# Zillow Open Houses

<p>List the homes for sale that have an open house in a US city or ZIP code. Each row has the address, price, bedrooms, bathrooms, living area, Zestimate, type and the open house windows as ISO 8601 UTC start and end times.</p><h2>Paging</h2><p>A page holds up to 41 rows. <code>max_page</code> is the number of pages the site reports for the area (at most 20). A page above it answers 422 and costs nothing. <code>total_results</code> is the number of open houses Zillow reports for the area. Every returned row has at least one open house, and <code>open_house_text</code> is the site text, such as "Open: Sun 12-2pm (11/1)".</p><h2>Right place only</h2><p>Every row lies in the place you asked for. A page for another city, state or ZIP code is never returned. <code>days_on_zillow</code> is null here: the site does not publish it for open houses.</p><p>Costs 1 credit per request.</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. |
