Discover series, events and markets, then join recorded prices, spread, volume, liquidity and resolution metadata. The documented observations are one-minute; do not treat every series as an event-by-event feed or assume historical book depth includes a full trade tape. Self-service tiers are Trader, Pro and Ultra, with request volume and granularity selected in the pricing interface. Bulk delivery, derived datasets, custom pipelines and additional support are separately scoped. Confirm each market's first observation rather than assigning the headline archive start to every series. ### Who it is for - Researching resolved and active contracts. - Maintaining historical market panels. - Arranging recurring exports or bounded datasets. ## Features and coverage - **Relational discovery** Navigate series, events and markets. - **Price history** Retrieve recorded outcome-price series. - **Market metrics** Query spread, volume and liquidity observations. - **L2 books** Inspect recorded bid and ask depth. - **Resolved events** Join outcomes and historical contract state. - **Delivery formats** Use REST, Python, Parquet, CSV or JSON exports. - **Custom delivery** Arrange recurring S3 exports or date/category-bounded data. ## Workflows with PolymarketData ### Build a panel Discover markets and retain series/event links; query a common period for prices and metrics. ### Study settlement liquidity Join resolution metadata with books and examine spreads and resting size near settlement. ### Define a pipeline Specify format, date range, destination and update cadence for exports. ## Pricing and total cost Trader, Pro and Ultra are self-service tiers. Select request volume and granularity in the provider's pricing interface. Bulk delivery, derived datasets, custom pipelines and additional support cost separately. ## Getting started **Before you start:** Historical depth and trade tapes are different products. 1. Read documentation and select the dataset. 2. Create an account and API key. 3. Discover a small market set. 4. Request a bounded history and inspect timestamps. 5. Choose API pagination or export delivery to match workload. One-minute historical observations are not necessarily an event-by-event feed.
