Jikan/MyAnimeList 504 Time-out

[Akamaru]

It seem the Jikan API can't connect to MyAnimeList:

I know you can't fix this. I just want to inform other users looking for this issue.
There is already an open issue at the Jikan Repo: jikan-me/jikan-rest#610

[Fribb]

Yeah, Jikan has a lot of issues with 504 errors by not being able to reach MyAnimeList.

But you could try something by switching to Tenrai as an API alternative.

When you go into

MyAnimeList.bundle/Contents/Code/utils/jikan.py

Line 7 in bd9b79d

API_MAIN = "https://api.jikan.moe/v4"

And change that to https://api.tenrai.org/v1, this might be able to get resolved for now.

Tenrai should be a 1:1 replacement for what the current Metadata Agent uses. So, maybe that would be a good workaround for now.

[Akamaru]

Hm, thats strange. The plugin throws a 403:

But when I open https://api.tenrai.org/v1/anime?q=Ushiro+no+Shoumen+Kamui-san in my browser it works.
Does this API needs headers? It says no: https://api.tenrai.org/documentation#description/auth-rate-limits

[Fribb]

Hmm, the response code is 403: Forbidden, so the API didn't like the request for some reason. I initially thought that it might be because the Agent doesn't set a user agent in the request headers, but even leaving that in Insomnia to test the request still produces a response.

I asked the maintainer on Discord about it.

[Fribb]

@Akamaru can you try again? The maintainer said that it should be fixed now. I changed my Agent to the Tenrai API as well and did a fix match on a show, and it worked there as well.

[Akamaru]

Yes, it works now. Thank you!
I think you should switch to this API. Because in the issue I linked in the top post, someone said the Jikan API will be discontinued on October 1, 2026.
I don't have Discord, so I can't confirm this.

[Fribb]

Yes, I am aware of that. The Public Jikan API will be shut down on October 1, 2026.

Unless you, or anyone reading this, does the change mentioned above, the Agent will still use the Jikan API for all of the requests. I will not be updating the Agent to that API as an Update that you will be able to download. The reason for that is quite simple. While Plex has deprecated the Plugin system for a long time now, they did announce the discontinuation of the 3rd party Plugins (like the metadata agents) in the current form. IIRC, they also said that they want to remove the whole old system "sometime 2026".

The new Metadata System is already available, like the NFO agents.
I am also currently in the process of developing the new Metadata Provider, which will then use the Tenrai API instead of Jikan. But progress is slow in that regard. I hope I can spend more time on this next month when I am on my holiday break. I assume I will get a working first version of it up and running.

This will not work the same way as this metadata agent, but will be a standalone application that you need to install and that Plex will request data from (so basically, the new Metadata Provider will be an API that responds when Plex is requesting the metadata from it). But this will then all be explained when I finally create the repository for it.
