Frequently asked questions

The basic lookup (GET /v1/domain/{domain}) splits technologies into separate active and historical arrays. This history endpoint returns a single unified list with a status field (active or removed) for each technology, which makes it easier to track changes over time.
History depth varies by domain. TechnologyChecker’s crawl data goes back up to 20 years for well-established domains. The first_seen and last_seen dates show exactly when each technology was first detected and when it was last confirmed or removed.
Poll this endpoint periodically (e.g., weekly or monthly) and compare the status field across responses. Technologies that change from active to removed mean the domain dropped that tool. New entries with active status show recent adoptions. This is useful for competitive intelligence and churn detection.
