Keyword Report

Keyword performance with Quality Score (and its three components) for every keyword that had impressions in the period, sorted by cost. DATE: period ('today', 'last_7_days', ... or 'YYYY-MM-DD[:YYYY-MM-DD]') overrides days; days=0 = today. `active` = the keyword is serving now; paused/removed keywords that had impressions in the period are included as history. include_zero_impressions=true adds keywords with no impressions in the period (the full keyword inventory). Each row has `flags`: low_quality_score (QS 1-3) and/or zero_conversion_spend (cost > 0, no conversions). Summary fields (total_rows, active_count, active_match_types, quality_score_histogram, low_quality_score_total/cost, zero_conversion_spenders_total/cost) cover all rows; only = low_quality_score | zero_conversion_spenders | active returns just those rows. limit = rows in this response (no upper bound; 0 = as many as fit, about 380 KB); when has_more is true, page_token=next_page_token returns the next rows without credits or a new query; offset=next_offset also works.
