domain-ownership-proof

Xynaptic Domain Ownership Proof — prove you control a domain (or a GitHub repo) without exposing an email address: we generate a challenge token to publish as a DNS TXT record or at /.well-known/, then verify it and return a signed proof with the method used, the resolved record, the timestamp and a verification verdict. Useful for KYC-lite, allowlisting and agent identity. POST body: { domain, method }.
