The Real Estate Transaction Standard (RETS) is a technology used to exchange standardized real estate data between all of the various types of software systems that handle real estate information. RETS is not a program, nor is it a language. It is a framework that can be adopted by any computer system to receive data from the Multiple Listing Service (MLS).
The RETS protocol has served the real estate industry for 20 years. Millions (if not billions) of real estate transactions have used this protocol and to that end it has served the industry well. As can be expected RETS is at the end of its life cycle and is being replaced by a newer standard (RESO Web API) utilizing current technologies.
As RETS is being deprecated we urge all MLS, Brokers and Technology Partners to transition to the RESO Web API as soon as possible.
RESO will keep RETS tools (legacy) available to those who are in transition to our newer standard. RETS Specifications can be found below on this page.

- This EULA has been created and adopted by RESO so End Users understand their rights regarding use of RESO Products.
- Definitions: For purposes of this EULA, the following terms shall have the meanings set forth below.

Except as expressly provided in this EULA, End User may not reproduce, distribute, or display the RESO Product. End User may not use RESO Product to create a derivative work as a technical standard. This EULA is a non-exclusive license, and not a sale, assignment, or exclusive license. RESO retains all rights not expressly granted herein.

Additionally, End User shall display the entire text of this EULA and the following notice: "This document includes works developed by RESO, subject to the RESO End User License Agreement published at www.reso.org." Any software application developed by End User based upon the RESO Products shall include the following notice in its end user documentation and in its codes: "This software product includes software or other works developed by RESO, subject to the RESO End User License published at www.reso.org."
END USER OBLIGATIONS
- No claims. End User agrees that it will not bring any infringement claims based on RESO Product against Members or other End Users for any Intellectual Property End User claims to own that may be included in the RESO Product.
- Indemnification. If End User creates a derivative work or implements the RESO product in such a way that it becomes allegedly infringing, End User agrees to indemnify and hold RESO and Members harmless with respect to any, actions, liability, laws, expenses or legal fees arising from such alleged infringement. RESO or Member shall have the right to participate in the defense and settlement of any action under this section using its own counsel and at its own cost.
- Sole Recourse. End User agrees that End Users sole recourse in the event of any claim, loss, injury, damages, fees, cost, expense, complaint or liability concerning the Stated Subject Matter is to and against only RESO and not to or against any Covered Person nor to or against any other company or person. The "Stated Subject Matter" means any RESO Product, this Agreement and any subject matter of, or any acts or omissions under or arising from, this Agreement. "Covered Person" means any member, licensor, service provider, supplier or contractor of RESO (whether retained by RESO or otherwise involved in the design, development, assembly, offering, marketing, sale, promotion, provision, delivery, support, accessibility, use, quality, performance or availability of any of the Stated Subject Matter). End User agrees to in no event threaten or assert any claim or action against any Covered Person regarding any of the Stated Subject Matter. End User also agrees that each Covered Person shall be entitled to the benefit and protection of any provision of this Agreement that disclaims, excludes, qualifies or limits express or implied warranties, representations, guarantees, promises, remedies, liability or other responsibility to End User or others. End User further agrees that each Covered Person has the right to directly enforce such provisions, and this paragraph, although RESO reserves the right (as between End User and RESO) to also enforce such provisions on behalf of any Covered Person. End User agrees to indemnify RESO and each Covered Person from all claims, losses, injuries, damages, fees, costs, expenses, complaints and liabilities incurred or required as a result of a breach by End User of any of the terms of this paragraph. Each reference in this paragraph to a Covered Person or any other company or person shall be construed broadly and shall include also any affiliate of any of them and any director, officer, equity owner, employee or representative of any of them or of any such affiliate. THIS PARAGRAPH APPLIES NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT.
DISCLAIMERS; LIMITATIONS OF LIABILITY
- Disclaimer of warranties; limitation of liability. IN NO EVENT SHALL RESO BE LIABLE TO END USER FOR ANY INDIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES OF ANY KIND WHATSOEVER ARISING FROM ANY BREACH OF THIS EULA, EVEN IF RESO HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. RESO PRODUCTS ARE PROVIDED "AS IS." RESO AND MEMBERS MAKE NO REPRESENTATIONS OR WARRANTIES EXPRESS OR IMPLIED. RESO AND MEMBERS DISCLAIM ALL REPRESENTATIONS AND WARRANTIES INCLUDING BUT NOT LIMITED TO THOSE OF MERCHANTABILITY, TITLE, AVAILABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT, EXCEPT THOSE EXPRESSLY SET FORTH IN THIS AGREEMENT.

- Survival. Sections 7 through 18 shall survive termination of this EULA.
- Dispute resolution. The laws of the State of Illinois shall govern this EULA and its interpretation. Any action to enforce or interpret this EULA shall have venue in Cook County, Illinois, and the parties hereby submit to personal jurisdiction in that venue.
- Severability. Each provision of this EULA is severable from the whole, and if one provision is declared invalid, the other provisions shall remain in full force and effect. In the event a court having jurisdiction over the parties holds any provision of this EULA invalid or unenforceable, the parties shall negotiate in good faith to replace the invalid or unenforceable provision, if possible, with a valid provision that most closely approximates the intent and economic effect of the invalid provision. If any provision of the limitation of liability or exclusion of warranty is held invalid or unenforceable, this EULA shall immediately terminate unless the parties agree to the contrary.
- Entire EULA. This EULA contains the full and complete understanding of the parties regarding the subject matter of this EULA and supersedes all prior representations and understandings, whether oral or written, relating to the same subject matter.
- No third party beneficiaries. There are no third party beneficiaries of this EULA.
- Relationship of the Parties. The relationship of RESO to End User is that of independent contractor. No party shall be deemed to be the agent, partner, joint venturer, franchisor or franchisee, or employee of RESO or have any authority to make any agreements or representations on the behalf of RESO.
- E-notices. All notices, disclosures, and other communications made between RESO and End User electronically satisfy any legal requirement that such communications be in writing.
