It's my first year in programming and there was nothing new actually. I don't even think that pain was worth it I'd just make the scraper in js and make it return a json string.

Nice video. It’s worth noting as well that many APIs will pageinate, so rather than checking how many total results exist and manually iterating over them - you just check to see if the ‘next page url’ or equivalent key exists in the results and if so, get that too until it doesn’t exist anymore, merging/appending each time until the dataset is complete 👍

In fact you can see at 05:33 that this particular API does just that - there's "nextPageURL" and "totalPages" at the end of the response JSON.

I rarely praise anything, but this tutorial was SO good! Well explained, no filler. In 7 or 8 minutes you guided me through finding the hidden information I needed, which tools I need to use and how to automate it. This tutorial gave me enough confidence to try to write my first Python script! Within hours I built a scraper that can pull all metadata for a full NFT collection from a marketplace. Without this video it would have taken days/weeks to discover all of this

Please ignore my first comment. I checked out your first video in this series and learned about using scrapy shell to test each line of code. With that I found the bug in my code. The code worked PERFECTLY as advertised. Your the man! Much thanks!

This is, no joke, the most useful video I ever saw on KZread!

My man, this is EXCACTLY what I was looking for. Had to do some extra steps, but a little try-and-error and basic understanding of HTTP was enough to solve my problem. Thank You!

This video came into my feed just a couple days after I used exactly this method to collect some data from a website. Very good info! This is much easier than web scraping. Unfortunately, in my case, the data I could get out of the API was incomplete, and each item in the response contained a URL to a page with the rest of the info I needed, so I had to write some code to fetch each of those pages and scrape the info I needed. But much easier than having to scrape the initial list, as well.

Thanks for this - and other - videos, John. Super helpful! Regarding the cookie expiring, can you suggest a way to use playwright to programmatically generate the cookie used on the API request? I am assuming that cookie isn’t the same as the cookie used for the request of the html but maybe that’s wrong?

Nice tutorial on scrapping, some tricks I have been using myself, and some others never heard of until now thx for sharing!!! Small adjustments if I may (please don't take this as criticism) I think you don't need to loop over each product to copy it to your res, you can use extend instead, also I think the header didn't change so you can take it out the loop over pages

Thank you, your videos has automated my job. All i need now is a AI cam of myself

Greetings from Brazil! Thank you! I just had to adjust some of the quote marks on the header (there were some 'chained' double quotes (like ""windows"")), making some of the header's strings be interpreted by python as code, not text. Just had to change inner double quotes for single quotes (e.g. "'windows'") and it worked perfectly!). Can't wait to try your other tutorials! Once more, thank your very much!

Thanks for the video. Not new to python, pandas, or API's, but do need to start scraping pages for the API as some are not published, or not documented well. Thanks.

Instead of looping over the list and doing an append of each individual item, you can do list().extend(list()) which extends the list with the new list. The result of this is 1 list of dictionaries (basically an identical result to how you did it) but with less and cleaner code.

This is seriously high level content right here

John, a specific video about how to scrape React website would be nice. It uses a mix of html and JSON data on pages...just an idea. Keep up the good work loving it.

Hello John! I have a quick question then - this will give you much more information then you might need if you don't change anything in Insomnia, will deleting the headers remove some of this? Or is it more likely to change based on what you put in the "for p in data " section? i.e. if I include keys that are further indented, will I just receive those keys as oppose to everything nested in an undented key? I found this extremely useful though and have been using it since!

Love your content

Great content! I just have one question: Which web browser you are using in the video? The response tab on my browser is not structuring the received data. It just shows it in a single line.

If you call hidden APIs from a page where for example there are four categories run by Javascript with hidden APIs and three of them need clicking on by a webdriver to be fetched, should you just simultaneously request the hidden APIs in the code or should you write an automation scraper to click on it each time? I tried the code with only directly requesting the hidden APIs for all categories with time.sleep(2) in between and it worked but just wondering if it would risk being detected and blocked as an autoscraper? thanks.

As always - great content - well presented. I tried out your code today and unfortunately scrapy, although it outputs a data dump of the source page, it's unable to download the json data. I tried a bunch of settings changes to no avail. Any quick suggestions to where to look for a fix? Thanks in advance for you time.

You are the best sir!
