const client = new SteamAnalyst("your_api_key");

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

  const { price } = await client.getPrice(name);
  console.log(`${name}: $${price}`);

Find the Cheapest Marketplace

import SteamAnalyst from "steamanalyst";

const client = new SteamAnalyst("your_api_key");
const data = await client.getMarketPrices();

const item = "AK-47 | Redline (Field-Tested)";
const prices = data.markets_prices[item];

const cheapest = Object.entries(prices)
  .filter(([, price]) => price > 0)
  .sort(([, a], [, b]) => a - b)[0];

console.log(`Cheapest for ${item}: ${cheapest[0]} at $${cheapest[1]}`);

Error Handling

import SteamAnalyst, { SteamAnalystError } from "steamanalyst";

const client = new SteamAnalyst("your_api_key");

try {
  const item = await client.getPrice("Nonexistent Skin");
} catch (error) {
  if (error instanceof SteamAnalystError) {
    console.error(`API Error [${error.code}]: ${error.message}`);
    // API Error [ITEM_NOT_FOUND]: Item not found
  }
}

Rate limits depend on your API plan:

| Plan | Rate Limit | Daily Limit | |------|-----------|-------------| | Hobby (Free) | 30 req/min | 100 req/day | | Pro | 300 req/min | Unlimited |

Rate limit info is returned in response headers (X-RateLimit-Remaining). The SDK throws a SteamAnalystError with code RATE_LIMIT_EXCEEDED when you hit the limit.
