Node.js SDK

Search Amazon

const results = await asa.search.run({
  query: "wireless earbuds",
  domain: "com",
  pages: 3,
  sortBy: "best_match",
});

for (const r of results) {
  console.log(r.position, r.asin, r.title, r.price);
}

Async batch with webhooks

const batch = await asa.batch.create({
  asins: ["B08N5KWBKK", "B0DZ7871B8" /* up to 1000 */],
  domain: "com",
  webhookUrl: "https://your.app/webhook",
});

// Or wait inline
const results = await asa.batch.wait(batch.id, { timeoutMs: 600000 });
console.log(`got ${results.length} products`);

Verify a webhook callback

// Express handler
app.post("/webhook", express.raw({ type: "application/json" }), (req, res) => {
  const valid = asa.verifyWebhook(req.headers, req.body);
  if (!valid) return res.status(400).send("invalid signature");
  const payload = JSON.parse(req.body.toString());
  // ... process payload
  res.sendStatus(200);
});

Run on Cloudflare Workers

// worker.ts
import { Client } from "amazon-scraper-api-sdk";

export default {
  async fetch(req: Request, env: Env) {
    const asa = new Client({ apiKey: env.ASA_KEY });
    const url = new URL(req.url);
    const asin = url.searchParams.get("asin");
    if (!asin) return new Response("missing asin", { status: 400 });
    const product = await asa.products.get(asin);
    return Response.json(product);
  }
};

SDK uses fetch() under the hood, no Node-only APIs. Works on every modern edge runtime.
