Canonical: https://apiforagents.dev/platforms/stockx/product-api · Updated 2026-10-21

Get live StockX market data for up to ten products: last sale, 90-day and 12-month averages, sales counts, bids, and every size's ask, bid and last sale.

- Price: $0.0009 / product
- Billed: Per record
- Free to start: $0.10
- Endpoint: POST /v1/stockx

## What people build with the StockX Product API

- **Price with the market.** 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.

## Quote it, then run it

1. free quote: the exact price, nothing charged:

```bash
curl -X POST https://apiforagents.dev/v1/stockx \
  -H "Authorization: Bearer $AFA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"op":"products","subjects":["https://stockx.com/nike-dunk-low-retro-white-black-2021"],"country":"US","estimateOnly":true}'
```

2. the same call, run:

```bash
curl -X POST https://apiforagents.dev/v1/stockx \
  -H "Authorization: Bearer $AFA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"op":"products","subjects":["https://stockx.com/nike-dunk-low-retro-white-black-2021"],"country":"US"}'
```

## Inputs

Everything you can send in one products call. Required inputs first.

| Input | Type | What it does |
|---|---|---|
| subjects * | text list | 1-10 items |
| country | string | ISO alpha-2 |

## What comes back

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.

| Field | Type |
|---|---|
| slug | string |
| productId | string |
| productUrl | string |
| primaryTitle | string |
| secondaryTitle | string |
| brand | string |
| model | string |
| colorway | string |
| styleId | string |
| category | string |
| subCategory | string |
| categoryPath | string |
| contentGroup | string |
| gender | string |
| condition | string |
| sizeConvention | string |
| retailPrice | number |
| releaseDate | string |
| description | string |
| tags | list of string |
| lastSale | number |
| sales72Hours | integer |
| averagePrice90Days | number |
| sales90Days | integer |
| priceVolatility | number |
| sales12Months | integer |
| averagePrice12Months | number |
| bids | integer |
| askInventoryType | string |
| expressAskCount | integer |
| expressShipLowestAsk | number |
| expressDeliveryDate | string |
| expressLatestDeliveryDate | string |
| images | list of string |
| sizes | any |
| attributes | any |
| lowestAsk | number |
| highestBid | number |
| 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.

## A sample answer

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

| primaryTitle | brand | colorway | category | retailPrice | lastSale |
|---|---|---|---|---|---|
| Stride Runner 90 | Stride | Sea Salt/White | sneakers | 130 | 176 |
| Corvo Court Classic Low | Corvo | Black/Black | sneakers | 110 | 99 |
| Stride Trail Pro GTX | Stride | Moss/Grey | sneakers | 170 | 221 |

## 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 playground](https://apiforagents.dev/dashboard/run?platform=stockx&op=products): 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.

## 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.

## Questions

### 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 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.
