Section 16.2: IDX Authorization

Posted by PRO Sat, 25 Mar 2006 13:32:00 GMT

Participants’ consent for display of their active listings by other Participants pursuant to these rules and regulations is presumed unless a Participant affirmatively notifies the MLS that the Participant refuses to permit display (either on a blanket or on a listing-by-listing basis). If a Participant refuses on a blanket basis to permit the display of that Participant’s listings, that Participant may not download or frame the aggregated MLS data of other Participants. Even where Participants have given blanket authority for other Participants to display their listings on IDX sites, such consent may be withdrawn on a listing-by-listing basis as instructed by the seller. Participant’s consent to display of their listings by other Participants is required in order to have their listings transmitted by the MLS to aggregators/publishers of real property ads.

Section 16.4: Accessing IDX

Posted by PRO Sat, 25 Mar 2006 13:46:00 GMT


  1. IDX is available by selecting one of the following two options:
    • Download the IDX database created especially for this purpose through an MLS-approved File Transfer Protocol (FTP) interface (data feed) and place the IDX database on the Participant’s Web site. This option is available to Participants only; however Participants may provide a framed solution to their affiliated Subscribers.

    • Use an MLS-approved framed IDX product such as PRO-IDX or FAR’s IDX


      The following IDX rules apply to both options above.

  2. Participants and Subscribers are prohibited from acquiring access to the IDX database, or any of the information it contains, through methods other than those stated above, including, but not limited to:
    • using the process of "screen scraping"

    • direct links from the MLS system through auto-notification, downloads from the MLS, or other similar technology to extract MLS active listing information from the MLS

    • other Participant’s IDX sites

    • other Web sites on which MLS information may be found. This includes national, regional or local Web sites, whether public or private, with whom the MLS may have contracted for the display of aggregated MLS active listing information.

Section 16.5: Reporting and Monitoring URLs for IDX Sites

Posted by PRO Sat, 25 Mar 2006 13:49:00 GMT

Participants must notify the MLS of their intention to establish an IDX site and must make their site directly assessable to the MLS for the purposes of monitoring and ensuring compliance with applicable rules and policies. Participants must provide the MLS with all URLs that point to their sites.

If Participants choose an FTP download option, Participants (Principal Brokers only) may develop and rebrand their own IDX product to provide to their affiliated Subscribers, provided that data content conforms to these IDX rules. The Participant is required to maintain a list of all of the URL’s where the IDX database appears and to provide a current copy to the MLS.


All Subscriber Web sites used to display the IDX database or any portion of it must be approved by and controlled by the Participant. It is the Participant’s responsibility to ensure Subscriber Web sites conform to these rules, including ensuring the Web sites are properly identified as a real estate brokerage Web site. The Participant is required to notify the MLS of the intention to establish a Subscriber IDX site, to maintain a list of all of the URLs where the IDX database appears, and to provide the MLS with all URLs that point to Subscriber sites.

Note: Web sites must comply with Section 14.22 and 14.23 of MLS Participants standard of Conduct as well as any NAR, FAR or state real estate law.
