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™.

KYE Protocol authority + evidence record: purpose request, admissibility check, decision map, context seal, evidence pack and replay proof for one governed action.
Illustrative — the authority + evidence record KYE Protocol produces for a single governed action (sample data).
Mobile demo · the user-facing showcase

KYE Authority Wallet™ — control 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.

Every claim here is backed by the open KYE Protocol™ contracts and verifiable end-to-end from the publisher's JWKS — you check it yourself, you don't take our word for it.

KYE Payment Authority Gateway™

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.
