# AliExpress Product Similar API (https://www.socialcrawl.dev/platforms/aliexpress/product-similar)

> Returns products similar to a source product id, or to a keyword if no product id is passed. 10 per page by default. Product id takes precedence over query when both are set.

TL;DR: `GET /v1/aliexpress/product/similar` costs 5 credits per call and returns SocialCrawl's unified JSON schema. Single x-api-key auth, 100 free credits on signup.

## Parameters

| Parameter | Required | Description |
| --- | --- | --- |
| `product_id` | no | AliExpress product id, the numeric id in a product URL: aliexpress.com/item/3256812847028710.html is product id 3256812847028710. Product ids also come back on every row of GET /v1/aliexpress/search and GET /v1/aliexpress/search/hot. |
| `url` | no | Full AliExpress product URL, for example https://www.aliexpress.com/item/3256812847028710.html. The product id is extracted from the path. |
| `query` | no | Keywords used when no product_id is passed. |
| `page` | no | Page number, starting at 1. Prefer the universal cursor parameter. |
| `page_size` | no | Products per page, 1 to 50. Default 10. |
| `sort_by` | no | Result ordering: price_low, price_high, most_sold, or least_sold. (price_low \| price_high \| most_sold \| least_sold) |
| `country` | no | Ship-to country as a two-letter code. Default US. Changes displayed price and availability. A product that exists for US can return empty for another country. |
| `currency` | no | ISO 4217 currency for displayed prices. Default USD. Live-validated: USD GBP CAD EUR UAH MXN TRY RUB BRL AUD INR JPY IDR SEK KRW ILS THB CLP VND. |
| `language` | no | Copy language as an ISO code. Default EN. Live-validated: EN RU PT ES FR ID IT TH JA AR VI TR DE HE KO NL PL MX CL IN. |
| `max_pages` | no | 1 to 50 (default 1, or 50 when `max_items` or `max_credits` is sent). Walk up to this many pages in one call and return the rows from all of them. Each page walked is billed exactly as one call to this endpoint (a cached page is free) and counts against your rate limit; its charge and any refund are recorded under the page's own request id, listed in `data.walk.request_ids`. The walk stops early at the last page, or when the request's time budget runs low; `data.walk.stopped` says why (`end`, `max_pages`, `max_items`, `max_credits`, `time_budget`, `page_error`) and `pagination.next_cursor` continues from where it stopped. |
| `max_items` | no | 1 to 5000. Get more in one call: keep walking pages until the response holds at least this many rows, then stop with `data.walk.stopped: "max_items"`. The last page is returned whole (it was billed), so `data.items` can hold up to one page more than this, and `pagination.next_cursor` resumes right after it without skipping a row. Walks up to 50 pages unless `max_pages` says fewer; each page is billed as one call (a cached page is free). Add `max_credits` to cap the spend. A long walk can stop on the time budget first (`"time_budget"`): send the returned cursor with the same params to continue. |
| `max_credits` | no | 1 to 100000. The most this call may spend, across every page it walks. A page starts only while the credits already spent plus that page's price (or, when higher, the most any page of this walk has cost) still fit, so the call never goes past it; the walk then stops with `data.walk.stopped: "max_credits"` and the cursor to resume. Sent alone, it walks as far as the budget goes (up to 50 pages). A value below the price of one page is a free 400 whose `error.details.page_credits` names that price. Credits a row join (`include=`) adds are known only once a page has run, so page 1 is checked against its own price. |
