Tick history for prediction markets and related venues
What it is
A historical data service for prediction markets, delivering tick trades, quotes, order-book updates, and onchain fills as daily Parquet files through a REST API or a Python SDK that loads into pandas, DuckDB, or Polars. The main set is Polymarket, with related perpetuals, a BNB-chain prediction venue, and a small Binance spot slice for cross-market research, and market titles plus tags can be downloaded with no account. Independent researchers backtesting those markets are the audience. Tick files beyond five free downloads require a paid plan, the lower paid plan covers a single exchange, and a personal-use license does not allow commercial use.
