Hi
Alamin
, Thanks for catching this! I was able to replicate the behavior you're seeing, have identified the issue, and have opened a bug report (
phab:T390317
). I expect we'll be able to get a fix out next week; I'll post again here to confirm once the fix is deployed. In the meantime, you can access the feed endpoints through the wiki URLs. For example:

The endpoint example for curl, Python, PHP, JavaScript are not being shown. The title is there but the example endpoints are not visible. Actually, it shows up for a few milliseconds at the beginning of page load, but then it vanishes. Here is a screenshot of where the problem is:

Announcement: API Portal shutdown

The Wikimedia Foundation has decided to shut down the API Portal wiki as part of a new
strategy for Wikimedia APIs
. We’re still working on exact plans and schedules, but here is a general idea of what to expect:
Endpoints
: api.wikimedia.org endpoints will continue to work as currently documented until at least June 2026. Starting in the second half of 2026, api.wikimedia.org endpoints will be migrated to new routes and eventually deprecated.
API keys
: Most API keys created through the API Portal will continue to work. You can manage your API keys through
Special:OAuthConsumerRegistration on Meta-Wiki
Docs
: Documentation from the API Portal will be consolidated and moved to other technical documentation wikis.
We’ll be providing more details about the planned shut down in the next couple of months. To get the latest updates, add this page to your
watchlist
or subscribe to the
mediawiki-api-announce mailing list
. We’d like to thank everyone who has contributed to the API Portal for being part of this community! We hope you'll continue to follow API projects in the future.
Background
In 2020, the Wikimedia Foundation Platform Engineering Team wanted to create a home for Wikimedia API docs that was similar to other popular API docs sites, and that allowed developers to more easily create and manage API keys.
Building the API Portal as a standalone wiki benefits from the advantages of MediaWiki:
Ease of editing
Ability to translate content
Community collaboration through talk pages, watchlists, and other features
However, using a standalone wiki for the API Portal also has disadvantages:
Administration
: Each new wiki needs a community of administrators, page patrollers, and other functionaries. A new wiki adds work for the Wikimedia technical community.
Technical complexity
: MediaWiki is a complex ecosystem. Since the API Portal works differently from other Wikimedia wikis, we often find bugs that come from interactions with extensions, skins, and other wikis.
Visual inconsistency
: The API Portal’s simplified visual design makes it difficult to access wiki features like special pages. In addition, global skin preferences can override the API Portal’s visual design entirely, making the site difficult to use.
Wikimedia Foundation’s Product Management, MediaWiki Interfaces, and Tech Docs teams have decided that the disadvantages of implementing the API Portal as a standalone wiki outweigh the advantages. In 2026, we’ll be working on plans to overcome these disadvantages and reimagining ways to make API docs easy to find, use, and create. --

Hi all, Here's an update on the API Portal shut down:
The API Portal wiki will be inaccessible starting in June 2026.
To learn about Wikimedia APIs and find links to docs, visit the new
landing page
(work in progress) on mediawiki.org.
Starting in late March or early April 2026, api.wikimedia.org endpoints will have the same
rate limits
as other Wikimedia APIs. The new rate limits are higher than the
current rate limits
, so this change should not create any issues. The Lift Wing API will continue to have the same
custom rate limits
with only minor clarifications.
For a timeline and the latest project information, see the
project page

mostread missing from API result
Latest comment:

Hi! I've been querying API daily since the start of 2026, specifically for the 'mostread' key in the result. But it seems like this has been missing since 2026/03/02 and onwards. The last available result that contains this key is for 2026/03/01. Did anything change here? Is this a result of the upcoming sunset of this API?
This is the endpoint i've been hitting:
"https://api.wikimedia.org/feed/v1/wikipedia/{lang}/featured/{y}/{m}/{d}"
Keys that were being returned on 2026/03/01 (and prior): dict_keys(['tfa', 'mostread', 'image', 'onthisday'])
Keys that are being returned on 2026/03/02 (and after): dict_keys(['tfa', 'image', 'onthisday']) -- 'mostread' is missing
Thanks!

Hi @
Cholo5ntrol
, thanks for reporting this! mostread isn't available for the current date in UTC, but it should be available for 2026/03/02. I've opened a bug report here:
phab:T418894
. This shouldn't be related to the upcoming deprecation, but I'll comment back here when there's an update.

In the meantime, you can also call the Wikimedia Analytics API to
list the most-viewed pages
for a given day.

Hi @

, The fix was deployed! I tested the app authentication flow locally, and I was able to get a valid token, so hopefully the issue is fixed for you as well. Let me know if you run into any other issues!
