Why burn 100,000 residential proxy requests scraping Google for URL footprints when you can query the CommonCrawl columnar Parquet index directly using `DuckDB` in 30 seconds? ```sql INSTALL httpfs; LOAD httpfs; SELECT url, url_host_name, fetch_status FROM read_parquet('s3://commoncrawl/cc-index/table/cc-main/warc/crawl=CC-MAIN-2026-38/subset=warc/*.parquet') WHERE url_path LIKE '%/wp-json/wp/v2/users%' AND fetch_status = 200 LIMIT 5000; ``` Zero captchas, zero proxy burn, and you get clean domain lists ready for direct verification.
