Retrieves rows from an audience with support for filtering, sorting, and pagination. Rows are individual contact or company records; each row contains cells keyed by columnId, where each cell reports its value and a CellState — RESULT (value present), BLANK (no value set), LOADING (enrichment in progress), ERROR (enrichment failed for this cell), or NO_RESULT (enrichment returned no match). Provide filter criteria in the request body to narrow results by column values and conditions using AND/OR logic. Use page[number] and page[size] (default 25, max 100) to paginate through results. Use the sort query parameter with a columnId value and a - prefix for descending order. Use the columns query parameter to limit which columns are returned per row. Returns 200 with a paginated array of rows and navigation links. Returns 400 if filter criteria are malformed or column references are invalid.
