This is just a preliminary examining of what kind of e.g. coding it takes to send text with a image to a microblogging service where one might want to share something that was published. At least for Mastodon and Bluesky, the user would be required to create a user account, of course, and also to create an application in the settings of such to which a message can be sent for publishing programmatically (via an API).

Creating an application in the settings of a microblogging service is not a difficult operation in itself. It mainly requires giving it a name, after which an apikey or similar gets generated and which should then be stored to user settings of the publishing application.

It was also examined how readable the developer documentations are and if they leave many open questions.

Not necessarily relevant to a user of the publishing application, but some may be interested about the amount of code required to post to these microblogging services. Here are a couple of code snippets to give some idea.
