One
Authorization Model
for Humans and AI
Protect workforce access, AI-agent activity, and sensitive enterprise operations with passwordless authentication, scoped authority, and verifiable evidence.
Device → Cryptographic Proof → Verifiable Action

Experience the self-custodial web wallet interface used to authorize requests and manage verifiable identity.
The Root Problem
Why Identity Keeps Failing
Identity failures are structural. As AI and automation accelerate, fragile systems fail more often — and cost more.
Core Platform Capabilities
Core Platform Capabilities
Passwordless MFA
Workforce Authentication
Add passwordless cryptographic authentication to existing applications, portals, and workforce workflows without requiring a full replacement.
Verifiable Identity
Identity Management
Establish a distinct verifiable identity for people, agents, applications, and devices that can be managed and revoked.
Runtime Authorization
AI Agents & Agent-to-Agent
Define what each agent may do, which resources it may access, and how long its authority remains valid. Enforce policy at the moment of action.
Credential Protection
Google Cloud Infrastructure
Keep keys and authorization material outside prompts, agent memory, and exposed runtime components. Google Cloud-backed with enterprise-grade reliability.
Payments and Approvals
Customer-Controlled Litecoin
Customer-controlled Litecoin payments with cryptographic settlement.
Developer and MCP Tools
SDK, REST API & MCP
Full SDKs and MCP integrations for rapid integration. Start with one sensitive workflow and expand over time.

Incremental Integration
Drop-in cryptographic identity. Works alongside your existing stack — no rewrites required.
// npm install @kakr/pteri-sdk
import { PteriAuth } from '@pteri/sdk'
// Verify a signed request — no backend secrets needed
const result = await PteriAuth.verify({
payload: request.body,
signature: request.headers['x-pteri-sig'],
policy: 'payment_authorization'
})
if (!result.isValid) {
throw new UnauthorizedError('Authority not proven')
}
// Deterministic. Binary. No guessing.
