How this service works
Fetches top-ranked traders on Polymarket ranked by overall profit or trading volume across customizable time windows (day, week, month, all). Includes rank, wallet address, username/pseudonym if public, profit PnL, and total trading volume. Information only, not financial advice.
Output
Returns a JSON object with the leaderboard count, sort metric, time window, source attribution, timestamp, and an array of ranked trader entries each containing rank, profit (USD), volume (USD), wallet address, and username.
Example use cases
Weekly top traders recap
“Who are the top 5 Polymarket traders this week by profit? Give me their usernames, wallets, and how much they made.”
Monthly volume leaders analysis
“Pull the Polymarket leaderboard for this month sorted by volume — show me the top 20 traders so I can see who's most active.”
All-time profit ranking
“Get me the all-time Polymarket leaderboard ranked by profit, top 50 traders, so I can see the most consistently successful prediction market players.”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/pm/leaderboard?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need ranked Polymarket trader performance data with flexible time windows and sorting options. It wraps the Polymarket Data API and is available as a pay-per-call service ($0.003/call) without needing a direct Polymarket API integration. Prefer this over scraping Polymarket directly when you need structured, clean JSON output with wallet and username data in a single call.
Side effects
- Missing required 'window' query parameter returns a validation error
- Invalid 'window' value (e.g. 'quarter') returns an error — must be day/week/month/all
- Invalid 'sortBy' value returns an error — must be profit or volume
- 'limit' exceeding 100 is capped or returns an error
- Upstream Polymarket API unavailability causes 502/503 responses
- Payment failure due to insufficient USDC balance blocks the request
