MediaWiki API help

Which action to perform.

The format of the output.

Maximum lag can be used when MediaWiki is installed on a database replicated cluster. To save actions causing any more site replication lag, this parameter can make the client wait until the replication lag is less than the specified value. In case of excessive lag, error code maxlag is returned with a message like Waiting for $host: $lag seconds lagged.
See Manual: Maxlag parameter for more information.

Set the s-maxage HTTP cache control header to this many seconds. Errors are never cached.

Any value given here will be included in the response. May be used to distinguish requests.

Include the hostname that served the request in the results.

Include the current timestamp in the result.

When accessing the API using a cross-domain AJAX request (CORS), set this to the originating domain. This must be included in any pre-flight request, and therefore must be part of the request URI (not the POST body). This must match one of the origins in the Origin header exactly, so it has to be set to something like https://en.wikipedia.org or https://meta.wikimedia.org. If this parameter does not match the Origin header, a 403 response will be returned. If this parameter matches the Origin header and the origin is whitelisted, an Access-Control-Allow-Origin header will be set.

Reason for block.

Block anonymous users only (i.e. disable anonymous edits for this IP address).

Prevent account creation.

Automatically block the last used IP address, and any subsequent IP addresses they try to login from.

Prevent user from sending email through the wiki. (Requires the blockemail right).
