Datasets: Used-Car Listings and Hiring Velocity

Datasets and how they are collected

Each page lists the fields, the current figures and how to get a sample.

How a dataset starts

Sign in to Data Works in the Proxies.sx dashboard and choose a dataset. The storefront needs an account. We send a sample cut from the same store as the figures on these pages. You approve the sample and a rate, and only then does anything bill. After that, each finished run downloads as a CSV file. These are the header rows of the two live datasets.

Used-car listings

Collected by Proxies.sx Data Works from public listing pages. Proxies.sx is not affiliated with Seminuevos, Mobiauto or Otomoto. Seminuevos covers Mexico, Mobiauto covers Brazil through dealer stock pages, and Otomoto covers Poland. Each row keeps the listing's asking price, mileage and model year, with the time it was first seen, its latest price change and the time it was removed. Collection started on 19 October 2026, and the samples are partial. The used-car listings page gives price quartiles by model, and the Brazil page covers the largest sample so far.

Hiring velocity

Collected by Proxies.sx Data Works from public career boards. Proxies.sx is not affiliated with Greenhouse, Lever, Ashby or the employers listed. Every day at 06:00 UTC the collector reads each employer's public Greenhouse, Lever or Ashby board and counts open jobs, plus jobs added, closed and reposted since the previous run. The hiring velocity page lists all 40 employers with their open jobs, and the hiring signals page shows how sales and research teams can read the daily changes.

What the public pages show

Public pages show aggregates of at least 10 listings, never individual listings, listing ids, VINs or dealer and seller names. We claim no coverage percentages, and history starts on the collection dates above. The methodology page explains how removals and reposts are counted and how the price statistics are built.

Data from other sites

To collect from a site that is not listed here, see custom Data Works projects, where you send the URLs and fields you need. Managed data compared with a scraping API sets out the cost of running collection yourself, and the e-commerce page covers retail price collection. The open datasets Proxies.sx publishes under CC BY 4.0 are on the research page.
