# Data API on Polymarket

> Wallet-level PnL, leaderboards, trade logs, and tax statements for any Polymarket address, derived from on-chain Polygon settlement.

The [Data API](/products/data-api) is fully supported on Polymarket. Every figure is derived from on-chain Polygon settlement records and replayed through a share-level FIFO cost-basis engine, no off-chain estimates.

It works on **any** public Polymarket address, not just wallets managed through Bravado, and the read endpoints require no funded account.

## Accounting model

PnL is computed under the Prediction Market Wallet Accounting Standard (PMWAS), so cost basis is consistent across every response rather than recomputed per endpoint.
