Our take

This server provides passive subdomain discovery, returning known or historical subdomains for a given domain. It is mainly for security research, recon, or inventory work where quick lookup matters more than guaranteed freshness. The scope is narrow and understandable, but passive data can be incomplete or stale, so results should be treated as a starting point rather than ground truth.
