Inspect recorded correlations between prediction markets in one category

How to use this Tool

Use the deployed input fields below. Required fields must be supplied; optional filters narrow the result.

queryParams.limit (Optional): Results per page. Defaults to 20.

queryParams.offset (Optional): Pagination offset. Defaults to 0.

queryParams.category (Required): Category (correlations are within-category only).

queryParams.condition_id (Optional): Filter to pairs involving this market.

queryParams.min_correlation (Optional): Minimum absolute correlation. Defaults to 0.5.

What this Tool returns

Returns paired market questions and condition IDs, the recorded correlation coefficient and overlapping-day count.

Response fields and how to read them

The table follows the official response contract, including nested fields and useful response metadata. [] denotes an array item. Required means required within its parent object, not that a conditional parent always exists. A nullable type permits null; an optional field can be absent. Use the documented conditions below to distinguish missing, empty and zero values. Units and reporting windows apply only where explicitly documented.

Coverage, units and freshness

Correlation is a coefficient, not a percentage or proof of causation. Short overlap windows may make comparisons less informative.

Inspect any returned observation time, cache status, watermark, pagination and errors using their documented meanings. A successful request alone does not establish complete coverage. Where no freshness or completeness guarantee is documented, treat it as unknown. Saved Examples are historical and viewing them does not refresh data or execute a new call.

Surf supplies this endpoint through its Data API. Response contract and deployed Tool inputs reviewed on 2026-10-03 against official OpenAPI v0.2.102. This is a contract review date, not a data observation time. Coverage depends on the selected endpoint and request.
