Is there a way to get the list of IDs of all Scratch projects via Scratch API?

No, that would be way to long… Anyway, the project IDs just go sequentially up from 104 to ~198 million, not counting all the deleted projects in between.

By the way, you can get the total number of projects by using /projects/count/all. (This isn't quite live, but updates fairly frequently.)

Thanks. That was helpful. I need to perform analysis on large number of projects so maybe I can generate numbers between 104 to 198 million and then check individual projects.

Slightly relevant thing of mine. It tries random project IDs until it gets a match.

Yes, see here: https://github.com/joker314/joker314.github.io/blob/master/RandomProject.htmlSlightly relevant thing of mine. It tries random project IDs until it gets a match.Is the code available online?

The bit at the start of the URL looks like "https://cors-anywhere.herokuapp.com/" in the code. This basically just fetches the content under the URL that follows; but it bypasses Same Origin policy, something browsers enforce for security, if that helps. Same origin policy stops my code from taking control over your Scratch account.
I'm going to make some modifications to the code since it's a little outdated
(EDIT: done)
To improve, you could try and hook it up to the statistics api so that the maximum random number is the latest one, and not something which turns inaccurate very quickly.

https://projects.scratch.mit.edu/internalapi/project/<project ID>/get/
In it there are md5 hashes of assets such as “8fb3962cfe256cc600587ed3f76f0d59.svg” which you can use to get the assets from
https://cdn.assets.scratch.mit.edu/internalapi/asset/<md5 hash thing>/get/
- Sheep_maker This is a kumquat-free signature. :P
This is my signature. It appears below all my posts. Discuss it on my profile, not the forums. Here's how to make your own.
.postsignature { overflow: auto; } .scratchblocks { overflow-x: auto; overflow-y: hidden; }

Brilliant. Works for 2.0 projects. Any way around for 1.4 projects?Is there a way to get the project code in Json or any other format ?gets the project.json of the given project ID.https://projects.scratch.mit.edu/internalapi/project/<project ID>/get/

Any way around for 1.4 projects?1.4 projects are stored as SB files, which are a particular format which isn't particularly easy to work with (it's not a zip or any similar common format). You can get the SB file just by opening the same URL (cdn.assets.scratch.mit.edu/internalapi/asset/MD5/get/); you can use a library like kurt to extract assets/scripts (but not in the SB2 json format, of course).

Is it possible to tell the version of Scratch project (1.4 or 2.0) or can I fetch the extension of the project via API or any other method.

(Btw, if you're planning to make something that makes lots and lots of requests to the Scratch API to gather lots of statistics, you probably shouldn't go ahead with it, without asking a Scratch Team member first.)

I do intend to make a lots of request. At the moment, I am making only few requests just to analyze few projects but soon will be increasing the number of requests. Is that a problem?

Hi. When I download the project file for 1.4 Scratch projects using https://projects.scratch.mit.edu/internalapi/project/<project ID>/get/ the file I get is in some coded format and there is no md5 in it. I have tried using kurt to read that file but it gives an error. Any idea how to do this?

Any idea how to do this?You might need to give it a .sb extension or pass the format “scratch14” to Kurt: http://kurt.readthedocs.io/en/latest/api.html#kurt.Project.load
Edit: It seems like Kurt won't read any projects from Scratch 1.2 or older because of the ScratchV01 header
Maybe ask @blob8108.Last edited by Jonathan50 (Feb. 12, 2018 04:57:37)

Is there a way to get the age of the user of the project? (via API or any other way?)
