This technique kind of only works for Client-Side Rendered sites. Not SSR sites (server side)

[@abg44]

This analysis is on the client side. Allows you to continue checking the APIs for any exploits. That allows you to find the connection medium that exchanges client data to the server

It would struggle with HTMX too, heh.

[@pr0skis]

this technique is really for CSR sites. with more and more sites switching to SSR it's not really possible to just go straight to the APIs

[@wkoell]

In most cases SSR is just for the first page, so robots get their mouth filled with right stuff. Next pages are hydrated on the client side over the API. This is the evolved pattern.

[@pedrolivaresanchez]

I’m new to data scraping, so please excuse my lack of knowledge, but I wanted to ask: since SSR delivers fully rendered content directly to the client, wouldn’t it be simpler to scrape data from SSR websites compared to CSR?

That's exactly what I was going to say.

[@hurtado-w9c]

​@@pedrolivaresanchez No, CSR pages typically include endpoints that return clean, structured data in formats like JSON (as demonstrated in the video). In contrast to SSR, where you need to parse through HTML to extract the desired data (which also includes a bunch of unwanted CSS and JavaScript).

Nice I ran into the same curl 403 issue while writing a GoLang scraper and used cf-forbidden to complete my request.

[@wontdisappoint]

I also scrape data as a living, particularly job data. This is all great information. Another really good point is sometimes you have to loop over tags In the front end to extract an ID for each item. Building robust solutions that can withstand changes is a learned skill.

[@ronburgundy1033]

How can I learn this and do it as a living? Can you make 20k a year ?

[@wontdisappoint]

@ronburgundy1033 If you're working for yourself, it could be difficult and take some time, You can build up a bunch of data that you have scraped and try to sell the data. You can sell your services to a company who wants something scraped. You can work for a company that does their own scraping. Honestly, there's a lot of ways to go about it but think of it as providing a service and providing data and you can come up with some good Solutions. In regards to learning, find some sites that you want to try and scrape and start there when you have a problem ask on stack overflow or something. There is also no code options like uipath

[@stephena8965]

Amazing tutorial as always! Can't wait to try this in production! For any potatoes like me on older python versions here are some changes you have to make: 1. import 'from typing import Optional, List' 2. update 'rating: float | None' to "rating: Optional[float] = None'

[@KaiPetro]

It is a bit of reverse engineering. At least in perspective of not having docs and exploring related endpoints to obtain the required data. He even touches on the request params of start, etc to explore options not used on the site. Ive done something similar to explore a bunch of search indexes that had led me to more data than was initially available on the websites.

[@dalaciu]

100% percent agree that front end scraping sucks. I remember having a hard time with python selenium because of different class names being generated with inconsistent names (maybe just to discourage scraping). For my last scraping project I used Deno Typescript. The API was only returning the HTML page for the web app and I had to install a proxy certificate on my phone and read those mobile requests that a actually returned JSON objects. You have to get creative from time to time, but there is no such thing as an unscrapable APIs😅. Thanks for sharing your workflow!

Could you clarify when and why these restrictions happen and how you managed to bypass them?

[@harri00413]

When something is published it can still have copyright and does not allow other use than the owner’s use. Could be illegal.

[@KaiPetro]

If the owner also intended that you watch ads or make purchases along with viewing the data/content, that is not covered by copyright laws. It is similar to using ad blockers and so far no major ruling has been made defining it as illegal.

[@KaiPetro]

When it would likely become illegal is if you use the collected data for other commercial usage not approved by the owner. But that would apply even if you are manually visiting each page and copy pasting the data into an excel sheet to sell it.

Great video! How could one go about scraping password-protected sites in this fashion? Because whenever I try to access apis of such sites by opening them in a new tab I only get an error message saying that I'm not authorized to do so.

[@isurujn]

New to your channel. I really like your videos. Straight to the point with no fluff. I've always had a bit of a weird habit of running apps through packet sniffers just to see their API requests. I found it fascinating. Although I never really did anything with them. I've noticed that many modern websites like Instagram dynamically load data in a weird way that that cannot be seen using the inspector. Do you have a video on this?

[@TheCameltotem]

Well client side apps with an api is really easy like you shown, usually its server side pages where you can't grab the data from any api or xml request, so you really have to scrape whatever data between the html elements you get.

[@futuregootecks]

Thanks for this! This is exactly what I needed!

Assume this relies on the site being a spa and having json sent? I'm looking at a site that seems to respond with html :/ Think that would also apply to SSR sites, right?

with the websites i try to scrape, i can find interesting "responses" like you've mentioned by monitoring network traffic, but when i try to directly access that API request URL in my browser, I will encounter variations of this: ""message": "403 Forbidden - Valid API key is required"".... does this just mean my target websites are intentionally preventing webscrapers from accessing them in this way?

If you have the curl to get new cookies or keys, why not make that call as part of your script and update the cookies when you get 401?

[@Mars.2024]

I have one more question: Do we need to get permission from any website or contact them via email before webscapping of their content? Sometimes their guidelines and terms of use are vague. Do you take permission your videos? I ask because I want to use their data to feed into a RAG project to use as a vector data repository for semantic search for ai.

[@hurtado-w9c]

Unless OpenAI or some other LLM provider loses a lawsuit for scrapping publicly available data, I doubt it should be an issue.

[@jonrogers694]

Yes you absolutely need to get permission. This is their site, they built it, it's their data not yours. "How I STEAL data from 99% of sites" is the correct title for this video... What a scum you are, John. Build your own app instead of basing it on theft.

[@KaiPetro]

Technically scrapping itself is fine if you are using publicly available data and not using stolen or leaked keys. The opinion is based on the ruling won by youtube-dl where the judgement was there was nothing wrong in saving the videos as long as the purpose is the same. The part to consider is whether to use it for other commercial use. Then it's better to consider a lawyer or reach out to the company for access to their data. Especially if GDPR or other similar laws might apply they have to ensure certain protections such as delete data on request. That cannot be satisfied if they are giving it out to companies to train their models on. But again I don't know if they would apply data being accessible to the general public, so consider based on your circumstances.
