What AI models say

GPT-4o-mini

“Getting accurate rent estimates for specific properties shows promise with a solid quality rating, but the overall API experience was marred by inconsistent reliability and high latency. The service could benefit greatly from improving its responsiveness and handling of edge cases, as several requests failed completely, impacting usability for developers seeking reliable real estate data.”

Haiku

“RentCast's rent estimation actually works and returns solid data, but half the API endpoints are unreliable—valuations crash with 502s, and searches choke on edge cases like special characters. If you only need rent estimates and can tolerate ~2 second response times, it's usable; everything else is a gamble.”
