Tradera.com New Auctions & Listings Alert (Sweden)

Search Tradera, Sweden's biggest online auction and second-hand marketplace, for one or more terms and get one flat row per listing: title, price in SEK, buy-now price, listing type, number of bids, start and end date, seller, condition, shipping options, photos and the listing URL. Newest first by default, so a scheduled run is a new-auction alert; the ending-soonest and price sorts make it a bargain and sniping watch.

No account, no login, no browser. One request returns 80 listings.

Input

Field	Notes
queries	One or more search terms, one per line, in Swedish or any language. Required. A listing found by two terms is returned once, under the first.
maxItems	Listings to read per search term (default 100, up to 10,000). Tradera serves 80 per page and stops after 125 pages (10,000 listings), however many it reports finding, so a broader search than that needs a more specific term.
sortBy	AddedOn newest first (default), TimeLeft ending soonest, Relevance, LowestPrice, HighestPrice, MostBids.
proxyConfiguration	Apify proxy by default.

About the sort orders

Each sort was fetched live and its first page checked against the sort it names, on the fields in the rows: AddedOn has start dates descending, TimeLeft end dates ascending, HighestPrice and LowestPrice prices in order, MostBids bid counts descending, and Relevance is Tradera's default order. Tradera has a few more sorts (popularity, bids ascending, prices including shipping); they are not offered because nothing in a row lets you check them.

• The price sorts mix auctions with fixed-price shop listings (item_type ShopItem). LowestPrice starts with shop listings at 1 SEK, so the first rows are rarely the bargains you are looking for.
• Tradera silently ignores a sort name it does not know and answers with the relevance order, so the actor only accepts the six above.

Output

Field	Notes
query	The search term that first found this listing.
position	1-based rank in the order Tradera served for that term, across pages.
item_id, url	Tradera's numeric listing id and the absolute listing URL.
title	The listing title as the seller wrote it.
price_sek	The price right now, in kronor: the top bid for an auction that has bids, the starting price for one without, the asking price for a fixed-price listing.
buy_now_price_sek	The fixed price of an AuctionBin or PureBin listing. null for a plain auction (Tradera sends 0 there; 0 is not a price).
item_type	Tradera's own type, verbatim: Auction (bids only), AuctionBin (bids plus a buy-now price), PureBin (fixed price, time-limited), ShopItem (fixed price from a shop).
total_bids	Bids so far. 0 for a listing nobody has bid on, and always 0 for PureBin and ShopItem.
start_date, end_date	UTC timestamps as Tradera sends them (2026-10-09T19:01:28.1449863Z). ShopItem listings carry an end date years away: a renewal horizon, not a deadline.
is_active	Tradera's isActive flag.
reserve_price_reached	Tradera's reservedPriceReached flag, verbatim. Meaningful for auctions.
open_to_offers	True when the seller accepts offers. null for ShopItem, where Tradera sends no flag.
seller_alias, seller_member_id, seller_is_company, seller_country_code	The seller's handle, member id, company flag and ISO country (Swedish and Danish sellers are common).
category_id	Tradera's numeric category id. The search page carries no category name.
condition	The listing's condition attribute, in Swedish (Oanvänt, Mycket gott skick, Gott skick, Okej skick, Defekt). null when the seller set none.
attributes	One object of every attribute shown on the listing (condition, LEGO series, piece count, ...), a multi-valued one joined with , . The keys depend on the category.
free_shipping	Tradera's free-shipping flag.
shipping_from_sek	The cheapest delivery option in SEK, leaving out pick-up. null when the listing is pick-up only.
shipping_options	Every option Tradera lists as {"type": "PostNordParcel", "cost_sek": 56.0}, pick-up (Takeaway, TakeawayOnly) included.
image_url, image_urls	The main photo (the medium rendition) and every photo URL the search carries: the first two. Nothing is downloaded.
is_promoted, is_highlighted	Tradera's displayPromoted and displayHighlighted flags.

Honest nulls

A field Tradera did not send is null, never 0 or "". The cases you will meet: buy_now_price_sek on plain auctions, shipping_from_sek on pick-up-only listings, condition on listings without one, open_to_offers on shop listings. price_sek is whole kronor in everything seen, stored as a number so the column is one type throughout.

Personal data

Listing text and seller handles are written by private individuals. They are carried as Tradera publishes them, because they are the listing; nothing is extracted from them. You are responsible for handling them under the GDPR if you store them.

Pricing

Pay per event:

• $0.002 per run (actor-start), charged only after your input is validated - a run that fails on bad input costs nothing.
• $0.0007 per listing row written (listing-scraped), i.e. $0.70 per 1,000 listings.

How it fetches

Tradera has no public JSON API. The search page (www.tradera.com/search?q=<term>&sortBy=AddedOn&paging=<n>) is a Next.js app that ships its results inside the HTML, as a JSON object in the page's self.__next_f.push(...) data. The actor decodes that object properly rather than scraping the rendered cards, so every field above comes from Tradera's own structured record.

Things worth knowing, all measured on 2026-10-10:

• Paging. The parameter is paging=<n>. page=<n> is silently ignored and returns page 1 again. Page 1 carries no parameter.
• Result cap. Tradera serves 125 pages of 80 (10,000 listings); a page past the last answers 200 with no listings, and a term with no hits answers 200 with a page count of 0. The run logs when a term was cut off at the cap. totalItemCount stops at 10,000 for a broad term.
• A refusal is a missing payload. The word "captcha" appears on every Tradera page (it is the reCAPTCHA site-key names in the public config) and is not a block signal. A page without the results payload is: the actor treats it, and HTTP 403, 429 and 5xx, as a refusal, rotates to a fresh proxy address and retries.
• Feed order moves while you read it. On the newest-first sort, listings added between two page requests push rows down a page; a row seen twice is returned once.
