There is no public, self-serve StreetEasy listings API established by the official sources reviewed as of September 29, 2026. StreetEasy’s published advertiser terms prohibit automated scraping or data extraction from the Zillow Network unless Zillow expressly permits it in writing. For authorized NYC listing data, ask REBNY about its Residential Listing Service (RLS) feeds and licensing process. A scraper that happens to work is not proof of permission, a data license, or a stable source.
Can you scrape StreetEasy listings with an API?
Not on the basis of a publicly documented, unrestricted API. The official materials reviewed do not establish a public StreetEasy API that any developer can sign up for to collect listings. StreetEasy’s advertiser terms, updated February 13, 2026, say automated scraping or data extraction from the Zillow Network is prohibited except as expressly permitted by Zillow in writing. The same prohibited-uses list bars attempts to disable or circumvent technological measures used to control or limit access.
That is a published platform restriction, not a complete legal analysis of every possible user, agreement, or use case. If your project needs StreetEasy data specifically, ask Zillow for written authorization covering the collection method and intended use before building it. Do not treat a browser-accessible page, an API key found online, a third-party wrapper, or a successful test request as permission.

What authorized NYC listing-data routes should you investigate?
Ask REBNY about RLS feeds and licensing
REBNY describes its Residential Listing Service as a managed service for sharing exclusive listings among participating firms across Manhattan, Brooklyn, the Bronx, Queens, and Staten Island. Its technical-solutions information describes IDX, VOW, Product, and other feed options, along with a direct data-license application and review process for prospective syndication partners and pre-licensed data providers. These are routes to investigate, not a guarantee that a particular applicant or product will qualify.
Before designing around an RLS feed, ask REBNY about current eligibility, fees, available fields, permitted display and downstream use, attribution, refresh limits, retention, and provider requirements. REBNY’s FAQ says active membership alone does not automatically provide RLS access. It describes approved listing-management providers for members and says non-member firms may participate under a separate agreement and fee structure if they meet applicable conditions. Confirm the current requirements directly with REBNY.
Understand what the RESO Web API does—and does not do
REBNY announced on January 21, 2024, that its RLS had completed migration to the RESO Web API. That tells you about the technical interface used by the service; it does not make RLS data public or unrestricted. RESO is a standards body, not a source of MLS listings. A data recipient must agree to the local MLS’s data-use and licensing rules and obtain credentials and instructions from the MLS provider or its technical staff.

In practical terms, “we support RESO” answers a compatibility question, not an authorization question. You still need a licensed data source, credentials with the right scope, and an approved use for the fields and listings you receive.
Use NYC Open Data for municipal records, not as a StreetEasy feed
NYC Open Data provides API guidance for city datasets. A relevant municipal dataset may complement a property application—for example, where your product also needs a government record—but check the individual dataset’s fields, geographic coverage, update cadence, and terms. NYC Open Data is not established as a source of StreetEasy’s live listing availability, listing descriptions, photos, or agent information.
Compare the routes before building
| Route | What it provides | What to confirm first | Main trade-off |
|---|---|---|---|
| Written StreetEasy/Zillow authorization | Permission for the collection method or use Zillow expressly allows. | Scope, permitted methods, fields, rate limits, storage, redistribution, term, and fees. | Most direct if granted; availability of such permission is not established by the reviewed materials. |
| REBNY RLS feed or license | Listing data through REBNY’s managed feed and licensing routes. | Eligibility, feed type, use and display rules, fields, fees, provider, attribution, refresh, and retention. | An authorized listing-data route, but access is governed and may not fit every project. |
| RESO Web API through an MLS or data provider | A standardized technical interface to listing data made available by a provider. | Local license, provider, credential scope, schema, and update behavior. | Standardizes transport; it does not supply data or rights on its own. |
| NYC Open Data API | Government datasets published by the city. | The specific dataset’s fields, geography, cadence, and license. | Useful for municipal information; not a StreetEasy live-listings replacement. |
| Third-party scraper or hosted wrapper | A vendor’s claimed convenience layer for collecting or returning listing information. | Written rights, provenance, allowed downstream use, continuity, accuracy, and security. | Convenience can come with unverified authorization and dependency risks. |
Keep listing-submission rules separate from data access
StreetEasy’s Listings Quality Policy describes a same-calendar-day direct-entry submission requirement for publicly marketed exclusive sale listings. Separately, a StreetEasy Team article dated September 24, 2025 describes a one-business-day publication standard for covered publicly marketed listings. These descriptions concern agents’ listing submissions and marketplace policies, not permission for a third party to collect listings.
The September 2025 article says the standards apply to exclusive for-sale listings, not rental listings, for-sale-by-owner listings, or certain sponsored developer units. StreetEasy also says true office exclusives may be allowed under specified conditions, including seller disclosure and no public marketing. The scope differs by policy and listing type; verify the current policy if your business depends on a particular case. Neither the submission timing standards nor access to a listing on the marketplace should be read as an API grant.

