Third-party Integration

Third-party developers can integrate with the Penverse ecosystem using various authentication modes, subscription-based API/SDK interactions, and structured integration mechanisms. The following sections outline the available methods, pricing models, and a sequence diagram illustrating the integration flow.

---

1. Integration Overview

Third-party applications can interact with Penverse through:

• Penverse API – RESTful endpoints to access research data, smart contracts, governance, and transactions.

• Penverse SDK – Simplifies integration by providing pre-built functions for authentication, research retrieval, smart contract execution, and more.

Applications integrating with Penverse can:

• Fetch and analyze decentralized research data

• Execute smart contracts for transactions and governance

• Participate in DAO voting and staking

• Purchase and trade research-based NFTs

• Implement user authentication via API keys or blockchain wallets

---

2. Authentication Modes

Penverse provides multiple authentication mechanisms:

2.1 API Key Authentication

• API keys can be generated from the Penverse Developer Portal.

• Required in the request headers for secure communication.

Example:

Authorization: Bearer <your-api-key>

2.2 OAuth-Based Authentication

• Supports OAuth 2.0 for applications requiring delegated access.

• Users can authorize third-party apps to access their research profiles.

2.3 Blockchain Wallet Authentication

• Users authenticate via MetaMask, WalletConnect, or Ledger.

• Transactions are signed on-chain for security.

Example Workflow:

1. User connects wallet → MetaMask prompts authentication.

2. App receives user’s blockchain address and signed message.

3. Access granted based on wallet verification.

4. Integration Mechanisms

4.1 API Integration

Third-party systems can integrate via REST API calls. Below is an example of a research paper retrieval request.

Example API Request:

GET /research/papers?keyword=AI&year=2023
Authorization: Bearer <API_KEY>

Response:

{
  "papers": [
    { "title": "Decentralized AI in Research", "author": "Dr. Alice Doe", "year": 2023 }
  ]
}

4.2 SDK Integration

For ease of development, Penverse provides SDKs for Node.js, Python, and other platforms.

Example SDK Integration:

import Penverse from '@penverse/sdk';
const penverse = new Penverse({ apiKey: 'your-api-key' });
const papers = penverse.get_research_papers({ keyword: 'AI' });

4.3 Smart Contract Interaction

Penverse supports blockchain-based transactions. Third-party apps can execute smart contracts for purchasing research papers.

Example Smart Contract Execution:

const transaction = penverse.execute_smart_contract({ contract_id: 'SC-001', parameters: {} });

5. Sequence Diagram

   +------------+         +------------+         +------------+
   |  Third-Party App | ---> | Penverse API | ---> | Blockchain |
   |                | <--- |            | <--- |            |
   +------------+         +------------+         +------------+

1. The third-party application sends an authentication request.

2. The Penverse API verifies credentials and grants access.

3. The application fetches research data, executes smart contracts, or participates in governance.

4. If blockchain transactions are involved, the request is sent to the blockchain network.

6. Best Practices for Integration

• Use OAuth authentication for better security and delegated access.

• Rate-limit API calls to avoid service disruptions.

• Cache frequently requested research data to reduce API overhead.

• Implement logging and error handling for all API transactions.
