Backfill checks domains found in English Wikipedia’s external links and publishes their registry and DNS status in an index and API.

Landing page captured for the 2026-10-23 issue.

For: Wikipedia link maintainers and domain researchers
Worth noticing: The index links each sample domain to the Wikipedia articles carrying its links and separates parked names from registered names with no DNS.

Field notes

The page describes a pipeline that harvests English Wikipedia’s live external links, then checks registrable domains through RDAP and DNS-over-HTTPS. Its displayed status classes distinguish names with no registry record from parked domains, domains with resolving DNS, and registered names without DNS; inconclusive checks are also counted. The API table lists free basic lookups and paid deep endpoints, with payment handled per call through x402.
