[Bug Report] API_ERROR 429 with MD_DISC_TRACK_TOTALS and MD_SAVE_GENRES

[P4R4NORM4L]

What I’m asking for

A clear setup guide
Do we need a Spotify dev app to make this work?
How does it know we have a premium spotify account vs non premium?

Right now it’s easy to get logged in but still be stuck with API errors and no clear next step.

My setup

• OS: Windows
• Install method:

  pipx install git+https://github.com/Googolplexed0/zotify.git

• Spotify Developer app: Development mode
• Redirect URI:
  • http://127.0.0.1:4381/login

What works

OAuth login works. zotify prints a login link that includes:

• redirect_uri=http://127.0.0.1:4381/login

What doesn’t work (main problem)

After login, any track query fails with repeated 429 and then crashes.

Command:

zotify --client-id <my_client_id>
zotify -l

Output:

###   WARNING:  API ERROR - RETRYING   ###
###   Status 429:  Received an empty response   ###

ValueError: No Metadata Fetched

I also saw:

{
  "error": {
    "status": 401,
    "message": "No token provided"
  }
}

What I tried

• Deleted credentials file and re-logged in
• Slowed config values (rate limiter / wait time)
• Disabled extra metadata (genres/lyrics)
• Still always get 429 → crash
• Where do I get this token?

Got it to work by turning these options to false
"MD_DISC_TRACK_TOTALS": "False",
"MD_SAVE_GENRES": "False",

Weird

You seem to have the right setup. I've also been getting the 429 status code error running the same setup I used to use without issue. Maybe Spotify quietly decreased the api rate limit very recently?

From what I understand, MD_DISC_TRACK_TOTALS gets the total tracks on a album by parsing through all the tracks on the album which make a lot more api calls than normal. Could be wrong on that though. I assume turning it off cuts out a ton of api calls and helps zotify not reach the rate limit. Unfortunately my account just got the 429 and will be timed out for 24 hours so I can't help confirm that setting MD_DISC_TRACK_TOTALS to false helps haha but it makes sense to me. Dont know if MD_SAVE_GENRES makes a difference though.

No.

File "C:\Users\USER\pipx\venvs\zotify\Lib\site-packages\zotify\api.py", line 1646, in execute
self.fetch_extra_metadata()
~~~~~~~~~~~~~~~~~~~~~~~~~^^

If you are reaching this point, then you are able to fetch metadata successfully. The errors must be related to the API and outside of this library's control.

From what I understand, MD_DISC_TRACK_TOTALS gets the total tracks on a album by parsing through all the tracks on the album which make a lot more api calls than normal.

MD_DISC_TRACK_TOTALS (and also DOWNLOAD_PARENT_ALBUM) will make an API call for every album (that hasn't been directly called already). MD_SAVE_GENRES will make an API call for every artist (that hasn't been directly called already). Turning them off will significantly decrease the number of API calls made.
