Man, the zillow rent api is such a headache. I ended up using a third-party tool like Scrapy to scrape rental data instead. Not ideal, but it got the job done when the API kept failing.
If you’re set on using Zillow, try their developer forums. There are some threads with workarounds for common issues.
