The Root Problem

Why Identity Keeps Failing

Identity failures are structural. As AI and automation accelerate, fragile systems fail more often — and cost more.

Defining Properties

Identity as
Cryptographic
Authority

No shared secrets. No custodial storage. No probability scores. Just cryptographic proof.

Identity bound to on-device cryptographic keys

Keys generated and held solely by the authority holder

Zero shared secrets exchanged with any server

Proof is stateless and independently verifiable

No confidence scores or reputation systems used

PTERI Authority Model
Zero-Custody · Deterministic · Verifiable
Device-Bound KeysGenerated & stored only on your device
Cryptographic SignaturesEvery action signed — no shared secrets
Litecoin PoW AnchoringCryptographically anchored, globally verifiable
Binary OutcomeAllow or deny — no ambiguity, no guessing
If authority proven → Access Granted. If not → Access Denied.

Core Platform Capabilities

Core Platform Capabilities

01

Passwordless MFA

Workforce Authentication

Add passwordless cryptographic authentication to existing applications, portals, and workforce workflows without requiring a full replacement.

02

Verifiable Identity

Identity Management

Establish a distinct verifiable identity for people, agents, applications, and devices that can be managed and revoked.

03

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.

04

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.

05

Payments and Approvals

Customer-Controlled Litecoin

Customer-controlled Litecoin payments with cryptographic settlement.

06

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.

Developer Experience

Designed for
Incremental Integration

Drop-in cryptographic identity. Works alongside your existing stack — no rewrites required.

Drop-in SDK
npm install and integrate in minutes. Works alongside OAuth, JWT, and existing auth flows.
Incremental Adoption
Layer PTERI on top of existing systems. Start with MFA, expand to payments or AI.
Language Agnostic
SDKs for JS, Python, Java, PHP, Go. REST API works with any stack.
MCP2 AI Integration
AI-powered MCP2 tools let LLMs and agents call PTERI to sign, verify, or delegate.

verify.ts
TypeScript
// 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.
return processTransaction(result.claims)
