KYE App Store · reference apps, not commercial products

Reference authority surfaces on KYE.

The KYE App Store indexes reference apps on KYE Protocol — not connectors, not plugins, and not yet commercial products. Each card lists the open contracts shipping with v1.0: schemas, sample payloads, manifest, webhook verifier, SDK adapters. Build on top, fork, or take to production yourself.

Connector Hub integrates KYE. App Store productises KYE. Plugin Marketplace extends KYE.

Mobile demo · the user-facing showcase

KYE Authority Walletcontrol AI agents from your phone.

An Android / iOS demo (Expo / React Native) that turns the protocol into an experience. Create AI agents, grant scoped authority, approve / deny / revoke, inspect Decision Maps, view Evidence Packs. Synthetic data; simulated agent and payment flows.

  • Flagship scenario: Let an AI shopping agent buy on my behalf, but only up to £50, only from approved merchants, and require my approval above £25. The phone receives a request for £34.99 and asks approve / deny / modify scope / revoke.
  • Six screens: Home, Agent (with revoke + cascade demo), Approval, Decision Map, Evidence Pack, Developer mode (request / decision / evidence / webhook JSON + TS SDK snippet).
  • Five demo scenarios shipped: agent-backed purchasing, travel booking, open-banking payment-prep, healthcare appointment booking, legal contract approval, security key rotation.
  • Demo vs Pro: the demo is proprietary and runs on synthetic data. The production version — KYE Authority Wallet Pro — ships real Gateway integration, enterprise approvals, push notifications, evidence archive (commercial). Banks and payment platforms get KYE Mobile Approval Gateway.

Demo app uses synthetic data and simulated agent / payment flows. It does not process real payments or replace bank, wallet, legal, healthcare, or identity systems.

Payments & commerce · 4 apps

The agentic-payments stack.

KYE Payment Authority Gateway

Runtime authority gateway for agent-backed payments and delegated purchasing. Checks actor · principal · payment instrument · merchant · basket · amount · currency · jurisdiction · authority grant · approval threshold · state · risk · policy.

Verify delegated payment authority before an agent, workflow, wallet, IPG, MPG, checkout, or payment rail acts. Before the payment is authorised, KYE proves the agent was authorised.

Open: payment authority schemas · sample decision payloads · webhook verifier · connector manifest · SDK examples.

KYE Checkout Guard

Detect agent-backed checkout flows; verify whether the agent is allowed to buy this basket from this merchant using this instrument under the customer's limits. Outside scope → deny / pause / require approval before payment execution.

Open: checkout authority schema · basket-hash schema · sample plugin · webhook verifier · SDK examples.

KYE Agent Purchasing Reference App

Reference app showing how a customer delegates limited card-purchasing authority to an AI agent. KYE checks the agent, customer, card token, merchant, basket, spend limits, state, and approval threshold before the purchase proceeds. Every purchase produces a Decision Map and evidence pack.

Open: reference architecture · sample schemas · sample decision payloads · sample evidence JSON · demo connector manifest.

KYE IPG / MPG Connector

Add KYE pre-authorisation checks to internet and mobile payment gateways. Verify agent authority, payment-instrument state, merchant category, basket hash, risk state, and approval threshold before the gateway processes the payment.

Open: IPG/MPG connector manifest · sample pre-authorisation request · sample webhook event · signature verifier · test harness.

Sandbox & conformance · 2 apps

Test agentic finance with audit-ready evidence.

KYE UAE Open Finance Sandbox Connector

Add KYE authority decisions, evidence packs, Decision Maps, and conformance evidence to UAE-style open-finance sandbox testing. Test customer consent, API-client authority, AI finance agents, transaction initiation, account access, and evidence flows. KYE turns sandbox actions into replayable authority decisions and signed evidence packs.

Open: sandbox authority schemas · synthetic test fixtures · sample evidence payloads · sample API adapter.

KYE Regulatory Sandbox Evidence Harness

Test agentic finance, delegated authority, and AI-governance workflows in sandbox environments with Decision Maps, signed evidence packs, self-audit reports, and conformance outputs.

Pensions: dashboards, advisers, retirement agents.

Govern pension dashboard, adviser, scheme, provider, ISP, and retirement-agent access with state-aware authority decisions and evidence packs. KYE proves who viewed or acted on pension data, on whose authority, for what purpose, within what scope.

Open: pension authority schema · member consent model · sample find / view authority payloads · connector manifest.

KYE Pension Sandbox Harness

Test pension dashboard and provider authority flows with synthetic members, schemes, API endpoints, adviser roles, retirement agents, Decision Maps, and evidence packs.

Make KYE available to MCP-compatible agents.

KYE MCP Server & Tool Governance Gateway

Expose KYE authority checks, schemas, dictionaries, capability manifests, Decision Maps, and evidence packs to MCP-compatible agents, IDEs, and developer tools. Agents can inspect authority; production systems still enforce through the KYE Runtime Gateway.

Open: MCP server skeleton · read-only MCP tools · schema resources · dictionary resources · sample decision tools · local dev MCP server.

Audit & certification · 2 apps

Evidence, not screenshots.

KYE Evidence Pack Viewer

Replay decisions, verify signatures, inspect authority grants, check entity state, review payload hashes, trace audit events, and map evidence to controls. For auditors, regulators, banks, enterprises, and customers.

KYE Certification & Conformance Portal

Run KYE self-tests, publish self-attestations, submit implementations for review, and earn KYE Self-Tested → KYE Self-Attested → KYE Conformant → KYE Certified badges.

Open: conformance fixtures · self-attestation schema · certification record schema · basic CLI reporter.

App manifest

Every app ships a kye.app_manifest.v1.

App manifests declare what the app does, which profiles it supports, the capabilities it exposes, and the deployment modes it supports.
