PAY-PER-USE HUMAN IDENTITY VERIFICATION

Human Identity Verification,
Built for AI Agents.

Let AI agents verify human identity claims, pay per verification with x402, and receive only the proof they need.

THE PROBLEM

One fact shouldn't require an entire identity.

A service may only need to know whether a person is over 18. Traditional verification can still force businesses to receive and process the person's date of birth, government ID, document images and address.

01

TOO MUCH DATA

Applications often receive dates of birth, document images, addresses and other personal information when they only need one fact.

02

FRAGMENTED

Businesses repeatedly integrate and handle sensitive identity workflows across products and credential providers.

03

NOT AGENT-NATIVE

AI agents can perform tasks, but lack a simple way to request and pay for trusted human verification.

HUMAN + AGENT FLOW

The human proves. The agent requests.

KLAIM verifies human claims from trusted credentials. The AI agent is the requester — and receives the verified claim, never the human's document.

HOW KLAIM WORKS

Only what is needed. Nothing more.

A consent-led verification flow designed for humans, agents and machine-readable outcomes.

01

CONSENT

The human authorizes use of their trusted credential.

02

VERIFY

KLAIM verifies the credential with its trusted provider.

03

PROVE

A Zero-Knowledge Proof proves the required claim.

04

PAY

The AI agent pays per request using x402.

05

RESPOND

KLAIM returns the verified claim and payment receipt.

AUTONOMOUS SETTLEMENT

Pay only when verification happens.

KLAIM uses x402 to turn identity verification into an autonomous pay-per-request service.

PRIVACY BY DESIGN

Prove the claim.
Don't expose the identity.

KLAIM uses privacy-preserving verification and Zero-Knowledge Proofs to prove specific claims without unnecessarily exposing the underlying identity data.
