Catch property auctions and listings first
Court, tax and public-body auctions are published in official journals that almost nobody reads in time. Get each one as an event, with the organiser, the date and the price, the morning it appears.
For investors, buyers' agents, developers and the tools that serve them.

How it works
From event to action
- An auction is published in the official journal, or a listing appears or drops in price.
- Your agent values it against recent sales and your criteria.
- It shortlists, drafts the questions for the organiser and books the date.
- Permits filed nearby tell it where an area is about to change.
Wake your agents up. Each event can start Claude Code, Codex or your own script the moment it lands, one by one or in batches: no polling, no cron, no dashboard to check.
Events carry text from public sources. Run agents that act on them isolated, with only the access the task needs. Run them safely

About this use case
Which auctions are covered?
Public property auctions in Spain are live (tax, social security and public bodies). Court auctions and more countries follow demand.
Do you cover listings from property portals?
Only where the licence allows; otherwise you connect your own account and those events go to you alone.
What does an auction event include?
The kind of auction, the organiser, the date, the starting and guide price when published, the number of lots and the notice id.
