General Overview of the Indexer

Our Polymarket Indexer provides unified access to Polymarket data: on-chain events (all trades, condition creation/resolution, position split/merge, payout redemption) and CLOB data (order book, price changes, best bid/ask, recent trades). Everything is stored in ClickHouse (only order books are stored in CSV), so historical queries and aggregations are executed very fast. An important point: the solution is unlimited — history is not truncated and there are no limits on the number of requests; you work with the full dataset.

For on-chain analysts, this is a convenient way to link wallet activity with markets and events: who traded and how, how liquidity/spreads changed, how the market reacted to resolutions. For ML engineers and algo traders, the value lies in the complete set of trades and tick-level order book data: you can reconstruct the order book over time, calculate microstructure features, and run backtests on the full history without bottlenecks in data extraction speed.

For service builders and traders, this is a foundation for products: dashboards, alerts, signals, wallet scoring, and risk metrics. Compared to solutions based on public APIs, you get more control, a stable data schema, and significantly faster analytical queries — while the system scales to any volume.
