money wallet per chain with name, avatar, socials and copytrade link.
• Leaderboard — Smart Money wallets ranked by PnL, win rate, trades or volume for 6 hours, 1 day, 7 days or 30 days.
• Wallet profiles — realized PnL, win rate, traded tokens, live holdings, lifetime history and a PnL calendar per wallet.
• Token view — which Smart Money wallets hold a token, their position and their buys and sells.
• Signals — alerts when a cluster of Smart Money wallets buys the same token within a time window.
• Real-time streams — every Smart Money buy and sell pushed over WebSocket the moment it happens.

Quick start

Get a free key from the API dashboard, then list every Smart Money wallet on Solana:

curl "https://api.cabalspy.xyz/v1/wallets?blockchain=solana&type=smart&limit=50" \
  -H "Authorization: Bearer YOUR_KEY"

Rank them by performance over the last 7 days:

const p = new URLSearchParams({
  blockchain: "solana", type: "smart", period: "7d", limit: "20", api_key: "YOUR_KEY",
});
const res = await fetch(`https://api.cabalspy.xyz/v1/wallets/leaderboard?${p}`);
const { data } = await res.json();
data.leaderboard.forEach((w, i) =>
  console.log(`${i + 1}. ${w.profile.name || w.wallet} vol ${w.period_stats.total_volume}`));

Stream every Smart Money trade in real time:

const ws = new WebSocket("wss://stream.cabalspy.xyz?apiKey=YOUR_KEY");

ws.onopen = () => {
  // every Smart Money buy and sell on Solana, live
  ws.send(JSON.stringify({
    op: "subscribe", stream: "tx", blockchain: "solana", type: "smart", token: "*",
  }));
};

ws.onmessage = (e) => {
  const msg = JSON.parse(e.data);
  console.log(msg.event, msg.data);
};

Chains and coverage

Ethereum currently has KOL wallets only. On Solana, the same API also covers Whale wallets (type=whale).

What teams build with it

• Trading terminals — a Smart Money column in the holders table and buy/sell markers on the chart
• Copy-trading apps — a leaderboard of proven wallets to follow
• Alert and alpha bots — signals when Smart Money clusters into a token
• AI trading agents — check whether a wallet is tracked Smart Money before weighting its trade
