WikiWatcher

WikiWatcher is an API for retrieving data about the history of edits made to an article or by a user on Wikipedia. Endpoints include:

1. /articleHistory/title - Requires the title of an article.
By default, retrieves the 10 most recent revisions made to the article.
Optional parameters:
• startyear
• startmonth
• startday
• starthour
• startminute
• startsecond
startx parameters specify a date and time which acts as a lower bound on the timestamp of retrieved revisions. Date/time parameters, if specified, must be supported by all units of time greater than themselves -
i.e. if a month is specified, a year must also be specified. If a day is specified, a month and a year must also be specified, etc.
Times are to be specified in 24-hour format, from hour 0 through 23.
If a time is before the first existing edit or after the present day, the nearest valid date/time will be used.
• endyear
• endmonth
• endday
• endhour
• endminute
• endsecond
endx parameters specify a date and time which acts as an upper bound on the timestamp of retrieved revisions. These date/time parameters follow the same specificity rules as those in the endpoints above.
• tags
tags should be a comma-separated bracket-enclosed list of strings matching wikipedia's available reviser-applied tags for revisions.
Single tags still require the enclosing brackets.

	<li>user - retrieve only revisions to the specified article which were created by this username.</li>

	valid values for this argument:
	<ul>
		<li>revisions_per_time - plots the number of revisions per unit of time as a histogram.</li>
		<li>revisions_per_user - plots the proportion of revisions made to the article per user who has made revisions as a pie chart.</li>

<br/>
<li>/compareRevisions/title - Requires the title of an article.</li>
	Parameters:
	<ul>
	At least a startyear and an endyear are required. Remaining parameters are optional.

The API is intended to facilitate or ease the development of applications which use the data it returns. We hope to include a small toy example of such an application once the API itself is in a client-ready state, or potentially a graphical frontend which will replace this page (while still making the readme accessible through a separate link/url).

The API is implemented using the Flask framework for Python.
