# That's it. No git clone, no npm install, just works. ✨

What It Does

Transforms complex e-commerce research workflows into natural language:

Why It Matters

• 10x Faster Research: What takes 8-10 hours manually happens in 30 seconds
• AI-Native Interface: Natural language queries instead of complex dashboards
• Production Ready: Rate limiting, retry logic, error handling, monitoring
• Zero-Config Install: One-line npm install, shared API quota, works instantly

🎯 Features

1. Market Research (research_amazon_market)

Intelligent product analysis with A10-F1 grading algorithm.

Key Capabilities:

• Real-time Amazon data via Axesso API integration
• Market grading: A10 (best opportunity) to F1 (oversaturated)
• Multi-layer caching strategy (3x faster responses)
• Sales velocity calculation & revenue estimates
• Competition analysis via BSR tracking
• Advanced filtering: price range, ratings, review count

Technical Highlights:

// Dual caching strategy for 3x performance
Layer 1: Keyword → ASIN mapping (24h TTL)
Layer 2: Master product data per ASIN
Result: 2-5s cached vs 8-15s fresh

2. Keyword Intelligence (research_asin_keywords)

Deep ASIN analysis with opportunity mining & gap detection.

Key Capabilities:

• Multi-ASIN support (analyze 1-10 products simultaneously)
• Keyword metrics: search volume, CPC, competition score, ranking
• Opportunity mining: AI identifies low-competition, high-volume keywords
• Gap analysis: discovers keywords competitors rank for that you don't
• Traffic attribution per keyword

Technical Highlights:

// Parallel processing with Promise.all()
const results = await Promise.all(
  asins.map(asin => fetchKeywordData(asin))
)

3. Supplier Discovery (search_alibaba_suppliers)

Smart Alibaba search with composite quality scoring.

Quality Scoring Algorithm (0-100):

• Trust indicators (40%): Gold Supplier, Trade Assurance, certifications
• Experience (30%): Years in business, transaction history
• Pricing (20%): Competitive rates, flexible MOQ
• Reviews (10%): Rating score, review count, response rate

Advanced Filters: MOQ range, location, certifications, years in business, supplier badges

        "LAUNCHFAST_API_KEY": "lf_your_api_key_here"
      }
    }
  }
}

3. Restart Claude Desktop

4. Test it:

Research the Amazon market for "wireless chargers"

🔧 Technical Highlights

1. Production-Grade Error Handling

Exponential Backoff Retry:

async function fetchWithRetry(url: string, options: RequestInit, maxRetries = 3) {
  for (let attempt = 1; attempt <= maxRetries; attempt++) {
    try {
      const response = await fetch(url, options)

      // Don't retry 4xx errors (client errors)
      if (response.status >= 400 && response.status < 500) {
        return response
      }

      if (response.ok) return response

      // Retry 5xx errors with exponential backoff
      const backoff = Math.pow(2, attempt - 1) * 1000 // 1s, 2s, 4s
      await new Promise(resolve => setTimeout(resolve, backoff))
    } catch (err) {
      if (attempt === maxRetries) throw err
    }
  }
}

2. Defensive Programming

Handles real-world API variance with multiple fallback strategies:

// Multiple fallback field mappings
const name = data.companyName || data.name || data.supplierName || 'Unknown'

// Null-safe number parsing
const moq = parseInt(data.moq?.toString() || '0') || 0

// Array safety
const items = Array.isArray(data.items) ? data.items : []

3. Type-Safe End-to-End

Full TypeScript strict mode with runtime validation:

// Zod schemas for runtime validation
export const MarketResearchSchema = z.object({
  keyword: z.string().min(1),
  marketplace: z.string().default('com'),
  limit: z.number().int().min(1).max(100).default(50),
  useCache: z.boolean().default(true),
  filters: z.object({
    minPrice: z.number().optional(),
    maxPrice: z.number().optional(),
    minRating: z.number().min(0).max(5).optional()
  }).optional()
})

// Type inference
type MarketResearchRequest = z.infer<typeof MarketResearchSchema>

4. Multi-Layer Caching Strategy

// Layer 1: Keyword → ASIN mapping (24h cache)
// Avoids expensive Amazon search API calls

// Layer 2: Master product data per ASIN
// Reuses product details across queries

// Result: 3x performance improvement

5. Security Best Practices

• ✅ User-specific API keys (lf_ prefix validation)
• ✅ Keys in headers, not request bodies
• ✅ Rate limiting with sliding windows (20 req/min)
• ✅ Request audit logging
• ✅ RLS policies for data isolation
