Script development to fetch walmart data and sending discord

Here are details.
-Application flow:
suppose we have to find knife(specific) on walmart.
We will first query the item name (that specific knife) on walmart portal then it will show us a list pincodes with that product.

In the above list item may or may not be available(out of stock) so we will try to to find all the stores in which that item is available.
then we will pick the cheapest from all those available pincode.
and it will be sent to discord

-Total flow
1. one request will be sent with the keyword
for e.g. “knife set”
wallmart gives maximum of 25 pages for query keyword.
2. we will fetch first item from the result.
3. we will send another request with productId and in response we will get all postal code it is availble on.
then we will iterate through each postal code.
this iteration will send a request in each iteration and will fetch the price for that postal code.
4. we will save the result in a list
5. we will compare and find out the lowest price item with store id and then we will prepare the product url.

it may take a few second if it is available on all the stores.

The whole process will be repeated for each search result.
I need only experienced one, start your bid with walmart if you read.
Thanks
