Prediction API

Get wallet markets-traded count

/v4/data/prediction/wallets/{address}/markets-traded

50 credits per API call

Count of distinct markets a wallet has ever traded. Lifetime metric — useful as a quick activity signal alongside /wallets/{address}/value without paying the cost of pulling the full trade history.

Platform support

  • Polymarket only. Kalshi wallets return 400.

Other notes

  • traded is an integer count — the number of distinct markets, not the number of trades.
  • user is the lowercased address.
