This API is the Metadata API: it gives information about all other available APIs methods, as well as providing human readable and more complete outputs than normal API methods. Some of the information that is returned by the Metadata API:

• the dynamically generated list of all API methods via "getReportMetadata"
• the list of metrics that will be returned by each method, along with their human readable name, via "getDefaultMetrics" and "getDefaultProcessedMetrics"
• the list of segments metadata supported by all functions that have a 'segment' parameter
• the (truly magic) method "getProcessedReport" will return a human readable version of any other report, and include the processed metrics such as conversion rate, time on site, etc. which are not directly available in other methods.
• the method "getSuggestedValuesForSegment" returns top suggested values for a particular segment. It uses the Live.getLastVisitsDetails API to fetch the most recently used values, and will return the most often used values first.

The Metadata API is for example used by the Matomo Mobile App to automatically display all Matomo reports, with translated report & columns names and nicely formatted values. More information on the Metadata API documentation page

The Actions API lets you request reports for all your Visitor Actions: Page URLs, Page titles, Events, Content Tracking, File Downloads and Clicks on external websites. For example, "getPageTitles" will return all your page titles along with standard Actions metrics for each row. It is also possible to request data for a specific Page Title with "getPageTitle" and setting the parameter pageName to the page title you wish to request. Similarly, you can request metrics for a given Page URL via "getPageUrl", a Download file via "getDownload" and an outlink via "getOutlink". Note: pageName, pageUrl, outlinkUrl, downloadUrl parameters must be URL encoded before you call the API.

The Events API lets you request reports about your users' Custom Events. Events are tracked using the Javascript Tracker trackEvent() function, or using the [Tracking HTTP API](https://developer.matomo.org/api-reference/tracking-api).
An event is defined by an event category (Videos, Music, Games...), an event action (Play, Pause, Duration, Add Playlist, Downloaded, Clicked...), and an optional event name (a movie name, a song title, etc.) and an optional numeric value.
This API exposes the following Custom Events reports: getCategory lists the top Event Categories, getAction lists the top Event Actions, getName lists the top Event Names.
These Events report define the following metrics: nb_uniq_visitors, nb_visits, nb_events. If you define values for your events, you can expect to see the following metrics: nb_events_with_value, sum_event_value, min_event_value, max_event_value, avg_event_value
The Events.get* reports can be used with an optional &secondaryDimension parameter. Secondary dimension is the dimension used in the sub-table of the Event report you are requesting.
Here are the possible values of secondaryDimension:

• For Events.getCategory you can set secondaryDimension to eventAction or eventName.
• For Events.getAction you can set secondaryDimension to eventName or eventCategory.
• For Events.getName you can set secondaryDimension to eventAction or eventCategory.

For example, to request all Custom Events Categories, and for each, the top Event actions, you would request: method=Events.getCategory&secondaryDimension=eventAction&flat=1. You may also omit &flat=1 in which case, to get top Event actions for one Event category, use method=Events.getActionFromCategoryId passing it the &idSubtable= of this Event category.

With the parameter '&segment=' you can filter the returned visits by any criteria (visitor IP, visitor ID, country, keyword used, time of day, etc.). The method "getCounters" is used to return a simple counter: visits, number of actions, number of converted visits, in the last N minutes.

The SitesManager API gives you full control on Websites in Matomo (create, update and delete), and many methods to retrieve websites based on various attributes. This API lets you create websites via "addSite", update existing websites via "updateSite" and delete websites via "deleteSite". When creating websites, it can be useful to access internal codes used by Matomo for currencies via "getCurrencyList", or timezones via "getTimezonesList". There are also many ways to request a list of websites: from the website ID via "getSiteFromId" or the site URL via "getSitesIdFromSiteUrl". Often, the most useful technique is to list all websites that are known to a current user, based on the token_auth, via "getSitesWithAdminAccess", "getSitesWithViewAccess" or "getSitesWithAtLeastViewAccess" (which returns both). Some methods will affect all websites globally: "setGlobalExcludedIps" will set the list of IPs to be excluded on all websites, "setGlobalExcludedQueryParameters" will set the list of URL parameters to remove from URLs for all websites. The existing values can be fetched via "getExcludedIpsGlobal" and "getExcludedQueryParametersGlobal". See also the documentation about Managing Websites in Matomo.
