Detect listings with any changes using the modification timestamp filters
Use Case: Get All Updated Listings Every Day
Current Date: April 2, 2025
Goal: Pull all of the updated listings from yesterday - April 1, 2025
Assumptions: You have already completed a large initial load job and have the listing_id's for everything you have pulled/care about. You will compare the records/listing_id's you pull in this code to what you already have cached and update the relevant records on your side.
let input = {
size: 250,
modification_timestamp_min: "2025-04-01",
modification_timestamp_max: "2025-04-02"
}
//-OR-//
//use "city", "mls_board_code", "zip", or other geo filters to prioritize your updates
let input = {
city: "Richmond",
state: "VA",
modification_timestamp_min: "2025-04-01",
modification_timestamp_max: "2025-04-02"
}
//process results and get all the listing_id's in an array
//compare to each listing ID you already have cached to see which ones need updating
//you may need to perform paging to get all results
//Get count of how many need to be updated
{
count: true,
modification_timestamp_min: "2025-04-01",
modification_timestamp_max: "2025-04-02"
}
// 190,691 RESULTS
// requires 190,691 / 250 (max size) = 763 MLS Search API calls
// ~100ms per request = 76.3 second job time = 1.27 mins
//Pagination Flow of Queries
