the response.json() I'm getting from KIWI is either exactly what I'm expecting or it's
"{'status': 'Bad Request', 'error': 'unknown partner provided - if you would like to cooperate with Kiwi.com, please register at tequila.kiwi.com'}".
I'm having it repeat the request for each city with a for loop so nothing changes per iteration but the destination city (I've tried to only supply required parameters), yet it randomly works and randomly doesn't with the exact same code, run multiple times, it seems entirely random if it works or not. Any clue why? It has given a proper response with an empty list for "data" as well, it just randomly (although its most of the time) responds with said error.

Since Sheety allows 200 requests per month for free accounts delete a few entries in the Google sheet to save the requests. Currently, there are 11 entries so every time we run the code it takes 11 requests.

The API is not working on my own side
