x402 Use Case: Premium recommendations, batch discovery, integration assistance

Installation

npm install @nirholas/x402-ecosystem @nirholas/tool-discovery-mcp

Integration Pattern

import { PaywallBuilder, PricingStrategy } from '@nirholas/x402-ecosystem/premium';
import { ToolMarketplace } from '@nirholas/x402-ecosystem/marketplace';
import { ToolDiscovery } from '@nirholas/tool-discovery-mcp';

// Discovery pricing
const discoveryPricing = PricingStrategy.fixed({
  'basic-search': 0,            // Free: basic search
  'deep-analysis': 0.05,        // $0.05: detailed tool analysis
  'ai-recommendations': 0.10,   // $0.10: AI-powered recommendations
  'compatibility-check': 0.02,  // $0.02: compatibility analysis
  'batch-discovery': 0.25,      // $0.25: discover tools for use case
  'integration-guide': 0.15,    // $0.15: generate integration guide
  'monitoring': 2.00            // $2/month: new tool alerts
});

const discovery = new PaywallBuilder()
  .service('tool-discovery-mcp')
  .pricing(discoveryPricing)
  .build();

Discovery Methods

// Free: Basic search
async function searchTools(query: string) {
  return ToolDiscovery.search(query, {
    sources: ['mcp-registry', 'github', 'npm'],
    limit: 10
  });
}

// Premium: Deep analysis
async function analyzeToolDeep(toolId: string) {
  await discovery.charge(0.05, { type: 'deep-analysis', tool: toolId });

  return ToolDiscovery.analyze(toolId, {
    readme: true,
    apiStructure: true,
    dependencies: true,
    securityAudit: true,
    usageExamples: true,
    maintenance: true,     // Last update, issue response time
    communityHealth: true  // Stars, forks, contributors
  });
}

// Premium: AI recommendations
async function getRecommendations(context: AgentContext) {
  await discovery.charge(0.10, { type: 'ai-recommendations' });

  return ToolDiscovery.recommend({
    currentTools: context.installedTools,
    useCase: context.primaryUseCase,
    preferences: {
      prioritize: ['security', 'performance', 'ease-of-use'],
      avoid: context.blacklistedTools,
      budget: context.monthlyBudget
    }
  });
}

Marketplace Integration

import { ToolMarketplace } from '@nirholas/x402-ecosystem/marketplace';

// Sync discovered tools with marketplace
const marketplace = new ToolMarketplace({
  network: 'eip155:42161',
  registryAddress: '0x...'
});

async function syncDiscoveredTools() {
  // Discover new tools
  const newTools = await ToolDiscovery.findNew({
    since: Date.now() - 24 * 60 * 60 * 1000, // Last 24h
    minStars: 10,
    categories: ['crypto', 'defi', 'blockchain']
  });

  // Register in marketplace
  for (const tool of newTools) {
    const analysis = await ToolDiscovery.analyze(tool.id);

    await marketplace.registerTool({
      id: tool.id,
      name: tool.name,
      description: analysis.summary,
      category: analysis.category,
      pricing: analysis.suggestedPricing
    });
  }

  return { registered: newTools.length };
}

Batch Discovery

import { PayableAgent } from '@nirholas/x402-ecosystem/agent';

const agent = new PayableAgent({
  wallet: agentWallet,
  approvedServices: ['tool-discovery-mcp'],
  dailyLimit: 10
});

// Discover all tools for a use case
async function discoverForUseCase(useCase: string) {
  await agent.pay({
    service: 'tool-discovery-mcp',
    amount: 0.25,
    description: `Discover tools for: ${useCase}`
  });

  return ToolDiscovery.discoverForUseCase(useCase, {
    depth: 'comprehensive',
    includeAlternatives: true,
    compareFeatures: true,
    recommendStack: true
  });
}

// Example output
const defiTools = await discoverForUseCase('defi trading bot');
// Returns: 
// - Core tools: swap, price feed, portfolio tracker
// - Optional: alerts, analytics, social signals
// - Recommended stack with pricing

Compatibility Check

// Check tool compatibility
async function checkCompatibility(toolId: string, environment: Environment) {
  await discovery.charge(0.02, { type: 'compatibility-check' });

  return ToolDiscovery.checkCompatibility(toolId, {
    nodeVersion: environment.nodeVersion,
    mcpVersion: environment.mcpVersion,
    existingTools: environment.installedTools,
    platform: environment.platform,
    // Returns: compatible, conflicts, required updates
  });
}

Integration Guide Generation

// Generate integration guide for a tool
async function generateIntegrationGuide(toolId: string, context: ProjectContext) {
  await discovery.charge(0.15, { type: 'integration-guide' });

  return ToolDiscovery.generateGuide(toolId, {
    projectType: context.projectType,
    existingStack: context.stack,
    preferredLanguage: context.language,
    format: 'markdown',
    includeExamples: true,
    includeTests: true
  });
}
