Is There an OLX API? Official Options and Car-Data Alternatives

Data: CarDossier database, 1.4M+ Polish market listings, updated daily · Last updated: July 2026

What the official OLX API actually is

The term "OLX API" covers several different things because OLX itself is several different things. OLX-branded marketplaces operate across Europe, Central Asia, and South America, and developer access is organized by region rather than through one global API.

The central hub for OLX Group's European and Central Asian marketplaces is developer.olxgroup.com. Its stated purpose is to let professional users "post and manage adverts" and communicate with OLX users on behalf of their own customers — in other words, it connects CRM, dealer-management, and inventory software to OLX so that professional sellers can publish and update ads programmatically. The hub exposes four API products: OLX (general classifieds), Motors (vehicle marketplaces such as Otomoto.pl and Autovit.ro), Real Estate (including Otodom.pl), and Car Parts. Access starts with a partner application ("Become a Partner"); it is designed for software vendors and professional sellers, not for individual developers who want to query data.

Two points follow directly from that design. First, the official API is write-direction: create ads, update ads, manage messaging and leads. Second, it is gated: you integrate as an approved partner acting for real seller accounts, not as an anonymous API consumer.

Official OLX developer portals by country

Because OLX marketplaces are run by different operating companies, the entry point depends on the country you care about:

If your goal is to publish vehicle ads to Otomoto or OLX Poland from dealer software, the group hub is the correct and only official path. Everything below concerns the other — and far more common — search intent.

What the official Partner API does not do

None of the official portals advertise a public read API. Concretely, there is no documented official endpoint to:

• search or browse listings across the marketplace as a third party;
• export listing datasets (prices, mileage, specs) in bulk;
• query price statistics, trends, or valuations for a make and model;
• monitor competitor inventory or track when cars sell.

That is a deliberate product decision, and it is common across major classifieds platforms: the marketplace data is a core commercial asset, and API access is scoped to what helps sellers list more, not to what lets outsiders read more. If a tool or tutorial promises "the OLX listings API," it is almost always describing either the partner posting API (which will not answer data questions) or an unofficial workaround.

A note on scraping

The usual unofficial workaround is web scraping. As a factual matter: scraping public web pages is technically possible, widely done, and legally unsettled — outcomes depend on jurisdiction, the data involved, and how the access is performed. Most large marketplaces, OLX included, publish terms of service that restrict automated access, and they deploy countermeasures that make scrapers expensive to maintain: markup changes, bot detection, rate limiting, and regional blocking. A scraper that works today is a maintenance liability tomorrow, and the engineering cost of proxies, parsers, and monitoring routinely exceeds the cost of simply buying clean data. We cover this trade-off in depth in our scraper alternative guide. This page does not provide legal advice; if you are evaluating scraping for a commercial product, talk to a lawyer first.

The real question: OLX car market data in Poland

Search intent for "olx api" is scattered across countries and categories, but a large share of it reduces to one need: structured data about cars listed on the Polish market. Poland is one of OLX's biggest automotive markets, the OLX Group also operates Otomoto (Poland's largest car marketplace), and there is no official data product for either. Developers who land here typically want price benchmarks for a buying tool, valuation inputs for a fintech or insurance product, market monitoring for a dealership, or trend data for research.

For that slice of the problem — Polish market, automotive category — an aggregated market-data API answers the question without touching any platform's infrastructure.

CarDossier Market API: aggregated Polish car market data

CarDossier's Market API is built on CarDossier's own database of 1.4M+ Polish market listings, aggregated from publicly available sources and updated daily. It does not proxy, resell, or expose any marketplace's listings; it serves statistical aggregates computed on CarDossier's side: valuation distributions (average, median, P25/P75), monthly price trends up to 24 months back, days-on-market liquidity, prices across all 16 Polish voivodeships, and quantified factors such as import status, transmission, and fuel type.

Honest scoping, so you can rule it out quickly if it is not your use case: it covers Poland only and cars only. It is not a listings feed (no individual ads, no seller contacts) and it will not help you post ads anywhere. If you need Romanian or Ukrainian classifieds data, or non-automotive categories, this API is not the answer.

One credit equals $0.01, so a valuation call costs $0.08. Failed calls are refunded automatically. The API resolves natural vehicle names — "VW Golf", "BMW 3 Series" or "320d", "C-Class", "A4", "XC60" — and every response includes a matched block showing exactly how the input was interpreted. The fuel_type parameter accepts plain English values: petrol, diesel, hybrid, electric, lpg.

OLX Partner API vs CarDossier Market API

These are complements, not substitutes: one publishes ads, the other reads market statistics. Pick by direction of data flow, not by brand.

Quickstart: one call, no key

Every IP gets 5 free demo calls per day against live data — no registration, no credit card, no key. Try it from your terminal right now:

curl "https://car-dossier.com/api/v1/market/valuation?make=BMW&model=3%20Series&year=2019"

The response returns the price distribution for 2019 BMW 3 Series listings on the Polish market, the sample size behind it, and a matched block confirming the resolved make and model. When you outgrow the demo limit, registering with an email OTP (no credit card) grants 50 free credits — enough for six valuation calls or five price-history calls.

Machine-readable and AI-agent access

The API is self-describing for tooling and agents: the OpenAPI spec lives at car-dossier.com/openapi.yaml and an LLM-oriented index at car-dossier.com/llms.txt. For MCP-compatible AI clients, install pip install cardossier-mcp-server (works keyless) or point your client at the remote endpoint https://car-dossier.com/mcp.
