• only have one slug editing-basics but this is the message i am getting.

also i have a few questions regarding the Wiki API and pagination:

1 - does the Wiki API always return a continue key when there are more than 500 linked pages? If not, how is pagination handled? This PR assumes that theres an api key continue.
2 - i used Postman to check for the presence of a continue key in the API response but was not able to get the output. how can I better inspect the API response or debug it? Are there any tools or methods you'd recommend for troubleshooting?
3 - Can you suggest any improvements for error handling or pagination logic in the current implementation?

Thanks !
