Output

Example use cases

Example prompt

“Show me prediction market trading volume and trade counts by exchange for the past 24 hours, broken into 1-hour buckets — so from 2024-06-10T00:00:00Z to 2024-06-11T00:00:00Z with an interval of 3600000 milliseconds.”

When to prefer

Use this endpoint when you need quantitative time-series data (volume and trade counts) for prediction markets aggregated across or broken down by exchange, especially for charting, trend analysis, or comparing activity levels over specific intervals. Prefer this over the narrative recap endpoint when you need raw numeric data rather than a human-readable summary, and over the market search endpoint when you need aggregate activity metrics rather than individual market listings.

Side effects

Missing required query parameters (from, to, interval) returns a 400 error
Invalid ISO-8601 timestamp format causes a parse error
Interval value of 0 or negative may return an error or empty buckets
Time range too large combined with a very small interval may return too many buckets or a timeout
Payment not provided or invalid results in a 402 Payment Required response
Future time ranges may return empty data
