Prayk data is open to researchers: how to cite it, and “How Prayk works”
For anyone who wants to use Prayk market indicators in a thesis, a paper or a journalistic investigation, we have opened two new pages: “For researchers” and “How Prayk works”.
Which data is open
- Prayk Index — apartment, rent and car prices by month, with a CSV file.
- Market prices — today’s median prices by brand, model, model year, property type and district.
- District profiles — price per m², rent and gross annual yield.
- Car depreciation by age — the annual rate by model.
- Platform statistics — the number of listings, stores and users by month.
All of these pages are open without registration.
How to cite
The open indicators may be used freely with attribution (CC BY 4.0). The “For researchers” page has a ready-made citation and a BibTeX entry. Three rules:
- give the access date — the current month’s figure changes until the month ends;
- call the figures “asking prices” — they are prices from listings, not transaction prices;
- report the sample size, that is, the number of listings.
What we do not share
Lists of individual listings, phone numbers and other personal data are not shared, even for research. If an indicator is missing from the open tables, write to the address on the page: name the topic and the segment you need, and where possible we will prepare it as a summary table.
How Prayk works
The second page explains the main parts of the system in plain language: where listings come from, how duplicates are found from image and text fingerprints, how search handles the letters of the Azerbaijani alphabet, and how market prices and recommendations are computed. The full price calculation rules are described separately on the methodology page.
