Request
Path parameter
Query parameters
The inclusive range may contain at most 366 days and may begin no earlier than
2020-01-01. When a request reaches today but the newest completed daily bucket is one or two days behind, the service shifts both dates backward by the same amount. Always treat the returned start_date and end_date as authoritative.
Top-market and top-category composition is included only for windows of 31 days or fewer. Longer history requests preserve the same response shape and return empty top_markets and top_categories arrays.
Example
Response shape
days contains one row for every requested UTC date, including explicit zero-valued days. Buy and sell volume use the same outcome-share par-notional basis and add to total volume. active_traders is the distinct attributed trader count for that Builder and day.
Each top_markets and top_categories row includes rank, volume, fills, trader-paid fees, and buy/sell volume. Market rows also include nullable condition_id, title, slug, image, and category.
