Technical details
Endpoint
POSThttps://api.vextorium.com/polymarket-cartera-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need detailed open-position data for a specific Polymarket wallet, including per-market PnL, share counts, price comparisons, redeemability status, and aggregated portfolio totals. Prefer this over generic blockchain explorers when you want Polymarket-specific semantic data (outcomes, market names, PnL) rather than raw on-chain token balances.
Side effects
- Invalid or malformed wallet address returns empty positions array or error
- Wallet with no Polymarket activity returns zero positions and zero totals
- Polymarket API unavailability causes upstream fetch failure
- Rate limiting or timeout if Polymarket data source is slow
- limite parameter ignored or mishandled if not a positive integer
