How this service works
Get Arkham Polymarket leaderboard. $2.00 per call.
Output
A JSON object containing a sorted array of leaderboard entries, each with: rank, wallet address, period PnL (in USD), tokens won, total tokens, trade count, and an array of market category tags with label, event count, and volume for each category.
Example use cases
Identify top prediction market traders
“Who are the top 10 wallets making the most money on Polymarket today? Show me their PnL, how many trades they made, and what categories they're focused on — sorted from highest to lowest profit.”
Research profitable Polymarket strategies by category
“Pull the Polymarket leaderboard for the past day and tell me which market categories — like politics, sports, or crypto — the top-ranked traders are concentrating their volume in.”
Monitor whale activity on Polymarket
“I want to track the highest-earning Polymarket wallet addresses over the last 24 hours. Give me their ranks, total PnL, and trade counts so I can watch for patterns in how they're positioning.”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/polymarket/leaderboardWhen to prefer
Use this endpoint when you need ranked, on-chain Polymarket trader performance data enriched with wallet intelligence from Arkham — especially when you want PnL-sorted leaderboards with category breakdowns. Prefer this over raw on-chain queries when you need pre-aggregated stats across multiple market tags without building your own indexer.
Side effects
- Invalid or missing sort/period parameters return an error response
- x402 payment failure if USDC balance is insufficient (endpoint requires $2 USDC per call)
- Empty leaderboard if no trading activity occurred in the specified period
- Rate limiting or authentication errors if API key is invalid
- Network timeout if Arkham backend is under load
