@privado-langchain-sdk/agent-id-sdk v1.0.0

@privado/agent-id-sdk

A SDK for signing and verifying AI agent responses using Lit Protocol.

Installation

npm install @privado/agent-id-sdk

Quick Start

const { createPrivadoCallback } = require('@privado/agent-id-sdk');
const { createOpenAIFunctionsAgent, AgentExecutor } = require("langchain/agents");
const { ChatOpenAI } = require("langchain/chat_models/openai");

async function main() {
    // Create callback handler
    const privadoCallback = createPrivadoCallback({
        litPkpPublicKey: process.env.LIT_PKP_PUBLIC_KEY,
        ethereumPrivateKey: process.env.ETHEREUM_PRIVATE_KEY,
    });

    // Initialize agent
    const llm = new ChatOpenAI({
        temperature: 0,
        modelName: "gpt-3.5-turbo",
    });

    const agent = await createOpenAIFunctionsAgent({
        llm,
        tools: [],
    });

    const executor = new AgentExecutor({
        agent,
        tools: [],
        callbacks: [privadoCallback],
    });

    // Run the agent
    const result = await executor.invoke({
        input: "What is the capital of France?"
    });

    console.log("Agent response:", result);
    console.log("Signed message:", result.signedMessage);
    console.log("Agent DID:", result.agentDID);
}

Configuration

The SDK requires two environment variables:

• LIT_PKP_PUBLIC_KEY: Your Lit Protocol PKP public key
• ETHEREUM_PRIVATE_KEY: Your Ethereum private key

Features

• Sign AI agent responses using Ethereum private keys
• Generate Decentralized Identifiers (DIDs) for agent responses
• Verify the authenticity of agent responses
• Seamless integration with LangChain

Creates a new PrivadoCallback instance.

Parameters

• config (Object):
  • litPkpPublicKey (string): Your Lit Protocol PKP public key
  • ethereumPrivateKey (string): Your Ethereum private key
