# Klarna Category API (https://www.socialcrawl.dev/platforms/klarna/category)

> Returns products in a Klarna category, 48 per page by default, each with product id, title, lowest price, rating, and image. Pagination is clean: page 2 of Headphones had 24 new ids and zero overlap with page 1. Feed a category id from GET /v1/klarna/categories.

TL;DR: `GET /v1/klarna/category` 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 |
| --- | --- | --- |
| `category_id` | yes | Klarna category id, for example cl94 for Headphones or t1 for TV and Audio. Ids come from GET /v1/klarna/categories and from search rows as category.id. Required for GET /v1/klarna/product when you pass product_id instead of a shopping URL. |
| `region` | no | Shopping region: usa (default), uk, germany, sweden, france, italy, spain, netherlands, austria, ireland, norway, finland, denmark. Changes currency, language, and the merchant set. (usa \| uk \| germany \| sweden \| france \| italy \| spain \| netherlands \| austria \| ireland \| norway \| finland \| denmark) |
| `size` | no | Products per page, 1 to 100. Default 48. |
| `offset` | no | Row offset, starting at 0. Prefer the universal cursor parameter. |
| `sort_by` | no | Result ordering: popularity (default), price_low, price_high, trend, name, rating, or price_drop. (popularity \| price_low \| price_high \| trend \| name \| rating \| price_drop) |
| `price_range` | no | Price filter as min-max, for example 50-500, or 50- for 50 and above. |
| `filter` | no | Facet filter as keyID-valueID from GET /v1/klarna/category/filters. |
| `category_path_id` | no | Sub-category path id as keyID-valueID. |
| `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. |
