Auctionet API
4 of 4 endpoints, ready to run
Search live or archived lots across every auction house on Auctionet, narrowed by country, house and category and sorted by ending time, price or recency. Each row carries the estimate, the starting bid, the current bid, the next valid bid and, for sold lots, the hammer price. Measured 2026-10-01: the unfiltered live set is 38,381 lots and query=rolex returns 31.

How the Auctionet API works
Auctionet is a normal ReefAPI surface — the same four rules that hold for every other engine on the key.
No OAuth app, no request signing, no per-site account. One key covers all 321 engines.
Every route is a POST with a JSON body. Parameters are validated against the published schema before anything is charged.
Credits, not seats. Failed and blocked calls are never charged, and cache hits cost nothing.
One envelope everywhere. meta carries latency_ms, record_count and the endpoint that answered.
Read the currency off the row, because the lot page shows you a converted one
This is the trap that matters on Auctionet. The public lot page prints amounts converted into the visitor's currency, while the underlying data carries the house's original. On one lot the page showed an estimate of 301 with the currency marked USD, and the source gave 3,000 SEK. Deriving the currency from the country, or reading the page, would have published prices off by roughly elevenfold. Every amount here stays in that row's own currency and nothing is converted.
{"locale": "en"}The category tree. A parent id is answered with its children, so take the ids from here rather than assuming.
{"country": "SE"}The houses in that country with their ids and counts, for narrowing to a single auctioneer.
{"query": "rolex", "status": "ended", "country": "SE"}The archive is where the price history lives: the same keyword gives 31 live lots and 1,999 ended ones. Sold lots carry the hammer price.
{"item": "5336678"}The house's own description and condition report for one lot, live or archived.
Lots from hundreds of European houses in one feed, each in its own currency with the estimate, starting bid, current bid and hammer price where they exist, plus the house and category resolvers behind the filters.

}Sweden, Germany and the wider EU, in four currencies, with the archive far larger than the live set
Measured 2026-10-01 against the live gateway: 37 fixed cases run twice at 100%, 50 sampled lots per run for the field counts, plus an independent audit of 150 rows. Two of these lines go against us.
In a 150-row sample the currencies were SEK on 115 rows, EUR on 22, GBP on 10 and DKK on 3. Currency is read from each row, never derived from the country, and no amount is converted.
item_id, url, title, description, condition, house, house_id, category, category_id, currency, estimate_low, starting_bid, ends_at and status were filled on 100% of rows.
current_bid appears once a lot has a bid (60% of a live sample) and is null rather than zero before that; final_bid only exists on sold lots; next_bid disappears once bidding closes. These follow the source and are not filled in.
Auctionet has no by-id surface, so detail works by matching the id inside its own lot and makes a second call for archived lots. Verified on 8 of 8 lots, but it is a match rather than a lookup.
houses is read from the site's own facet panel, which can be shortened. Completeness is only claimed when the counts add up to the total, and that is published as houses_cover_all rather than assumed.
An unknown category_id or company_id is answered by the site with its entire catalogue of 38,672 lots at HTTP 200. Enums are validated before the call, category ids against the live tree, and the returned rows are checked for the requested house and category afterwards.
In 200 archived rows, 168 had sold and 32 had not. The two are separate fields.

Get a free key →What is the Auctionet API?▾
Auctionet API is a ReefAPI endpoint group for auctionet It returns live JSON through POST requests under /auctionet/v1.
Is the Auctionet API free to try?▾
Yes. ReefAPI starts with 1,000 free credits, no card required. Auctionet calls use the same shared credit balance as every other ReefAPI engine.
Do I need an Auctionet login or account?▾
No login to Auctionet is needed for the API response. You call ReefAPI with your x-api-key header, and the playground can run live examples before you create a production key.
How fresh is the Auctionet data?▾
The page example is captured from a live search call, and production requests fetch live data through ReefAPI rather than a static sample.
How many credits does the Auctionet API use?▾
Auctionet actions currently cost 1 credit per successful call. Failed or blocked calls are free. All APIs draw from one credit pool.
Can I call Auctionet from an AI assistant or MCP client?▾
Yes. Connect ReefAPI once through MCP and your assistant can call auctionet actions with the same key, credit pool and JSON envelope used by normal REST requests.
Is the Auctionet API an Auctionet scraper?▾
It is the managed alternative to a DIY Auctionet scraper. Instead of building and maintaining your own scraper — proxies, headless browsers, captcha and constant breakage — you call one ReefAPI endpoint and get the same auctionet back as clean JSON.
Why does my Auctionet scraper keep getting blocked?▾
Most Auctionet scrapers break on anti-bot defenses, rate limits and IP bans that need rotating residential proxies and browser fingerprinting to clear. ReefAPI handles all of that for you — no proxies, no captchas, no maintenance — and returns live JSON. Blocked calls are free.
26 More APIs APIs on the same key
One key, one credit pool, one response envelope. If you are pulling Auctionet, you are one call away from the rest of the category — no second contract, no second integration.
Need something this API does not do?
Name the endpoint, the field, or a source we do not carry yet. We ship new APIs every week and you would be first to get the key. Real people read every message and reply the same day.
Try it on your own data before you pay anything
The call above is the real endpoint, not a recording. A free key gives you 1,000 credits, the other 320 APIs, and the same envelope everywhere.
Endpoints, parameters and credit costs on this page are read from the live catalog and cannot drift from what the API accepts. Field notes were captured on 2026-10-01.
