The National Association of REALTORS® introduced IDX MLS Rules over 2 decades ago. In giving these rules they made some parts required and some parts optional. We know the difference.
We always request the IDX Rules from any local Board, Association, or MLS corporation before launching a website in a new location.
API vs RETS
Whether your MLS Vendor uses API or RETS as their preferred method of transferring listing data we can do it! Some Boards are dropping RETS in favor of the newer API transfer standards.
Your clients and visitors won't need to go anywhere else to search and view the listings that are in your MLS. Once they register on your site they can save their searches and choose to be emailed or texted about new listings and price changes.
