Add Identity and Authorization
to Any Workflow
Use PTERI APIs, SDKs, and MCP integrations to authenticate users, authorize agents, protect credentials, and verify sensitive actions.
The Developer Problem
As systems scale, secret-based authorization becomes fragile, difficult to audit, and dangerous to revoke safely.
The Failure of Shared Secrets
Leaked Credentials
API keys are copied, logged, leaked, and reused across systems.
Persistent Access
Long-lived tokens remain active long after the original intent has expired.
Excessive Permissions
Credentials grant more access than a person or agent actually needs.
Unclear Agent Authority
An agent may have access without proof that a user or organization approved its specific action.
The Shift: From Secrets to Verified Intent
APIs Built on Verifiable Authority
Signed Requests
Requests are signed by a device-owned or agent-delegated key — no shared secret needed.
Verified Authority
Identity, delegation, scope, policy, and expiration are evaluated at request time.
Policy Evaluation
Applicable policy is evaluated at the moment the action is requested.
Allow or Deny
Every request produces a verifiable allow or deny result with evidence.
Quickstart — Pseudocode
Pseudocode — illustrative only// Pseudocode — see docs.kakr.ai for real SDK and endpoints // Step 1: Identify the user or agent const identity = pteri.identify({ type: 'user', credential: deviceKey }); // Step 2: Define the requested action and scope const authorization = await pteri.authorize({ identity: identity, action: 'payment.send', policy: 'payment_authorization' }); // Step 3: Evaluate — allow or deny with evidence if (!authorization.allowed) { throw new Error('Insufficient authority'); } // Step 4: Execute — evidence is attached to the action executeAction(authorization.evidence);
This is illustrative pseudocode. Install a real SDK and use real endpoints from docs.kakr.ai.
Core API Capabilities
Passwordless MFA
Add passwordless authentication to existing applications, portals, and workforce workflows.
Agent Authorization
Give every AI agent a verifiable identity and narrowly scoped authority that can be managed and revoked.
Runtime Authorization
Verify identity, scope, context, and policy before a consequential action is executed.
Action Evidence
Produce tamper-evident evidence connecting an action to its identity, authority, and governing policy.
Payments and Approvals
Customer-controlled Litecoin payments with cryptographic approval and policy-based spending controls.
From Identity to Verified Action
Identify — establish a verifiable identity
Authenticate — confirm without shared secrets
Authorize — define scope, policy, expiration
Verify — evaluate authority at request time
Allow or Deny
With verifiable evidence
MCP and Tool Security
PTERI documentation includes MCP-oriented capabilities for verifying authority when agents access tools and services. Agents operate within verifiable, scoped boundaries — auditable and revocable.

Litecoin proof-of-work components used as the independent verification layer beneath PTERI's authorization evidence — kept separate from the identity and authorization APIs above.
Supported Environments
Works alongside existing identity providers, applications, AI agents, MCP servers, and cloud infrastructure. Start with one sensitive workflow and expand over time.
