I have JSON data from a URL, I wanna pass it into a search box suggestion/autocomplete, I'm using flask framework.

so how I can make a post request with the payload of every letter click and handle it from the backend with flask and return the values as a search bar suggestions

JSON example:

{
    "spider":[  // if the user typed spider 
       {
          "t":"Spider-Man: No Way Home (2021)",
       },
       {
          "t":"Spider-Man: Far from Home (2019)",
       },
       {
          "t":"Spider-Man: Homecoming (2017)",
       },
       {
          "t":"Spider-Man: Into the Spider-Verse (2018)",
       },
       {
          "t":"Spider-Man (2002)",
       },
       {
          "t":"The Spiderwick Chronicles (2008)",

       }
    ]
 }

The JSON data is changeable depending on what the user typed , I cant store all the values locally it's a live API.

please help.
