Where the data comes from

OpenBidMap lists bids published by public agencies. We collect the listing details (title, agency, location, dates, link) from the public pages and data feeds below, extract a few facts from the public notice text where we can read it, and always link back to the official notice. We don't host plans or bid documents.
