How to use the zillow api with ZillowR - r

Question

I want to access the GetDeepSearchResults info from the Zillow API.
My code:
library(ZillowR)
zapi_key = getOption('Myapikey')
GetDeepSearchResults(
address = '600 S. Quail Ct.',
zipcode = '67114',
rentzestimate = FALSE,
api_key = zapi_key
)
Error:
Error in GetDeepSearchResults(address = "600 S. Quail Ct.", zipcode = "67114", :
unused arguments (zipcode = "67114", api_key = zapi_key)
Why does this error occur? What can I do to fix this?
Edit: I changed the code according to the comments and got this:
My code:
library(ZillowR)
zapi_key = getOption('myapikey')
GetDeepSearchResults(
address = '600 S. Quail Ct.',
citystatezip = '67114',
rentzestimate = FALSE,
zws_id = 'myapikey',
url = "http://www.zillow.com/webservice/GetDeepSearchResults.htm"
)
Output:
$request
$request$address
NULL
$request$citystatezip
NULL
$message
$message$text
[1] "Error: invalid or missing ZWSID parameter"
$message$code
[1] "2"
$response
NULL
How can I fix this?

Answer 1

The unused arguments error is typical when you pass arguments, which are not parts of the function. So R doesn't know what to do with those and returns the error. You can check the documentation of the function with ?GetDeepSearchResults
This shows you the usage:
GetDeepSearchResults(address = NULL, citystatezip = NULL,
rentzestimate = FALSE, zws_id = getOption("ZillowR-zws_id"),
url = "http://www.zillow.com/webservice/GetDeepSearchResults.htm")
To have this work, you have to set your id first with (you can create an id on https://www.zillow.com/howto/api/APIOverview.htm):
set_zillow_web_service_id("youractualkey")
So you function does not have the argument zipcode and api_key. Let's change your arguments to some which exist:
GetDeepSearchResults(address='600 S. Quail Ct.', citystatezip ='67114',
rentzestimate=FALSE)
You surely recognized I did not use your api_key. This is because the default:zws_id = getOption("ZillowR-zws_id") calls your global 'ZillowR-zws_id' which you just set with the set_zillow_web_service_id() command. So it's not necessary to change the default value. But you can skip this when you use zws_id ="youractualkey" from zillow
I made a random account I set up for validating. This gives me the output:
$request
$request$address
NULL
$request$citystatezip
NULL
$message
$message$text
[1] "Error: this account is not authorized to execute this API call"
$message$code
[1] "6"
$response
NULL
So I could successfully contact the server and my key was recognized. The account authority is not R related and has to be set on the website.
