AI agents are signing up for services, burning API quotas, and flooding platforms — and nobody can tell them apart from real users. The Certified H badge is a cryptographic proof of personhood that you own and any service can verify. One API call confirms you're real. Your identity stays private. The proof is public.

Claim a place in the human tree
You begin by typing your name. The system asks for your parents, then links those claims to existing genealogical records and trusted trees such as Geni, census entries, obituaries, and verified relatives. A synthetic account can invent a name; it cannot easily invent parents, grandparents, cousins, records, and living people who all cross-confirm the same place in the tree.
This is the internet version of an old legitimacy test. In a small town, or in medieval times, a stranger became known because real people could vouch for where they fit: whose child, whose sibling, whose neighbour. Certified H turns that social fact into a private proof, so services can stop Sybil attacks without seeing your family tree.
It is a kind of 3D White Pages: not a flat snapshot of names and addresses, but a time-aware graph that traces people through records, relationships and timestamped additions to the blockchain of records. A higher fraud threat surface requires deeper correlations with the past before a claim on reality can be trusted. The same graph also preserves hyperlocal history that would otherwise disappear.
I am a human person who does human things like breathing and having feelings.

// FAQ
Questions
What does this actually prove?
That you are a unique, living biological human — verified through genealogical connections to other humans, not just a scanned ID. A fake identity can forge a document; it can't fabricate three generations of cross-referenced relatives.
Is my data safe?
Yes. Your genealogical data is never exposed. When someone clicks your badge, they see an anonymous cryptographic proof — not your family tree, not your name, not your ID. We verify, then redact.
How do I display my badge?
After verification, you receive a unique badge URL and embeddable widget. Add it to your social bios, website, or profile. Clicking it takes viewers to a verification page confirming the proof.
How is this different from standard KYC?
Standard KYC checks a government ID against a name. We verify you're a real node in the human family graph — anchored to other verified humans. It's a deeper proof, and unlike KYC, we never store or reveal your personal documents.
Can services use this to block bots and AI agents?
Yes. Any platform can query humansonly.info/api/ho/check/{id} to confirm a user's humanity before granting access. It's a single HTTP call returning {"is_human": true}. Free to check, impossible to forge.
