Questions
FAQ
How is this different from scraping Polymarket myself?+
The Polymarket public API has no historical data — it returns current live state only. Scraping it yourself means you'd have to have been running a scraper since the market opened to have any history. We've already done that continuously across 450k+ markets since August 2025.
How do I find markets to query? I don't have the slugs memorized.+
Start with the /markets discovery endpoint. Search by keyword, filter by category or date range, and it returns slugs, IDs, and metadata. It's designed to be your first call before any historical pull.
Can I use this to power a live dashboard or does it only work for research?+
Both work. Research workflows use historical windows; dashboard pipelines can poll the latest data on a schedule. The same endpoints and auth work for either use case.
Does the free plan have enough to evaluate whether this is worth paying for?+
Yes. The free tier gives you real access to real historical data. Pull a market you care about, run some analysis, and see if the data quality and coverage meets your needs before upgrading.
