How the Njuškalo + Bolha API works
Njuškalo + Bolha 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 491 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.
From a category to a dated price list with every car's details
Find the category, filter it the way the site does, page through, then read the listings that matter.
Every car make with its live listing count; the slug goes into browse.
Rows with price, year, mileage, fuel and power from the card, location and seller. available_filters lists the category's own filter names.
Add any of the category's filters and page until has_more is false (page 400 at most).
Every detail field, equipment, description, photos, coordinates, view count, expiry date and the seller's profile.
A dated feed of Croatian or Slovenian listings with euro prices, the category's own facts and the private or business seller behind each one.

}What a Njuškalo / Bolha field actually contains
Fields that read differently from how they look. Every row was measured against live njuskalo.hr and bolha.com pages on 2026-10-14.
| Field | What it holds |
|---|---|
| listing_id | The number after -oglas- in the listing's web address. Pass it unchanged to listing (a listing URL works too). Search to listing returned the same id, price and seller on 22 of 22 rows across both sites. |
| price, price_text | price is the asking price in euros as a number; price_text is the site's own string ("14.400 €", "350.444,50 €": the dot groups thousands, the comma marks cents). On 16 of 16 listing pages price matched the price printed on the page. |
| price_on_request | true when the seller asks to be contacted for the price; price is then null rather than 0. A listing priced "0 €" also gets price null, with the string kept in price_text. |
| is_promoted | Paid promoted listings (up to 6) shown above the regular results on page 1. The site picks a different set of promoted listings on each request, so they are flagged and counted separately; the 25 regular rows are stable. |
| seller.seller_type | private or business on search rows, as the site labels the seller; listing adds store for registered shops, agencies and developers. |
| attributes | The key facts the site prints on the card for that category: year, mileage, fuel and power for cars, m² and year built for flats, memory and condition for phones. |
| total, last_reachable_page | total is the site's own count of matching listings. The site serves at most 400 pages of 25 (10,000 rows) per query even when it reports more pages; last_reachable_page says where the results stop. |
| available_filters | On browse: the category's own filters with their parameter names and choices, as the site defines them. Pass any of them in filters; a name the category does not have is refused rather than silently ignored. |
Prices and listings were identical when read from Croatia, Germany and the United States on 2026-10-14 (same listing, same regular rows). Category pages beyond their last page are reported as empty with page_clamped: true; the site itself would send you back to page 1.
Njuškalo and Bolha coverage, measured
Every number below was read from live njuskalo.hr and bolha.com responses on 2026-10-14, in four runs of 93 calls each; the last run answered 92 of 92 calls as expected.
Croatia (njuskalo.hr) and Slovenia (bolha.com), prices in euros. On njuskalo "golf" matched 105,453 listings, "bicikl" 31,092, the auti category 53,787 and flats for sale 50,635; on bolha "kolo" 17,329 and spare parts 311,920.
"bicikl" 31,092 → one category 553, 100 to 300 € 6,383, new 12,880, used 14,806, title only 11,193, buyer-protected payment 8,479. Cars 53,787 → private 17,744 + business 36,043, 2018-2020 11,087, up to 50,000 km 9,935.
Title, link, photo, location, date and seller type on every row; price on 21 of 24 sampled pages for every row (the others had on-request or 0 € listings); condition on all regular rows of item categories, not used for real estate.
The listing price matched the price printed on the listing page on 16 of 16 listings and the page's structured data on 15 of 15. Search to listing: same id, price and seller on 22 of 22.
At most 400 pages (10,000 rows) per query; phone numbers only where the seller wrote them into the description; seller pages, map-radius search and the jobs section are not covered; expired listings return NOT_FOUND.

The questions people actually ask before wiring up Njuškalo + Bolha.
Get a free key →Do I need a Njuškalo or Bolha account?▾
No. Everything is read logged out, and you call reefapi.com from anywhere.
Does it cover Slovenia as well as Croatia?▾
Yes. site=hr reads njuskalo.hr and site=si reads bolha.com; the two sites share one platform, so the fields are the same. Bolha's car category has no private-or-business filter, and the API says so instead of returning the unfiltered list.
Can I filter cars by year, mileage and fuel?▾
Yes, with browse on a car category and the site's own filter names. On 2026-10-14 the auti category had 53,787 listings: 2018 to 2020 left 11,087, up to 50,000 km 9,935, diesel 32,513, private sellers 17,744 and business sellers 36,043.
Can I separate private sellers from dealers and agencies?▾
On category pages, yes: seller_type private or business, and the two add up to the category total. Every row also carries the seller's type, so you can split a keyword search yourself.
How deep can I page?▾
Up to page 400 of a search or category, which is 10,000 rows; the site stops there even when it reports more. Narrow by category, price or filters to reach the rest.
Do you return the seller's phone number?▾
Only where the seller wrote it into the description. The site shows phone numbers to logged-in users, and this API reads the logged-out site.
What happens with a sold or expired listing?▾
listing returns NOT_FOUND. Expired listings stay online as a stub without price, and the API reports them as no longer active.
Which categories exist?▾
Call categories without a category for the top level, then with a path such as auti, prodaja-stanova or avto-moto for its children, each with its live listing count. Use the slug in browse and the category_id in search.
What is the Njuškalo + Bolha API?▾
Njuškalo + Bolha API is a ReefAPI endpoint group for croatia's and slovenia's biggest classifieds: cars, flats, phones and everything second-hand, with price, details and seller. It returns live JSON through POST requests under /njuskalo/v1.
Is the Njuškalo + Bolha API free to try?▾
Yes. ReefAPI starts with 1,000 free credits, no card required. Njuškalo + Bolha calls use the same shared credit balance as every other ReefAPI engine.
Do I need a Njuškalo + Bolha login or account?▾
No login to Njuškalo + Bolha 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 Njuškalo + Bolha 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 Njuškalo + Bolha API use?▾
Njuškalo + Bolha actions currently cost 2-3 credits per successful call. Failed or blocked calls are free. All APIs draw from one credit pool.
Can I call Njuškalo + Bolha from an AI assistant or MCP client?▾
Yes. Connect ReefAPI once through MCP and your assistant can call njuskalo actions with the same key, credit pool and JSON envelope used by normal REST requests.
231 E-commerce & Marketplaces APIs on the same key

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 490 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 2026-10-14.
