WHOIS · Public registry lookup

Look up any verified AI — or any public name or brand.

Search by AI Identity ID (e.g. aii_01H7X…), surface handle (e.g. telegram:@acmebot), a person's name, or a brand. We also flag identities claiming to act on behalf of a person or brand without authorisation.

Building on this? Use the machine-readable WHOIS API: GET /api/v1/whois/[id]. Free up to 1,000 lookups/month. Read the spec.
