🚀 Usage Examples

Basic Price Lookup

import marketPriceService from "./services/marketPrice.js";

// Get single price
const price = await marketPriceService.getPrice(
  "AK-47 | Redline (Field-Tested)",
  "cs2"
);
console.log(price); // 12.50

Batch Price Lookup (Fast!)

const names = [
  "AK-47 | Redline (Field-Tested)",
  "AWP | Asiimov (Field-Tested)",
  "M4A4 | Howl (Factory New)"
];

const prices = await marketPriceService.getPrices(names, "cs2");
// Returns: { "AK-47 | Redline...": 12.50, ... }

Enrich Inventory with Prices

// When loading Steam inventory on Sell page
const inventoryItems = [...]; // From Steam API

const enriched = await marketPriceService.enrichInventory(
  inventoryItems,
  "cs2"
);

// Each item now has:
// - marketPrice: 12.50
// - hasPriceData: true

Search Items

const results = await marketPriceService.search("AK-47", "cs2", 10);
console.log(results); // Up to 10 matching items

Get Suggested Price (with Markup)

const suggested = await marketPriceService.getSuggestedPrice(
  "AK-47 | Redline (Field-Tested)",
  "cs2",
  1.10 // 10% markup
);
console.log(suggested); // 13.75

💡 Integration Guide

Sell Page - Load Inventory with Prices

// routes/inventory.js
import marketPriceService from "../services/marketPrice.js";

fastify.get("/inventory/:game", async (request, reply) => {
  // 1. Fetch from Steam API
  const steamInventory = await fetchSteamInventory(
    request.user.steamId,
    request.params.game
  );
  
  // 2. Enrich with market prices (FAST!)
  const enriched = await marketPriceService.enrichInventory(
    steamInventory,
    request.params.game
  );
  
  // 3. Return items with prices
  return reply.send({
    success: true,
    items: enriched
  });
});

Admin Panel - Price Override

// routes/admin.js
fastify.put("/items/:id/price", async (request, reply) => {
  const { id } = request.params;
  const { marketHashName } = request.body;
  
  // Get current market price
  const marketPrice = await marketPriceService.getPrice(
    marketHashName,
    "cs2"
  );
  
  // Show admin the current market price
  return reply.send({
    success: true,
    currentMarketPrice: marketPrice
  });
});

Auto-Price New Listings

// When user lists item
fastify.post("/sell", async (request, reply) => {
  const { itemName, game } = request.body;
  
  // Get suggested price with 5% markup
  const suggestedPrice = await marketPriceService.getSuggestedPrice(
    itemName,
    game,
    1.05 // 5% above market
  );
  
  return reply.send({
    success: true,
    suggestedPrice: suggestedPrice || 0.00

🚨 Important Notes

Item Names Must Match Exactly

// ❌ Wrong
"AK-47 Redline FT"

// ✅ Correct
"AK-47 | Redline (Field-Tested)"

Use search() to find correct names:

const results = await marketPriceService.search("AK-47 Redline", "cs2");
console.log(results[0].marketHashName);
// "AK-47 | Redline (Field-Tested)"

Always Check for Null

const price = await marketPriceService.getPrice(name, game);
if (price === null) {
  // Handle missing price
  console.log("Price not found - using fallback");
}

Specify Game When Possible

// ✅ Faster (uses index)
await marketPriceService.getPrice(name, "cs2");

// ⚠️ Slower (searches all games)
await marketPriceService.getPrice(name);
