What people build with the StockX Product API

Read the last sale, lowest ask and highest bid before you buy or list, size by size.

Spot demand

Sales in the last 72 hours and the 90-day average show which products are moving and which have cooled.

Portfolio valuation

Value a collection or an inventory at today's market prices, with the date each was measured.

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 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.

A sample answer

Made-up names and values in the real field names, so you can see the shape before you spend anything.

Pricing

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	$0.0009
10 products	10	$0.009

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.

Try it without writing code

Open the StockX Product API in the playgroundThe 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.

Why this one, and not a scraper you run yourself

No login, no StockX account, no cookies, no proxies, no browser to babysit.
When the site changes its pages, your request stays the same: keeping the reads working is our job, not yours.
A fetch that fails costs nothing: it is named in the answer with a reason, and the quote says the most a call can cost before it runs.

Use it from your tools

Questions people ask.

What does the StockX Product API return?

One row per product: title, brand, colourway, category, retail price, last sale, lowest ask, highest bid, sales in the last 72 hours, 12-month average price, slug, style id, release date, product id and URL, and images, plus 90-day figures and every size's ask, bid and last sale.

What do I pass in?

Up to ten StockX product URLs or slugs, and optionally a two-letter country code.

How much does it cost?

$0.0009 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.

Why people pick API for Agents

One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
$0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
Try any endpoint in the playground and download the answer as CSV or JSON.
