Interact with AI service to create an Agent

Here is a guide for interacting with AI service endpoints to create an agent.

Prerequisites

Node.js environment

Before you begin, configure your .env file. Here is an example:

# Network Configuration
PROVIDER_RPC=your_provider_rpc_url_here

# Wallet Configuration
AGENT_PRIVATE_KEY=your_private_key_here
AGENT_ADDRESS=your_wallet_address_here

# IPFS CONFIG for managing budgets

LIGHTHOUSE_API_KEY=
IPFS_PROJECT_ID=
IPFS_PROJECT_SECRET=

# Project Configuration
PROJECT_ID=

# Resource Budget (Defaults to 5)
DEFAULT_RESOURCE_BUDGET=5

Resource Budget Management

Before using any service endpoints, you must configure and manage your resource budget. The following functions from src/services/Skynet.ts handle budget management:

Create initial budget

const createBudget = async (appName: string, subnetId: string) => {
    const skyNode = await getSkyNode();

    if (!process.env.PROJECT_ID) {
        return {
            success: false,
            nftId: "",
            appId: 0
        }
    }

    const contractApp = {
        nftID: process.env.PROJECT_ID!,
        appID: "",
        appName: `${appName}`,
        appPath: Buffer.from(STORAGE_TYPE.LIGHTHOUSE + '/').toString('hex'),
        modPath: Buffer.from(STORAGE_TYPE.LIGHTHOUSE + '/').toString('hex'),
        appSubnetConfig: [{
            resourceType: [1],
            resourceCount: [1],
            multiplier: [1]
        }],
        subnetList: [subnetId],
        cidLock: false
    }

    const subscriptionParam = {
        licenseAddress: "0x0000000000000000000000000000000000000000",
        supportAddress: "0x3C904a5f23f868f309a6DB2a428529F33848f517",
        platformAddress: "0xBC6200490F4bFC9092eA2987Ddb1Df478997e0cd",
        referralAddress: "0x0000000000000000000000000000000000000000",
        createTime: 0
    }

    const createTimeResp = await skyNode.dripRateManager.getSubscriptionParam(process.env.PROJECT_ID!);
    if (createTimeResp?.success && createTimeResp.data.createTime > 0) {
        subscriptionParam.createTime = createTimeResp.data.createTime;
    }

    const createAppResponse = await skyNode.appManager.createApp(
        contractApp,
        subscriptionParam,
        {
            licenseFactor: 0,
            supportFactor: 0,
            platformFactor: 0,
            referralFactor: 0,
            discountFactor: 0,
            referralExpiryDuration: 0,
            createTime: 0,
            daoRate: 0
        },
        [etherToWei(Number(process.env.DEFAULT_RESOURCE_BUDGET!), 18).toString()],
        {},
        {
            modAttribVar: {},
            contractParam: {},
            loggerURL: "https://appsender.skynet.io/api/appStatus"
        },
        async (status) => {
            if (status === CRUD_APP_STAGE.CREATE_SUCCESSFUL) {
                console.log("status", status);
            }
        },
        { fetchAppList: true, fetchSubscriptionParam: true, fetchBalanceForSubscription: true, getDeploymentStatus: false }
    );
    return createAppResponse;
}

Verify and Auto-top up Budget

const verifyBudget = async (appName: string, subnetId: string) => {
    const appList = await fetchApps();
    if (!appList) return false;
    
    const subnetList = appList.flatMap(app => app.subnetList);
    if (!subnetList.includes(subnetId)) {
        await createBudget(appName, subnetId);
        return true;
    };
    
    const verifyBudgetResponse = await getSubnetBalance(subnetId);

    if (verifyBudgetResponse && Number(verifyBudgetResponse) < (Number(process.env.DEFAULT_RESOURCE_BUDGET!) * 0.5)) {
        await addBudget(subnetId);
        return true;
    }
    return true;
}

Add More Budget

const addBudget = async (subnetId: string) => {
    const skyNode = await getSkyNode();
    const valueInWei = ethers.utils.parseEther(process.env.DEFAULT_RESOURCE_BUDGET!);
    const addbalanceRespose = await skyNode.contractService.SkynetWrapper.addBalanceByBuyingXCT(
        process.env.PROJECT_ID!,
        [subnetId],
        [valueInWei.toString()],
        { value: valueInWei }
    );
    return addbalanceRespose;
}

Required environment variables for budget management:

PROVIDER_RPC=            # Your RPC provider URL
AGENT_PRIVATE_KEY=       # Your wallet private key
PROJECT_ID=              # Your project NFT ID
DEFAULT_RESOURCE_BUDGET= # Default budget amount in ETH

Example usage:

// Before making API calls, verify budget
await verifyBudget("MyApp", "4");

Ensure sufficient budget is maintained to use the service endpoints
The system automatically tops up when balance falls below 50% of DEFAULT_RESOURCE_BUDGET
Initial budget creation is required for first-time subnet usage
Budget management functions require proper wallet configuration with sufficient funds

SDK Initialization

import SkyMainNodeJS from '@decloudlabs/skynet/lib/services/SkyMainNodeJS';

const initializeSkyNodeCrypto = async (): Promise<SkyMainNodeJS> => {
    if (!global.initializedAppCrypto) {
        const envConfig = {
            JRPC_PROVIDER: process.env.PROVIDER_RPC!,
            WALLET_PRIVATE_KEY: process.env.AGENT_PRIVATE_KEY!,
            STORAGE_API: {}
        };
        global.initializedAppCrypto = new SkyMainNodeJS(envConfig);
        await global.initializedAppCrypto.init(true);
    }
    return global.initializedAppCrypto;
};

Authentication

All endpoints require these parameters:

{
  "userAuthPayload": {
    "userAddress": "0xYourWalletAddress",
    "signature": "<unique-signature>",
    "message": "<timestamp>"
  },
  "prompt": "Your prompt",
  "nftId": "YourNFTId"
}

userAuthPayload

Get user auth payload using await skynode.appManager.getUrsulaAuth()

Example Implementation

This example demonstrates how to initialize the SDK and interact with the various service endpoints.

import { AIServiceClient } from './services/AIServiceClient';
import express, { Request, Response } from 'express';
import dotenv from 'dotenv';
import cors from 'cors';
import bodyParser from 'body-parser';
// Load environment variables
dotenv.config();

const app = express();
const port = process.env.PORT || 3000;

// Middleware
app.use(cors()); // Add CORS middleware
app.use(bodyParser.json());

// Initialize AI client outside of route handler
const aiClient = new AIServiceClient();

// Initialize AI client when server starts
async function initializeAIClient() {
    await aiClient.initialize();
    console.log('AI Client initialized');
}

app.post('/api/generate-image', async (req, res) => {
    try {
        const { prompt } = req.body;

        if (!prompt) {
            return res.status(400).json({
                success: false,
                error: 'Prompt is required'
            });
        }

        const imageResult = await aiClient.generateAndStoreImage(prompt);

        if (imageResult.success) {
            res.json(imageResult);
        } else {
            res.status(500).json(imageResult);
        }

    } catch (error) {
        res.status(500).json({
            success: false,
            error: 'Internal server error'
        });
    }
});

// Start server
app.listen(port, async () => {
    await initializeAIClient();
    console.log(`Server running on port ${port}`);
});
