Embedded Files
listingworks is a one-person data service in Yokohama, Japan. We read the public list pages of classified and job sites once a day and turn them into clean daily files that companies use for market analysis, salary benchmarks and location decisions. We open no individual listing pages, collect no e-mail addresses, telephone numbers or photographs, and remove the names of private individuals.

Poland job postings, daily aggregate counts (Praca.pl): one CSV per day with live, new and removed postings, postings showing pay and the median advertised monthly pay, by voivodeship and by job category. USD 99 per month.
Poland job postings, daily row-level feed (Praca.pl): one row per posting visible on the list pages (title, employer business name, location, employment type, advertised pay, dates, listing URL), with a first-seen ledger and a run log. USD 199 per month.
One-off extract: up to 5,000 listing rows from one public listing site (jobs, property or used cars), delivered within one business day. USD 49.

How we collect
One run per day at a low request rate, respecting robots.txt, without login and without circumventing any access control. Each source site's operator is told in writing what is collected and how it is used; if an operator objects, collection stops that day and stored rows are deleted. Delivered data is licensed for internal use and for publishing aggregates with the credit "Source: listingworks, from public <site> listings"; redistribution of rows is not included.
