+# Agent-to-Agent (A2A) + OID4V integration demo
+
+This demo is built around one of the relevant use cases for Agentic AI identity – VC-based authentication for interaction with Agents.
+It leverages [Agent-to-Agent (A2A)](https://a2a-protocol.org/latest/specification/) and [OpenID for Verifiable Presentations](https://openid.net/specs/openid-4-verifiable-presentations-1_0.html) protocols, specifically demonstrating how to use OID4VP for A2A Task Authentication by implementing [OID4VP In-Task Authentication extension for A2A](https://github.com/DSRCorporation/a2a-oid4vp-in-task-auth-extension/blob/main/v1/spec.md).
+
+The demo is built using [Genkit](https://genkit.dev/) with the OpenAI API.
+Heka Identity Platform is used as a decentralized identity wallet / agent providing support for OID4VP (for both Holder and Verifier parties).
+
+This is a demo code not intended for production-quality usage.
+
+## Scenario
+
+This demo showcases how an AI agent can request additional authentication from a user using the **OID4VP** protocol and how Heka Identity Platform enables such capabilities.
+
+The **Demo Agent** acts as an AI-powered assistant capable of processing user queries and generating responses using Genkit and the OpenAI API.
+The agent is configured to require the user to present a verifiable credential via OID4VP before fulfilling any requests.
+
+The following mapping applies for roles/parties described in extension spec:
+- A2A Client → [CLI client](src/cli.ts)
+- A2A Server → [Demo Agent Server](src/agent/index.ts)
+- OID4VP Wallet → [Heka Mobile Wallet](../../heka-wallet)
+- OID4VP Verifier → [Heka Identity Service](../../heka-identity-service)

+    LLM-->>Agent: AI Response
+    Agent->>CLI: Status Update (state: completed + response)
+    CLI->>User: Display Agent's Response
+```
+
+1.  **Task Initiation**: A user sends a message to the Demo Agent via the A2A CLI.
+2.  **In-Task Authentication Request**: The Demo Agent determines that the context/task requires authentication. It invokes Heka Identity Service API to generate OID4VP authorization request, then sends CLI Client a `status-update` with the `auth-required` state that also includes OID4VP authorization request metadata.
+3.  **OID4VP Flow Initiation**: The CLI client detects the OID4VP request and invokes Heka Wallet to present the requested credentials.
+4.  **Sharing Verifiable Presentation**: Heka Wallet receives OID4VP authorization request, displays requested credentials / claims to a user. After receiving a confirmation, the wallet sends authorization response (containing Verifiable Presentation) to Heka Identity Service verifier endpoint (OID4VP `direct_post.jwt` response mode).
+5.  **Verification**: Heka Identity Service receives and validates the presentation, then sends an out-of-band notification with verification status to the Demo Agent.
+6.  **In-Task Authentication Completion**: The Demo Agent receives notification and makes a decision on proceeding with a task based on verification status.
+7.  **Task Execution**: Once In-Task authentication is successfully completed, the Demo Agent proceeds with the task and generates a response.
+
+## Running the Demo
+
+### 1. Install prerequisites
+
+- Node.js (v18 or higher)
+- yarn v4.9.4
+- Docker
+- An OpenAI API key
+
+### 2. Create an env file
+
+Copy the `.env.example` file to `.env`:
+
+```bash
+cp .env.example .env
+```
+
+You can use `.env` file to define environment-specific and general settings for the demo.
+Most values defined in `.env.example` follow default values used by Heka Identity Platform and can be kept as is.
+
+However, there are values that need to be manually set up:
+- `OPENAI_API_KEY` - add your OpenAI API key there
+- `HOLDER_PUBLIC_DID` - needs to be added after setting up the Heka Wallet app (see the [Run Heka Wallet section](#run-heka-wallet-on-mobile-device))
+
+Other supported values:
+- `DEMO_AGENT_PORT` - Port to be used by the Demo Agent server, defaults to `10003`
+- `CLI_CLIENT_PORT` - Port to be used by CLI Client inbound transport (DidComm inbound transport, used for Mobile Wallet invocation), defaults to `3010`
+- `IDENTITY_SERVICE_URL` - URL of local instance of Heka Identity Service, defaults to `http://localhost:3000`. Must be changed if host, port or API prefix configuration of the instance differs from default values
+- `IDENTITY_SERVICE_ACCESS_TOKEN` - Heka Identity Service API token, default value is a demo token with extremely long validity period. Must be changed if JWT configuration for Heka Identity Service instance was changed
+
+### 3. Setup Heka Identity Platform
+
+#### Run Heka Identity Service
+
+Before running Heka Identity Service instance locally, you need to set up a local instance of Postgres DB.
