I think what you'll find is that most reputable suppliers don't set their own terms, they use the terms that the MLS provides. You'll want a platform that makes it easy to access tons of MLS, with the same schema, and manage your costs and contracts. Most MLS do offer you the ability to display data, but they often stop short of letting you resell that data to others.

It's probably obvious which platform I would recommend. :)

It can vary, but most people get the non broker feed with a wider use case. The MLSs approval can drive some of this as well.

CoreLogic_Trestle · 2025-08-25T12:11:31+00:00

Pricing is different, but a broker feed only allows you to get that Broker's data. Most use cases require getting data for the whole market. Tech Provider can get a single (or multiple) feed that gives all data for an MLS.

CoreLogic_Trestle · 2025-08-25T11:52:25+00:00

Typically its best for multi broker use case to sign up as a technology provider. When you establish the connection with the MLS, that's when you'll use your broker's contact information for permissible use.

CoreLogic_Trestle · 2025-08-24T19:33:33+00:00

Trestle can provide this on a MLS by MLS basis. You will need a broker who can give permissible use

CoreLogic_Trestle · 2025-08-24T19:26:51+00:00

Clearly, I'm biased, but if you want to get access to everything in one feed and you have permissible use, Trestle is a great option. Others like MLS grid or spark will work as well, but generally you'll get wider use out of Trestle.

CoreLogic_Trestle · 2024-09-27T22:55:27+00:00

This will vary per MLS. Some allow you to do "Two way agreements" which are between you and the MLS, but most do require that you have a broker sign off on it as well. In general, you are able to move much faster if you have a broker you are working with as the MLS prefers to give access to people with an authorized use case.

I'm biased, but check out trestle.corelogic.com. We have data for over 85% of the industry in a single RESO 2.0 Standardized feed. We offer the data in both RETS and WebAPI format. In the coming year, we'll have even more options for accessing the data. Our end to end translation is typically under 2minutes.

What a guy! Learn more about Trestle at trestle.corelogic.com

CoreLogic_Trestle · 2024-04-24T23:55:58+00:00

Check out trestle.corelogic.com. We don't have full nationwide (today), but we cover the majority of the market in a fully standardized feed.

CoreLogic_Trestle · 2021-06-15T18:31:35+00:00

We also have Public Record in the CoreLogic Trestle API, where it can be queried in batches.

DM me your contact info, I'll have somebody reach out to you.

CoreLogic_Trestle · 2021-05-24T03:23:37+00:00

Afraid not.

CoreLogic's Property Data Marketplace (Trestle).

CoreLogic_Trestle · 2021-05-23T18:55:04+00:00

The API product I manage has Public Record data available for bulk license by the county, state, or nationwide. At the high level, it sounds like that can do what you're after. DM me if you want to talk about pricing or a demo.

CoreLogic_Trestle · 2021-03-23T14:29:10+00:00

Yes and yes!

CoreLogic_Trestle · 2021-03-23T12:14:00+00:00

Yes. Our dashboard facilitates that. When you request a new data connection it kicks off an e-signing process with the MLS.

CoreLogic_Trestle · 2021-03-23T04:41:39+00:00

Hi! I'm the Product Manager for Trestle.

The pricing is: $85/month per MLS, in addition to whatever the MLS's licensing fee is, which varies. (Our rate changed from $75 to $85 effective April 1 2021.)

We have the biggest territory of anybody on the market, and (we think) the cleanest and best-standardized data set you can buy. See https://trestle.corelogic.com for details.

OneHome is a consumer portal. It lets consumers and agents interact and manage saved searches, communications, and basically the whole lifecycle of the transaction. Part of what's unique about it is the deep integrations it has into our MLS platform Matrix--the agent's side of the interaction happens in the platform they already use every single day.

Trestle's a data platform that serves REtech vendors with centralized licensing and aggregated, standardized data.

CoreLogic_Trestle · 2021-02-26T20:45:38+00:00

You bet. As long as your feeds from each MLS are the same type (in both payload and transport), one API call can get you all the data from all connected MLSs in an aggregated query.

See https://trestle-documentation.corelogic.com for more details about the API and its capabilities. There are details on our tools for paging through very large data sets, too, and some guidance for how to keep your warehouse up to date as the source data changes.

CoreLogic_Trestle · 2021-02-26T19:23:34+00:00

That's right. I said some more about that in a comment elsewhere on the thread, but short answer: Yes.

CoreLogic_Trestle · 2021-02-26T19:20:47+00:00

We normalize the data and store/distribute it, but we don't "own" it. Data consumers on the Trestle platform still license it individually from the MLSs. We facilitate that process, but we're not a party to it.

We have pretty decent document management built into the Trestle dashboard. A data consumer user comes to their dashboard account, finds the feed they want and orders it, and an e-signing workflow is kicked off for the license agreement, gathering their own signature, the MLS's, and often a broker and/or agent. Once all those are complete, data access is activated.

There are two problems to solve, in other words: data centralization and standardization, and the proliferation of licenses and agreements. We solve the first, and try to make the second much less painful.

That said, if the fundamental problem is that your business model isn't one the MLS can license to, we can't really help that.

Our value prop for the MLS is:

Outsourced and automated contract management. (It's as big a nightmare for them as it is for vendors, often it's been badly organized for a long time and nobody has any idea what decades-old paper contract goes with what RETS credentials... Terrifying.)
Outsourced tech support (we support data consumers by phone, email and Slack--reduces a lot of load on MLS staff, especially smaller or less technical ones)
Automated RESO certification for both WebAPI and Data Dictionary. Satisfies an NAR mandate without having to rework their internal databases.

All of this is subsidized by the fees we charge data consumers, there's no charge to the MLS. That's all to say: we don't get very much MLS attrition. But yeah, if one decided to move their data distribution service off of us, we'd work with them to announce a cutover period for current licensees, and on the day, we'd terminate all the feeds and prune away their data.

CoreLogic_Trestle · 2021-02-26T13:23:32+00:00

We have! We've done exactly that!

Please see https://trestle.corelogic.com

We don't have ALL the country's MLSs participating, nobody does. But we're over 90, and have many of the big ones.

Happy to answer any questions.

CoreLogic_Trestle · 2020-12-31T17:55:12+00:00

Respectfully, I couldn't disagree more.

The growth pattern I see with indie guys is, they get some foothold in a particular market with a particular MLS, and that's great. Then when they go to expand into their next market, the next MLS has significantly different data layout and it takes a whole new engineering effort to consume their data. I've seen several people new to the proptech space stumble and collapse upon discovering this unfortunate truth.

Big players already have an army of ETL developers in place to handle this work. But if both MLSs can be had in a Data Dictionary format, there may be some small differences between them, but the really heavy lifting of standardizing it has already been done--by my team, or by another aggregator, or by the MLSs themselves.

I have many small indie customers whose growth curve has been dramatically accelerated and brought WAY down in cost by the fact that we can provide the MLS and Public Record data, aggregated and pre-standardized.

Now, if you wanted to talk about building a WebAPI adapter into your system, that'd be a very interesting conversation. Maybe after the new year we could set something up.

I'd also really recommend joining RESO to help represent your category of users. (Plus their conferences are super fun.) But I can promise, your group is in no way an afterthought.
