Breaqs listing data for your own websites (developer reference)

As well as the ready-to-use listing widget, as a developer you can also work directly with the underlying JSON files to build a completely customised view – for example, if you want to integrate the listings into an existing CMS theme or build your own search/filter experience.

All the endpoints listed below are publicly accessible (no API key is required apart from what's already included in the URL) and include CORS headers, so you can call them directly from browser JavaScript without needing your own backend proxy.

1. List of offers

GET https://breaqs.com/public_json/dealers/{dealerid}/{public_api_key}_list.json

You can find your dealer ID and public key on your Breaqs dashboardApi access

Returns an array containing one object per advert:

field type description

adid number unique advert ID
catid number main category – see (3. Lookup tables)
brand string Brand / Category name
model string Model / Category name
typeoffer number 1 = auction, 2 = fixed price
brandid, modelid number numeric make/model IDs (name lookup not yet available; see limitations)
title string advert title
tagline string brief summary
imgurl string URL of the main image (thumbnail size)
price string price without a currency symbol, e.g. ‘24950.00'. ‘0.00' means: no bid yet (in an auction) or price on request (for a fixed price)
currency string ISO currency code, e.g. ‘EUR'
timeleft number | null for auctions only: the Unix timestamp (in seconds) at which the auction ends
detaillink string link to the full advert on breaqs.com
buildyear string year of manufacture
color, transmission, fuel, bodywork string numeric IDs, resolved via the lookup table
doors string number of doors
milage string mileage

Please note: fields that are empty in an advert are completely missing from the JSON (no null/empty string), so build defensively and check for presence, not just for an empty value.

2. Vehicle Advertisement Details

GET https://breaqs.com/public_json/dealers/{dealerid}/listing_{adid}.json

Returns a single object (not an array) containing all the fields from the list, plus:

field type description

power string power, unit is in kwhp see below
kwhp string unit of power, e.g. ‘kW'
weight string weight; unit given in kglbs – see below
kglbs string unit of weight, e.g. ‘kg'
milage string mileage, unit shown in kmmls
kmmls string unit for mileage, e.g. ‘km'
displacement string engine capacity in cc
cylinder string number of cylinders
motvalid string the year until which the MOT/vehicle inspection is valid
euroemis string emission class as ready-made text, e.g. ‘Euro 3'
co2emis string CO₂ emissions as ready-made text, e.g. ‘123 g/km'
description string formatted HTML (already filtered by Breaqs) – see explanation below
photos array see below

Photos

"photos": [ { "large": "https://cdn.breaqs.com/.../foto1_n.webp", "small": "https://cdn.breaqs.com/.../foto1_s.webp" } ]

Each photo has a small (thumbnail) and a large (full-size) version. For adverts with a large number of photos (up to ~100), we recommend pre-loading only the small versions and only fetching the large versions once the visitor actually views that photo.

The “description” field contains formatted HTML!

This field contains the text as entered by the dealer, already filtered by Breaqs' own HTML Purifier and strip_tags filter - only 'p', 'u', 'em', 'strong', 'ul', 'li' and 'br' are allowed through; all other unwanted formatting is removed. Nevertheless, we recommend that you sanitise this HTML locally once more in your own view before displaying it via innerHTML (e.g. using DOMPurify) - not because you should distrust Breaqs' filtering, but as a standard defence-in-depth measure: as a general rule, you should always sanitise content that you haven't created yourself and are rendering directly as HTML once more on your own side.

3. Lookup tables

GET https://breaqs.com/public_json/widget/widget_lookups_{lang}.json

Supported languages: cs, de, en, es, fr, it, nl, pl.

Converts the numeric catid, colour, transmission, fuel and bodywork values into readable labels, by category:

{ "1": { "id": "cars", "color": { "16": "black", "2": "blue" }, "transmission": { "1": "Manual", "2": "Automatic" }, "fuel": { "1": "Gasoline" }, "bodywork": { "2": "stationwagen" } } }

Not every category has the same fields – boats, for example, do not have ‘bodywork' or ‘transmission'. So always check whether a field exists before you try to resolve it.

Known limitations

  • Advertisements that have been sold can remain up to 48 hours in the list so that interested parties can still get in touch.
  • Brand and model names are already included as plain text in the JSON; a separate lookup is no longer required for this (+ api version 1.14+).
  • The files are updated periodically; please allow for a delay of 1 to 2 hours before any changes become visible.