+This can be done using the following command:
+
+```bash
+docker run --name heka-identity-service-postgres -e POSTGRES_DB=heka-identity-service -e POSTGRES_USER=heka -e POSTGRES_PASSWORD=heka1 -p 5432:5432 -d postgres
+```
+
+To run the service instance itself, go to [Heka Identity Service folder](../../heka-identity-service), install dependencies, set up the DB migrations and run the app:
+
+```bash
+yarn install && yarn migration:up
+yarn start
+```
+
+#### Run Heka Wallet on mobile device
+
+It's strongly recommended to use Android device for running the demo since ADB allows convenient port reversing to localhost.
+
+If you'd like to use an iOS device, you'll need to expose Heka Identity Service ports so they're available for the Heka Wallet app on the mobile device.
+This can be done by using your local network IP address in the Identity Service configuration or leveraging services such as [ngrok](https://ngrok.com).
+
+Install dependencies in `heka-wallet` folder:
+
+```bash
+yarn install
+```
+
+Open `.env` file in `heka-wallet/app` folder and set `ENABLE_EXAMPLE_CREDENTIAL` value to `true`.
+
+(Android only) Enable TCP port reversal to enable access to `localhost` OID4VC endpoints of Heka Identity Service:
+
+```bash
+adb devices
+# Find your device id in "adb devices" output
+adb -s <your-device-id> reverse tcp:3003 tcp:3003
+```
+
+Run the application:
+
+```bash
+# For Android
+yarn run:android
+
+# For iOS
+yarn run:ios
+```
+
+Keep Heka Wallet logs open, complete wallet onboarding process and find a log in the following format: `Public DID: did:peer:...`.
+Copy `<public-did-peer>` value and put it into the demo `.env` file as `HOLDER_PUBLIC_DID` value.
+The public DID value is persistent and will be relevant until you fully reset your Heka Wallet app (by removing application data or reinstalling it completely).
+
+Example did:peer value: `did:peer:2.Vz6MkoWbqNzyX3BaTpECoQsCkKrww2n2pu6F7ZUYq7msD8q5P.Ez6LShhHdY2PSw9QRStKsPoEYDZyfDV8pTGuWTbdc6a2VdsnT.SeyJzIjoid3NzOi8vY2EuZGV2LjIwNjAuaW8iLCJ0IjoiZGlkLWNvbW11bmljYXRpb24iLCJwcmlvcml0eSI6MCwicmVjaXBpZW50S2V5cyI6WyIja2V5LTEiXSwiciI6WyJkaWQ6a2V5Ono2TWtyZ2lmbW1nN1ZWOHQzUXdKTGJnaVJEZnF4UFVyWXZQd25Qcm9aeEQ4cTduTCN6Nk1rcmdpZm1tZzdWVjh0M1F3SkxiZ2lSRGZxeFBVcll2UHduUHJvWnhEOHE3bkwiXX0`
+
+### 4. Install demo dependencies
+
+Install dependencies in `demo` folder:
+
+```bash
+yarn install
+```
+
+### 5. Run the Agent
+
+In one terminal, start the Demo Agent:
+
+```bash
+yarn agent
+```
+
+The agent will start an A2A server (port 10003, can be changed using `DEMO_AGENT_PORT` env variable).
+
+### 6. Run the CLI Client
+
+In a second terminal, start the CLI Client:
+
+```bash
+yarn client
+```
+
+The CLI Client will start an inbound DidComm transport that will use port 3010 (can be changed using `CLI_CLIENT_PORT` env variable).
+
+### 7. Try out integration with the Agent
+
+You can now interact with the Demo Agent. The first message you send will trigger the OID4VP authentication flow.
+Heka Wallet app on your mobile device will display the OID4VP authorization request shortly after – you need to explicitly accept it in the app to pass additional auth requested by A2A Server.
+
+## Disclaimer
+Important: The code provided is for demonstration purposes and illustrates the
+mechanics of leveraging Heka Identity Platform for Agent-to-Agent (A2A) protocol flow with OID4VP In-Task Authentication Extension. When building production applications,
+it is critical to treat any agent operating outside of your direct control as a
+potentially untrusted entity.
+
+All data received from an external agent—including but not limited to its AgentCard,
+messages, artifacts, and task statuses—should be handled as untrusted input. For
+example, a malicious agent could provide an AgentCard containing crafted data in its
+fields (e.g., description, name, skills.description). If this data is used without
+sanitization to construct prompts for a Large Language Model (LLM), it could expose
+your application to prompt injection attacks.  Failure to properly validate and
+sanitize this data before use can introduce security vulnerabilities into your
+application.
+
+Developers are responsible for implementing appropriate security measures, such as
+input validation and secure handling of credentials to protect their systems and users.
