ASIN402

Watch Amazon ASINs: scheduled price, buy box and stock checks with change alerts. Pay once to monitor 1-50 ASINs every 1h, 3h, 6h, 12h or 24h for 1-30 days. Each check records buy box, Amazon, lowest new/used price, stock, buy box seller, offer count, sales rank and rating, and logs changes as events (price drops/rises, out of stock, back in stock, buy box seller change, below your target price).

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://asin402.com/api/watch", { method: "GET" });
console.log(await res.json());
