Best sneaker price API: six options compared

The short answer by use case

• The price for the pair in a scanned box: Barcodes.gg. One call goes from barcode to size to price.
• StockX and Alias prices with product data from the same token: Barcodes.gg.
• The lowest price per call, live StockX and GOAT prices and sales history: Packet. €29 buys 50,000 credits.
• A former KicksDB user: KicksDB takes no new sign-ups, and Packet is its successor. The KicksDB alternative page has an endpoint map.
• GOAT prices with the last sale per size and an EU landed cost: SoleFetch. Its documentation needs a login.
• Your own StockX or Alias listings and orders as a seller: the official StockX API or the official Alias seller API.
• StockX prices without a StockX seller account: see the StockX API alternative page.

Barcodes.gg

Barcodes.gg is a barcode and product data API for sneakers and streetwear, run by Reactive Systems SL. Since 25 October 2026 it also returns resale prices per size. Send a style code, or send a barcode to get the prices for the size of that barcode only. Rows come from StockX and Alias (GOAT Group). Each price has its own time, and is_stale marks an answer older than 24 hours. Request parameters choose the sites, the StockX currency, up to 3 StockX markets, the Alias region, consignment and freshness. The documentation lists every allowed value.

Prices are on Standard Plus (€79 per month, 10,000 calls) and higher plans. One answered request uses one call, and a product without cached prices is not charged.

Where it is weaker: it covers two marketplaces, StockX and Alias. It has no GOAT source, no sales history endpoint and no free tier for prices. It also costs more per call than Packet or SoleFetch Pro. Details are on the sneaker resale price API page.

KicksDB

KicksDB (kicks.dev) no longer accepts new sign-ups. A Packet blog post of 21 October 2026 says so and names Packet as the successor from the same team. Since July 2026, the Packet data layer serves the KicksDB StockX and GOAT data. kicks.dev did not answer on 25 October 2026. On 26 October 2026 it answered again, with its old price table and a banner for pckt.sh. Its documentation still says that sign-ups moved to Packet.

The KicksDB documentation lists StockX with a refresh of 4 hours in the US and 24 hours in the EU, GOAT, Flight Club and Shopify shops. It lists a GTIN lookup, batch prices for 50 products, sales history for the US and DE, and events on the Pro plan. A snapshot of kicks.dev from 15 May 2026 shows Starter at €29 per month for 50,000 requests. The KicksDB alternative page has a map from KicksDB v3 features to Barcodes.gg endpoints.

SoleFetch

An earlier version of this page, published on 25 October 2026, said that SoleFetch returns one average price. That was wrong. Its home page shows prices per size.

SoleFetch (solefetch.com) names "GOAT and other platforms" as sources, and its samples carry "market_type": "Alias/GOAT". Lookups work by style code, by UPC (/v1/scan/{code}), by slug and by keyword. A size listing has lowest_price, highest_offer and last_sold_price. A GOAT listing call takes region=EU and returns a total price with import duties, VAT and shipping. It also has market scores and a release calendar.

Plans: Free with 100 calls per month, Basic €19 for 3,000 calls, Pro €49 for 25,000 and Elite €99 for 250,000. Rate limits run from 20 to 300 requests per minute.

Where it is weaker: the documentation needs a login, the terms and privacy pages answered 404, and the site names no company. The samples show no timestamps and US sizes only. We could not verify StockX as a source, or whether the UPC scan returns prices for the scanned size. The SoleFetch alternative page compares it with Barcodes.gg.

Packet (pckt.sh)

Packet (pckt.sh) is the KicksDB successor, from the same team. It sells credits: Free with 500 credits per month, Developer €29 for 50,000, Business €99 for 150,000 and Scale €379 for 600,000. A live StockX, GOAT, Alias or Flight Club call costs 1 credit, and a cached catalog call 0.3 to 0.4 credits.

Live StockX and GOAT calls take countryCode and currencyCode, with a cache of 5 to 30 minutes. Cached data can be up to 24 hours old. It has sales history, lists of asks and bids, batch cached prices and datasets. Each endpoint covers one marketplace. It returns GTINs but takes none as input. The Packet alternative page compares it with Barcodes.gg.

Retailed.io

Retailed.io sells scraper APIs by data source, with credits. Its EUR pricing page shows Premium at €49 per month for 18,000 credits, up to Startup at €229 for 110,000. StockX endpoints cost 2 credits, and the free trial gives 50 credits once. It lists StockX, GOAT and Stadium Goods. Its StockX product call takes country and currency and returns the lowest ask, highest bid and last sale per size. Each endpoint covers one marketplace. We could not verify a barcode to price lookup or its refresh times.

StockX API and Alias seller API (official)

StockX publishes its own API at developer.stockx.com. It is the official StockX API for sellers. Use it when you sell on StockX and work with your own account. The StockX API alternative page compares it with the Barcodes.gg price API.

Alias also has an official seller API for its own sellers. Its documentation lists catalog, pricing insights, listing and order functions, with personal access tokens. Barcodes.gg gives Alias prices by style code or barcode without an Alias account.

The price data APIs on this page do not replace these seller APIs, and none of them is a StockX or Alias partner.

How to choose: test your own products

1. Collect 20 style codes and, if you scan stock, 20 barcodes from the products you handle.
2. Send the same list to each candidate on its free tier, trial or lowest plan.
3. Count the products with a price. Check the marketplaces, the sizes and the time on each price.
4. Work out the monthly cost at your real volume, with the plan you would need.

Barcodes.gg does not charge a request for a product without cached prices, so a miss costs nothing.

How this comparison was made

Every competitor figure was read on the vendor site, documentation or public OpenAPI file on 25 October 2026. The sources are listed under the table. kicks.dev did not answer that day, so KicksDB figures come from docs.kicks.dev and a Wayback Machine snapshot of kicks.dev dated 15 May 2026. kicks.dev answered again on 26 October 2026, and we added its status on that date. Prices are in the currency of each vendor and are not converted. Plans change, so check the vendor site before you buy. This page shows no match rates, speed figures or review scores, because we did not measure them. KicksAPI, the RapidAPI listings and the open-source Sneaks-API are not in this comparison.
