# Zillow Building & Apartment Data

<p>Get a building or apartment record: name, full address, building type, unit count and rent ranges, floor plans with per-unit pricing, amenities, resident reviews, photos, and map imagery links.</p><h2>Addressing a building</h2><p>Pass a building URL path, a lot id, or a latitude and longitude pair. When you pass a URL path, its trailing building token is decoded automatically, and the returned address is checked against the city and state in that path — a mismatched address is reported as an error rather than returned as a valid building.</p><h2>Not every building resolves</h2><p>Roughly 5% of valid identifiers have no building record. Those return <code>found: false</code> with a null building, which is a normal outcome and is never retried.</p>

## Errors

| Status | Error | Description |
| --- | --- | --- |
| 400 | The request validation failed | A query parameter is missing, malformed, or outside its documented range. This is the only Zillow response that carries no error code: the body has a message and a field list and nothing else, so match it on the 400 status. |
| 422 | No research dataset matches that family and geography | The requested research file does not exist for the combination given. |
| 422 | More than one research dataset matches | The family, geography and variant given do not identify a single research file. |
| 422 | No accuracy figures are published for that region | The named state or metropolitan area publishes no estimate-accuracy data. |
| 422 | The upstream rejected the request | Zillow answered with a deterministic 4xx. |
| 422 | The building returned does not match the requested address | The decoded building token resolved to a building at a different address than the slug names. |
| 503 | The listing source answered with a block or rate-limit page | The request reached the source, but what came back was a challenge or rate-limit page rather than the data. |
| 503 | The listing source returned a server error | The request was served and answered with a 5xx. |
| 503 | The listing source did not answer in time | The request was sent and no answer came back before the deadline. |
| 503 | The request could not be sent | No approved exit could be reached, so the request never reached the listing source. |
| 503 | No approved exit is available | There was no usable approved exit to send the request through. |
| 503 | The upstream returned a document this integration cannot read | The publisher changed the shape of a response or served a document that is not the expected file. |
