How this service works
A Polymarket wallet's open positions (market, outcome, shares, average price, value, PnL) and latest trades with portfolio totals. Use to follow or vet a trader.
Output
Returns a list of open positions (market name, outcome, shares held, average entry price, current value, unrealized PnL) and a log of latest trades, plus aggregate portfolio totals such as total value and total PnL.
Example use cases
Vetting a trader before copying
“Before I follow this Polymarket trader, can you show me their open positions and PnL for wallet 0xabc123...? I want to see up to 30 rows to get a full picture of their strategy.”
Monitoring personal prediction market portfolio
“What are my current open Polymarket positions and how am I doing overall? My proxy wallet is 0xdef456... — show me all my positions with the latest value and profit/loss.”
Researching a whale's market bets
“I heard this Polymarket whale at 0x789ghi... is heavily positioned on the election markets — can you look up their wallet and show me their top 50 open positions and recent trades?”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/predictions/polymarket/wallet?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain Polymarket portfolio data — open positions, trade history, and PnL — for a specific wallet address, especially for vetting or following a trader. Prefer this over generic blockchain explorers when you need Polymarket-specific enrichment like market names, outcomes, and computed PnL rather than raw transaction data.
Side effects
- Invalid or non-proxy wallet address returns empty results or an error
- Address with no Polymarket activity returns empty positions list
- Limit parameter out of range (must be 1-50) causes a validation error
- Polymarket API unavailability causes upstream timeout or 5xx response
- Checksum-invalid EVM address may be rejected
