Hi everyone,

If you are using Wikidata's APIs please see the information below. The WMF will start enforcing the user agent policy more strictly going forward. So if you have a tool or application that doesn't set a proper user agent please take a minute to fix that.

Cheers Lydia

Hi,

As part of our work to ensure a fair use of our infrastructure[1], we are going to progressively enforce our long-standing user-agent policy[2] more systematically than we used to.

This will mean that, unless you set a user-agent that complies with the policy, your requests will be rate-limited and eventually blocked over the coming month. As usual, this excludes requests coming directly from toolforge/wikimedia cloud services.

For details on the schedule and further discussion please refer to the phabricator task[3]

Cheers,

Giuseppe
