Getting Started

1. Get your API key

Create an account and generate a FetchLayer API key from your dashboard. There is no AliExpress affiliate program to join and no open-platform app key to request.

2. Search in a pinned market

curl -X POST https://api.fetchlayer.dev/aliexpress/search-products \
  -H "Authorization: Bearer ss-your-key" \
  -H "Content-Type: application/json" \
  -d '{"query":"mechanical keyboard","shipTo":"US","currency":"USD","language":"en_US"}'

One page is 60 products, each with its productId, price and original price, discount, rating, sold count, ship-from country and category id. The response echoes the market it was read in. Currencies USD, EUR, GBP, CAD, AUD, NZD, BRL, MXN, CLP, COP, PEN, ARS, JPY and KRW, and languages en_US, de_DE and pt_BR are accepted; anything else is a 400.

3. Check prices in one request

curl -X POST https://api.fetchlayer.dev/aliexpress/product-prices \
  -H "Authorization: Bearer ss-your-key" \
  -H "Content-Type: application/json" \
  -d '{"products":["1005009494458560","1005006994630464"],"shipTo":"US","currency":"USD"}'

Up to 20 products per request, each back in request order with its own status: ok, unavailable, not_found, or failed — which means check that one again later. Pass { "product": "…", "skuId": "…" } to track one variant; the skuIds are on /product-details.

4. Follow the reviews

curl -X POST https://api.fetchlayer.dev/aliexpress/product-reviews \
  -H "Authorization: Bearer ss-your-key" \
  -H "Content-Type: application/json" \
  -d '{"product":"1005009494458560","sort":"latest","shipTo":"US","language":"en_US"}'

Twenty reviews per page with the star distribution, each with the text translated into your language and the reviewer's original words, country, the variant bought and any seller reply. Many AliExpress reviews are a rating with no text.
