Trestle
Trestle provides real estate data delivered via WebAPI and RETS. We aim to help you write your first WebAPI client, configure a RETS library to work with Trestle, or scale your solution to meet the demands of aggregating multiple MLSs. If there are questions left unanswered, you may reach out to us via email. You can also request to join our support slack if you are not already on there.
*Please be advised that CoreLogic is switching the Trestle™ API URL to a new URL

We
are happy to announce the release of Data Dictionary 2.0. With this release
Trestle systems will be RESO 2.0 certified, which means that you will have a
dramatic improvement in standardization coverage. Trestle offers a single
schema, delivering consistency to our users across every MLS. As such, you will
see as this change rolled out to all customers at the same time. There are a
few new features that you can take advantage of with this update, but in
general, your biggest concern should be making sure that your fully replicated
datasets are up to date.
When: Monday, Sept
30th 6AM EST - 12PM EST
What
to expect
- On
Release, you will see the new enumeration values in the metadata.
- A data
refresh will occur in reverse order, correcting newer records first.
- We
will only touch ModificationTimestamp
for On-Market Listings.
- All rows
going forward include the new values.
- The entire
dataset will be updated over the next two weeks.
Reference
“What to Do” below for details.
What to Do
Review Changes:
- If you
consume these fields as is, you may not need to make a change.
- If you are
using enumeration values in your code or have complex mapping, you will
need to review.
- Most users
do not search on these fields.
Be prepared to update a lot of rows:
- We expect
over 200m row updates across all resources.
- Most of
our users are conditioned to the fast pace of our updates and will have no
issues consuming data at the rate that we provide it.
- If you
need additional quota, please reach out or upgrade to our Premium Quotas
for a permanent boost.
- We will
only touch ModificationTimestamp for On-Market Listings.
- You should
repull off market data in a few weeks. We will send a reminder when all
accounts have been refreshed.
Metadata changes:
- Check for
changes in namespace.
- Check for
changes in your internal references (are you mapping an enum to another enum?).
- Consider
moving to Lookup/Field resource.
Major Changes
CoreLogic's CLIP is now available:
- CLIP
(CoreLogic Integrated Property) is a Machine Learning driven record
identifier based on CoreLogic assets. Use it to uniquely identify a
property across vast datasets.
- Interested
in additional datasets that you can use with CLIP? Ask us about our
collection.
UPI is now available:
- UPI is a
Universal Parcel Identifier for each listing based on the concatenation
for other values. Lean more about UPI at
City / County lookups:
- Data type
is being changed from a String to a Lookup
- You will
see case changes but should not see any value changes at this time.
- You can
find references to the available Lookup values in the lookup resource.
- Over time,
we will continue to standardize these values.
CustomFields json blob:
- This field
is being converted into a stringified JSON.
- If you
rely on this field (the blob), please let us know as we are considering
deprecation in favor of a more standard approach.
Data Type Changes:
- Some
strings were made enumerations and vice versa.
- See our
field change documentation.
New Field & Lookup Resources:
- You can use
these resources for determining available lookup values.
- You can
filter this for a specific MLS.
Metadata is much larger:
- RESO
certification requires that Enumerated fields must have all values in the
metadata.
- If large
Metadata files are a concern, use the Lookup Resource.
New field type of Lookup:
- Fields
like PostalCity, CountyOrParish
will be exposed as a string, with a reference to the Lookup Resource.
- You can
use the Lookup resource to find available values for Lookup fields and
enumerations.
Massive enumeration value changes
- RESO 2.0
testing enforces parity between a payload and the enumeration/lookup.
- The most
common fields:
- ListAOR
- ListAgentAOR
- ListOfficeAOR
- BuyerAgentAOR
- BuyerOfficeAOR
- BuyerFinancing
- Possession
- LeaseTerm
- MediaType
- See our
field change documentation.
