@slishnevsky I am sorry. We had to disable HTML content because of phishing attacks through our server. Currently, only JSON, XML and CSV are allowed.

Any chance it will return? Your proxy is perfect for small local projects.

Hey there @mariusbolik,

I noticed that there's some rate limiting occurring recently. Not sure if there was already rate limiting before your update after the phishing attacks, but when I make around 50ish requests through the proxy, I start getting 403s on all my requests. I'm thinking that's being returned from corsproxy.io, would you be able to confirm that?

I'm really liking corsproxy.io so far, I'm using it in a small project for a client and for my own personal project. I believe I created an account linked with my Github, but I don't know if I'm signed up for the analytics dashboard and news on the paid service. Would love to get in on that if possible. Can you provide any more information on that?

Danke!

This
https://corsproxy.io/?https%3A%2F%2Fwww.eurocontrol.int%2Fperformance%2Fdata%2Fdownload%2Fcsv%2Fmom_co2.csv
for a CSV fails with

{
"message": "Please create an account at https://accounts.corsproxy.io to proxy this file type."
}

I am using it in Observable in this notebook

Any idea about what I am doing wrong? This used to worked for months...

PS: I created an account but what do I use it for?

@mariusbolik do you think you could add a new feature to corsproxy.io to parse a 404 response to 200?

Hey guys any way to iframe youtube website ? ( not a single video but the whole website ? )

Hey guys any way to iframe youtube website ? ( not a single video but the whole website ? )

I’m pretty sure just putting the YouTube URL in the src field of an iframe will work, as iframes do not have the same cross-origin limitations as web requests. Otherwise, you can GET the HTML code of the site using the proxy and set that as the srcdoc property of an iframe. Keep in mind that a lot of dynamic features of the website will not work.

Just curious, why are you iframing an entire website?

I don't think so. Google makes its sites so that they cannot run in iframes.

I don't think so. Google makes its sites so that they cannot run in iframes.

Me and many other people have pulled video data from the raw HTML of YouTube sites without issue (you just need to use a CORS proxy like the ones here), however I’m not sure if this works for OP’s situation.

seems these days you have to recompile firefox to stop nagging you about this garbage, certainly cheaper than paying somebody for this, specially if you're the only user

A lot of these either don't work, need you to put the URL in query parameters (which complicates things on my API client), and/or don't pass on the query parameters of your URL (corsproxy.io). I am trying to make an OAI-PMH client for the web, most of these don't send the appropriate headers and aren't even HTTPS.
Just wanted to leave my thoughts and how I wound up here.

Thank you all for using CorsProxy.io extensively! We see a significant growth in the number of users and daily requests. But we are also noticed suspicious content that was proxied through our service, so we hat to block all content types that are not text based. Our service should be used mainly for JSON, CSV, XML, etc. We have also blocked some countries due to a high volume of suspicious requests to ensure the security and integrity of our service. If you receive a notification that you've been blocked, it's likely due to our rate limiting measures being triggered to maintain service integrity.

This is rather unfortunate as content types like images will not be supported (and should be reflected in the summary table).

@slishnevsky I am sorry. We had to disable HTML content because of phishing attacks through our server. Currently, only JSON, XML and CSV are allowed.

why it is showing the error in India?

I mean users can just steal your key for cors lol

@reynaldichernando

@Kreijstal, thanks for the comment, you are right and that's a fair assessment
I thought about this specifically, so I made it that for each application (api key), it is only usable for the specified allowed origins and allowed URLs (remote resources)

so even though the api key is passed through the client side, it is only usable for your website, and the target resource you are fetching

happy to answer any additional comments or questions!

Hi everyone, sharing some update for Corsfix based on the feedbacks

  • Removed API key
    • This was unnecessary, plus I agreed with the feedback by Kreijstal
    • The proxied requests will be validated only by the Origin and the target URLs
  • Free for development
    • There are some good options for self-hosting CORS proxy like Cloudflare
    • However if you don't want to go through the whole setup, and need to just start proxying immediately, you can use Corsfix for free for development
  • Free for open source
  • Unlimited monthly requests
    • Since websites can get tons of requests anyway, I’m ditching the credit system and making it unlimited

That's all, thank you and hope these changes make it easier for everyone to try Corsfix!
