Not being able to upload from skeb

When I try to upload anything from skeb, it keeps failing with an error message like "Upload failed: https://skeb.jp/@wobumi/works/16 doesn't contain any images." even if I try one of the posts from skeb already uploaded here which definitely have images. Tried Chrome and Firefox and both had the same problem. Any way to fix it?

For this platform I just download and upload the image, then use the link as a source.

You can use the direct image URL to upload. It'll even automatically link to the Skeb page on upload without the need to change the link manually. I personally use the Upload to Danbooru extension to right-click the image and upload. What it won't do is grab any commentary...

Skeb uploading is currently broken, see issue #5773 on github

@Alixiron If you want to get your images unwatermarked you can do this with one simple trick

Extract your Skeb creds

• Open any Skeb.jp page
• Ensure you're logged in
• Open dev tools in your browser, for example by clicking F12 in Chrome or Firefox
• From local storage copy the value of token property, example
• From cookies copy the value of request_key cookie, example

Get the unwatermarked image

In order to do it automatically you will need a help of your system to call Skeb API.

Here is a curl query template which gets the response with the unwatermarked image URL

curl https://skeb.jp/api/users/<skeb_artist_name>/works/<commission_number> -H 'Authorization: Bearer <your_extracted_token>' -H 'Cookie: request_key=<your_extracted_request_key>' -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36'

Notice that the URL after curl keyword is not an URL to the web page, it points to API. For example https://skeb.jp/@usumeshirouchan/works/65 (webpage) becomes https://skeb.jp/api/users/usumeshirouchan/works/65 (API call).
User-Agent part is a random, but valid source of the request, it's necessary to represent yourself as a web browser.
After all is said and done a real query can look like this:

curl https://skeb.jp/api/users/usumeshirouchan/works/65 -H 'Authorization: Bearer eyJhbGciOiJSUzI1NiJ9.eyJkYXRhIjp...' -H 'Cookie: request_key=fb58e6fc:aed...' -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36'

Use system console

Here are useful one-line scripts in Powershell (built natively in Windows)

Get unwatermarked image URL

curl https://skeb.jp/api/users/<skeb_artist_name>/works/<commission_number> -H 'Authorization: Bearer <your_extracted_token>' -H 'Cookie: request_key=<your_extracted_request_key>' -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36' | ConvertFrom-Json -AsHashtable | Select-Object -ExpandProperty 'article_image_url'

Copy paste the link in output and download it from your browser.

For Linux I guess you can Bash and replace the pipeline | ConvertFrom-Json -AsHashtable | Select-Object -ExpandProperty 'article_image_url' with | jq -r '.article_image_url' but I didn't test it myself.

Download unwatermarked image

curl (curl https://skeb.jp/api/users/<skeb_artist_name>/works/<commission_number> -H 'Authorization: Bearer <your_extracted_token>' -H 'Cookie: request_key=<your_extracted_request_key>' -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36' | ConvertFrom-Json -AsHashtable | Select-Object -ExpandProperty 'article_image_url') -o "<output_path>"

output_path is a target path to the file in your system, for example "C:/Test/output.jpg", the image will be saved as such.
My local results

Use Postman

Alternatively to system console you can download Postman program and use it to call the API.
Open a new tab, paste the API url, fill the headers with creds, click Send button and that's it. Example
CTRL + click the link and it opens in your browser.

Upload the file to Danbooru

- Copy paste the webpage link as a source
- Copy paste the commentary
- Tag meticulously
- Don't forget about skeb commission!
- Post it
- Make the world a better place

Remarks

It's enough to configure it once, after that you only need to replace an artist name & a work number and press Enter.
As always only the first image in a Skeb collection is free of the sample watermark.

This method you describe sounds kind of like an exploit, yeah it's there for the taking but isn't this basically like taking a private / paid image?

Well if its fine, why not.

Not even remotely close. This is literally just using the API, which is like, the normal thing to do.

Had some errors with the curl one for some reason but postman worked like a charm while also being easy to setup following your example. Thanks a lot.

Unwatermarked article_image_url versions have lower quality settings than the watermarked versions (fm=jpg&q=45&w=696) and are not always available. There is some more information about them available at https://github.com/mikf/gallery-dl/issues/1031.
