How this service works
Polymarket trader scorecard for any wallet: skill score (0-100), edge over the odds paid, win rate vs. the win rate the odds implied, return (ROI), realized PnL, specialty and largest open positions. Scores the latest 200 finished bets, losses included.
Output
A structured scorecard for the queried Polymarket wallet covering: skill score (0-100), edge over the odds paid (indicating whether the trader systematically picks underpriced outcomes), win rate versus the win rate implied by the odds, ROI percentage, realized PnL in USD, trading specialty (the market categories where the wallet outperforms), and a list of the wallet's largest current open positions. Based on the most recent 200 completed bets, losses included.
Example use cases
Vetting a prediction market tipster
“Someone's been sharing their Polymarket picks in a Discord and claiming they have an edge. Can you look up their wallet 0xAbCd1234EF5678abcd1234ef5678abcd12345678 and tell me their actual skill score, win rate versus what the odds implied, and their realized PnL?”
Researching a whale before copying trades
“Before I follow this Polymarket whale, can you pull their scorecard for wallet 0xDEADBEEF1234567890abcdef1234567890abcdef — specifically their edge over the odds paid, ROI, and what kinds of markets they tend to specialize in?”
Benchmarking your own Polymarket performance
“Can you score my Polymarket trading performance? My proxy wallet is 0x9999aaaa8888bbbb7777cccc6666dddd5555eeee — I want to know my skill score out of 100, my win rate versus implied win rate, and my realized PnL over my last 200 finished bets.”

Endpoint
GEThttps://www.x402pulse.dev/v1/wallet?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a holistic skill-based evaluation of a specific Polymarket trader's historical performance — especially when you want to distinguish lucky traders from genuinely skilled ones via edge-over-odds and implied win rate comparisons. Prefer this over raw on-chain data queries when you need pre-computed analytics like skill scores, ROI, and trading specialties without doing your own statistical analysis.
Side effects
- Invalid or malformed wallet address (non-0x, wrong length) — returns validation error
- Wallet address has fewer than a meaningful number of completed bets — may return sparse or unavailable scorecard
- Non-Polymarket wallet address passed — no trading history found
- Payment of 0.001 USDC not completed — 402 Payment Required response
- Rate limiting or service unavailability — 429 or 5xx response
