One number. Human, verified.
Planetary ID is a digital identity bound to you by your passkey — fingerprint or Face ID. No email, no password. Use it to prove human presence on the web and to AI agents. Your biometrics never leave your device.
Planetary IDs
How
an identity
is made.
Three cryptographic pillars. No personal data. A number that is signed, verifiable, and stored with no link to who you are.
Biometric verification
The same technology as Apple Pay. Your fingerprint or Face ID is processed entirely on your device. It is never sent anywhere.
On-device · WebAuthnCryptographic authenticity
Every ID is signed with Ed25519. Anyone can verify it against our public key. It cannot be forged.
Ed25519 · JWTYours forever
One ID or ten, all bound to you alone. The database stores nothing but a number and an irreversible hash of your passkey.
Permanent · Non-transferableDATA
and a hash no one can reverse.
Proof of human presence,
as a protocol.
Your agent needs to know there's a real person on the other end? X-EGO Human Proof is an MCP server with three tools: request a verification link, verify the signed proof, check for returning users. Proofs are EdDSA-signed JWTs — 180 seconds, single-use, replay-protected. Each service sees a stable pairwise ID that no other service can link.
What it proves: a person with a registered passkey, who paid for their ID, approved this verification — now, for your service specifically. What it doesn't prove: global uniqueness. Sybil resistance is cost-bounded: one identity, one payment.
Free tier: 500 verifications per audience per month. Higher-volume tiers available — get in touch.
Got an ID? Verify it.
Every Planetary ID can be independently verified against the X-EGO public key. No login, nothing personal shared — just the number.
