Check a list of ASINs every day and record the price, the list price and whether a deal is running, each with the date it was measured.
Follow the rating, rating count and best-sellers rank of the products you compete with, and see when one starts to climb.
Fill in brand, specs, images, variants and seller for every ASIN in a spreadsheet, without opening a single product page.

| Input | Type | What it does |
|---|---|---|
| subjects * | text list | ASINs or product URLs. 1-10 items |
| marketplace | enum | The Amazon site as its domain suffix , "com", "in", "co.uk", "de"… A product URL carries its own and overrides this; a bare ASIN and a search use it. Prices, stock and reviews differ per site. |
The fields of every row, always present. Nothing is guessed: a value that could not be measured is null, and the answer's coverage says why.

| details | object |
details is always the last field: everything else the source sent for that row, under our own field names. Its keys depend on the source that answered, so read them defensively; it is {} when there is nothing more.
Made-up names and values in the real field names, so you can see the shape before you spend anything.

Pay as you go, in US dollars, per record. No subscription, nothing expires, $5 first top-up, and every new agent starts with $0.10 free.
| Request | Records | At the list price |
|---|---|---|
| One product | 1 | $0.0014 |
| 10 products | 10 | $0.014 |
These are per-record list prices. Some calls also carry a minimum, such as a page of search results, so a small request can cost more than the table shows. The quote ("estimateOnly": true) is free, gives the most your exact request can cost, and the charge then settles to what came back. Records that do not come back are refunded.
One row per product: ASIN, title, brand, price and currency, list price, discount, deal and Prime flags, availability, rating, ratings and reviews counts, best-sellers rank and its category, who sells it, specs, images, variants and the product URL.
Up to ten ASINs or Amazon product URLs per call, and optionally the marketplace. A product URL carries its own site; a bare ASIN uses the marketplace you set.
com, in, co.uk, de, fr, it, es, ca, com.au, co.jp, com.mx and com.br. Prices, stock and reviews differ per site, so the same ASIN can return different numbers on each.
$0.0014 per product at the list price. A small call can carry a minimum, so quote first with "estimateOnly": true: the quote is free and is the most the call can cost. You pay for what comes back, and a product your account already fetched today is served again free.
The playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type.
