This record is unclaimed

Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.

Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"rdap-api","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

Tools observed via MCP handshake

domain-lookup — Look up normalized RDAP registration data (registrar, status, dates, nameservers, contacts) for a domain name.
bulk-domain-lookup — Look up normalized RDAP registration data for several domain names in one pooled call. Requires a Pro or Business plan; every domain in the batch counts against
ip-lookup — Look up normalized RDAP allocation data (network range, holder, country, status, geofeed URL) for an IP address or CIDR block.
asn-lookup — Look up normalized RDAP data (holder, country, status, registration dates) for an autonomous system number.
nameserver-lookup — Look up normalized RDAP data (IP addresses, status, sponsoring registrar) for a nameserver hostname.
entity-lookup — Look up normalized RDAP data for an RIR entity handle — an organization or contact identifier such as "GOGL" or "ORG-RIEN1-RIPE". Only ARIN, RIPE, APNIC, LACNIC
tlds — List the TLDs this API can query, or describe one: which RDAP server answers for it, since when it has been supported, and how often that server fills each fiel
