Version: 1.0.0

Use this API in your project

Start working with "SimplyRETS API" right away by using this ready-to-use mock sample. API mocking can greatly speed up your application development by removing all the tedious tasks or issues: API key provisioning, account creation, unplanned downtime, etc.
It also helps reduce your dependency on third-party APIs and improves your integration tests' quality and reliability by accounting for random failures, slow response time, etc.


The SimplyRETS API is an exciting step towards making it easier for
developers and real estate agents to build something awesome with
real estate data!
The documentation below makes live requests to our API using the
trial data. To get set up with the API using live MLS data, you
must have RETS credentials from your MLS, which you can then use to
create an app with SimplyRETS. For more information on that
process, please see our FAQ, [Getting
Started]( page, or
contact us.
Below you'll find the API endpoints, query parameters, response bodies,
and other information about using the SimplyRETS API. You can run
queries by clicking the 'Try it Out' button at the bottom of each
The SimplyRETS API uses Basic Authentication. When you create an
app, you'll get a set of API credentials to access your
listings. If you're trying out the test data, you can use
simplyrets:simplyrets for connecting to the API.
Media Types
The SimplyRETS API uses the Accept header to allow clients to
control media types (content versions). We maintain backwards
compatibility with API clients by allowing them to specify a
content version. We highly recommend setting and explicity media
type when your application reaches production. Both the structure
and content of our API response bodies is subject to change so we
can add new features while respecting the stability of applications
which have already been developed.
To always use the latest SimplyRETS content version, simply use
application/json in your application Accept header.
If you want to pin your clients media type to a specific version,
you can use the vendor-specific SimplyRETS media type, e.g.
To view all valid content-types for making an OPTIONS, make a
request to the SimplyRETS api root
curl -XOPTIONS -u simplyrets:simplyrets
The default media types used in our API responses may change in the
future. If you're building an application and care about the
stability of the API, be sure to request a specific media type in the
Accept header as shown in the examples below.
The wordpress plugin automatically sets the Accept header for the
compatible SimplyRETS media types.
To paginate through listings, start your query with these
parameters: 'limit=500&lastId=0'. The 'lastId' is the important
part, you can use any limit up to 500. When you receive the
response from the API with the results, check the 'Link' header for
the 'next' link. That link is pre-built to access the next 'page'
of listings. Alternatively, you can use the last listing's 'mlsId'
from the previous request and use that in the next query. For
First query:
curl -u username:password ''
If the 'mlsId' in the last listing of the results is '1234567', then the next query will be:
curl -u username:password ''
...and so one until you have reached the final page of listings.
There a few pieces of useful information about each request stored
in the HTTP Headers:
X-Total-Count shows you the total amount of listings that match
your current query.
Link contains pre-built pagination links for accessing the next
'page' of listings that match your query.
RETS Vendor Compliance
Many RETS vendors have strict requirements for showing disclaimers
with specific information embedded. For example, in many areas it's
required to show the timestamp of the time the listings were
refreshed inside a disclaimer or on a listing page.
The timestamp of the last listing refresh timestamp can be found in
one of two spots:
The X-SimplyRETS-LastUpdate header from GET /properties or GET /properties/{mlsId}
Calling the API root / or properties api endpoint /properties
with an OPTIONS request
This request will show the last update timestamp for all RETS
vendors associated with your application. Look for the
updates list in the JSON response.
OPTIONS /properties
Using this request, look for the lastUpdate field in the JSON