Get the data-rights questions answered before you choose an API client, database, or refresh schedule. Record the answers in the agreement or written approval, rather than relying only on a salesperson’s description.
- Provenance and rights: Who is the source of each field, and does the provider have written rights to supply it for your use?
- Purpose and audience: May you display, analyze, or otherwise use the data in your intended product and geography?
- Content-specific rights: Are photos, descriptions, agent details, and other content covered, or are separate restrictions applicable?
- Attribution and display: What notices, logos, display rules, or consumer-facing disclosures are required?
- Operations: What are the rate limits, refresh expectations, update semantics, and permitted retention period?
- Security and termination: How must credentials be protected, and what happens to stored data if access ends?
- Downstream use: Can your affiliates, customers, or subcontractors access the data, or is use limited to your own application?
Apply the same checks to an aggregator or hosted scraper. A convenient endpoint does not itself establish the vendor’s provenance, contractual rights, permission for your downstream use, or continued availability. Avoid choosing a vendor solely because its demo returns records.
How to implement an API after you have permission
The data provider’s documentation and agreement must define the actual endpoint, authentication method, fields, pagination format, and update rules. Those details are not established for a public StreetEasy API, so there is no responsible way to give a StreetEasy URL, credential name, or ready-to-run request as if one were documented. Once REBNY or another licensed provider supplies its approved API documentation and credentials, use that specification rather than guessing an endpoint.
Build a small, auditable ingestion path
- Request the narrowest useful access. Ask for only the fields, geography, and feed type your approved purpose requires. Keep a copy of the written license and provider’s current technical documentation with your project records.
- Authenticate as documented. Store secrets in a secret manager or environment configuration; do not commit them to source control, browser code, logs, or support screenshots. Follow the provider’s token rotation and IP or application restrictions if specified.
- Handle pagination explicitly. Follow the provider’s documented cursor, page token, or continuation link until the response says there are no more records. Do not assume a page size or invent a pagination parameter.
- Make updates incremental where supported. Use the provider’s documented modification timestamp, change feed, or sync token. Persist the last successful checkpoint and advance it only after records have been validated and stored.
- Make retries safe. Retry transient network failures and documented rate-limit responses with bounded exponential backoff and jitter. Respect any retry-after instruction. Do not retry authorization failures indefinitely.
- Validate and minimize. Check required identifiers and expected field types, reject malformed responses into a reviewable error path, and retain only data allowed by the license.
- Log operations without leaking data. Record request IDs, time, status, duration, page/checkpoint, and error class. Redact credentials and avoid logging full personal or listing payloads unless expressly permitted and necessary.
- Plan for change and shutdown. Monitor schema and provider notices, version your parser, and maintain a deletion/export process for when a license changes or expires.
A useful implementation separates the provider adapter from your application model. Map provider fields into an internal schema only after documenting field meanings and update behavior; keep the source identifier so corrections and removals can be reconciled. This reduces the chance that a provider-specific schema change silently alters what your product displays.
Performance, reliability, and cost considerations
Do not estimate operating cost from an assumed public StreetEasy quota: no such quota is established here. For a licensed feed, obtain the actual recurring fees, request limits, refresh obligations, and data-retention conditions from the provider. Batch or incremental updates only when the interface and license permit them; aggressive polling can waste requests and may breach provider limits.
Reliability depends on the licensed source’s documented service expectations and your handling of partial failures. Track the age of your last successful update, distinguish an empty result from an API error, and alert when a checkpoint stops advancing. Preserve an idempotent upsert strategy so replaying a page after a timeout does not create duplicate listings. Treat removals and status changes according to the feed’s documented semantics rather than assuming a missing record means it was deleted.
For a user-facing product, disclose meaningful freshness limits and avoid presenting stale records as current availability. Keep a clear recovery path: pause publication if the feed is no longer authorized, preserve operational logs needed for diagnosis, and follow the license’s instructions for stored data.
Common problems and how to respond
- A supposed StreetEasy API key or endpoint fails: It may be undocumented, private, expired, or unrelated to an authorized public service. Do not probe alternate endpoints or circumvent access controls. Ask Zillow for written permission or pursue a licensed RLS route.
- A scraper returns a CAPTCHA or bot check: Stop rather than trying to evade the control. StreetEasy’s published prohibited-uses list bars attempts to disable or circumvent technological measures, and technical success would not establish a license.
- A vendor says its data is “from StreetEasy”: Request the provenance, written rights, allowed use, field and photo rights, and downstream terms. If the vendor cannot substantiate them, do not build a product dependent on the feed.
- REBNY membership does not unlock a feed: Membership alone does not automatically provide RLS access. Ask REBNY which provider, agreement, application, and eligibility conditions apply to your organization.
- A RESO-compatible client has no data: RESO defines a standard, not a listing database or entitlement. Obtain the local provider’s approved credentials, documentation, and data-use agreement.
- Records appear stale or disappear: Check the provider’s documented update cadence, sync token/checkpoint, status semantics, and error logs. Do not silently substitute scraped data when an authorized feed is delayed.
- A city API lacks photos or live availability: Confirm that the specific municipal dataset actually contains the fields and update cadence your application needs. It is not established as a StreetEasy listing feed.
