The current scraper already does the job. It runs well.. until hit ""HTTP Error 403: Forbidden"" error. Not sure about exact reason why this is happening. But I read that its request must be less than 10 requests per second, and also avoid time between 9pm and 6am Eastern Time. Try to reduce the request frequency to very low frequency, and add a line to pause during the forbidden time. Then run it. Check if it runs to the end. When you bid, write how you will do this project in detail. If you don't, your bid will be immediately removed.

Hi, From what I can see, using time module would be good enough to introduce a time gap between each request. Also, we can do something about the Forbidden Time with Datetime module. We'll have to specify some more things but this should be the gist of it. Please contact me if you're interested in working with me.

Hello! I can use Python lib 'datetime' to determine the time frames when we cannot scrape and the number of requests per second may be limited in different ways, depending on how multithreading is made in your code. I suppose this is a 1-day job.

Hi, To lower the frequencies I can introduce explicit delays to wait between requests, and checks time to pause during the time you specified, first of all I would need to see the code so that I can comment further,contact me to hire.

Hi there, I have plenty of experience writing and debugging web scrapers. For the rate limiting, I can just include a simple constant sleep (i.e. 1/10th of a second), unless a more complex solution is required by the specifications. And for the forbidden time, I can simply check if the current time is within the bounds of the forbidden time, then wait and try again. I'm looking forward to discussing this project further with you. Thanks, Brandon

Hey, I'm a 3rd year computer science undergrad student and I have a solution to your problem. I have had the same problem while making one of my projects. For the restricted time constraint part, we can compare system time periodcally to make requests. For the Http error part, we can start with a try catch block and work up the ladder.

Hey! I will add a restriction function before http requests sent. 1. It will count how many requests to a given address have been made in the past second and when X more than 10 will wait 1 second before next request. 2. It will find current time and restrict http requests from 9pm to 6am Eastern Time I'm new here so I am really enthusiastic about my first job. Your job is a good match for me because I was using same restrictions function when building a Telegram bot with limits on how many requests per second are allowed.

by adding a small sleep after each scraping call, we can ensure that rate limiting of 10 requests per second is not violated. Regarding the Peak hours, its best to change the scheduler (cron etc) to run only between a set interval thus ensuring less CPU consumption and less hosting bill :)
