OnPage API Duplicate Tags

Pages within a crawl sharing a title or meta description. ⚠️ type accepts exactly duplicate_title or duplicate_description - anything else, including the obvious 'title', is rejected with status_code 40501 inside an HTTP 200. accumulator narrows the result to pages carrying one specific tag value. Returns total_pages_count, pages_count, items_count and items. Reads a finished crawl, so it needs the id from post_dataforseo_on_page_submit and returns crawl_progress plus a crawl_status of max_crawl_pages, pages_in_queue and pages_crawled - check those before trusting a small result, because a crawl still running simply has less to report. For duplicated body content instead, use post_dataforseo_on_page_duplicate_content. 💰 Free upstream: querying a finished crawl costs nothing, only the crawl itself does.
