SimplyRETS
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 section. ### Authentication 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 m
Plan the first integration safely
The access fields below come from the connected directory. Their likely implementation impact is explained without assuming provider-specific behavior.
Authentication
OAuth is reported. Confirm flows, scopes, consent, token lifetime, and refresh rules.
Transport
HTTPS is not confirmed. Do not send credentials or production data until secure transport is verified.
Browser access
CORS is unknown. Treat direct browser access as unconfirmed and test before choosing a client-only architecture.
First-request sequence
- Identify the current base URL, version, and endpoint for the use case.
- Confirm how credentials are issued and where they may be stored.
- Test success, invalid input, throttling, unavailable data, and timeouts.
- Record response fields, pagination, caching, and error shapes.
- Add monitoring, retries with backoff, and an appropriate fallback.
Questions to resolve before production
Pricing and quotas
Confirm current plans, free-tier limits, overages, and request ceilings.
Endpoint coverage
Check that the operations and response fields match the intended workload.
Reliability
Look for uptime history, a status page, support routes, and service commitments.
Data and privacy
Review retention, licensing, regional processing, and compliance requirements.
Versioning
Confirm the active version, change policy, deprecation window, and migration guidance.
Developer experience
Validate SDKs, examples, error formats, pagination, and test environments.
