ডেটা API

Definition

The Polymarket Data API is Polymarket's public REST API surface for historical and near‑real‑time market data focused on user activity: positions, trades, holders, open interest and related activity streams. It is read-only and intended for analytics, reporting, and third‑party dashboards.

In context

You encounter the Data API when you need programmatic access to who holds outcome tokens, recent trade history, open interest by market, and position snapshots. Unlike the Gamma API, which surfaces markets, events, tags and series, the Data API specialises in the activity and ledger‑style views that feed analytics pipelines and portfolio trackers.

Typical uses

• Fetching a market's recent trades to reconstruct a time series for price charts.
• Listing holders and large positions to approximate concentration and liquidity.
• Calculating open interest across markets for risk and exposure metrics.

Implementation notes

The Data API is a public REST endpoint (base URL: https://data-api.polymarket.com). It requires no authentication for read operations. Use it alongside the Gamma API and the CLOB endpoints to combine market metadata with ledger data for complete analytics.
