		Use:   "api <endpoint>",
		Short: "Make an authenticated request to the GitLab API.",
		Long: heredoc.Docf(`
		Makes an authenticated HTTP request to the GitLab API, and prints the response.
		Specify either a path to a GitLab API v4 endpoint, or %[1]sgraphql%[1]s to access the
		GitLab GraphQL API.

		For more information, see:

		- [GitLab REST API documentation](https://docs.gitlab.com/api/)
		- [GitLab GraphQL documentation](https://docs.gitlab.com/api/graphql/)

		If the current directory is a Git directory, this command uses the GitLab
		authenticated host in the current directory. Otherwise, %[1]sgitlab.com%[1]s is used.
		To override the GitLab hostname, use %[1]s--hostname%[1]s.

		When used in the endpoint argument, these placeholder values are replaced
		with values from the repository of the current directory:

		- %[1]s:branch%[1]s
		- %[1]s:fullpath%[1]s
		- %[1]s:group%[1]s
		- %[1]s:id%[1]s
		- %[1]s:namespace%[1]s
		- %[1]s:repo%[1]s
		- %[1]s:user%[1]s
		- %[1]s:username%[1]s

		The default HTTP request method is %[1]sGET%[1]s when no parameters are added,
		and %[1]sPOST%[1]s otherwise. To override the method, use %[1]s--method%[1]s.

		Pass one or more %[1]s--raw-field%[1]s values in %[1]skey=value%[1]s format to add
		JSON-encoded string parameters to the %[1]sPOST%[1]s body.

		The %[1]s--field%[1]s flag behaves like %[1]s--raw-field%[1]s but converts values
		based on their format:

		- Literal values %[1]strue%[1]s, %[1]sfalse%[1]s, %[1]snull%[1]s, and integer numbers are converted to
		  the matching JSON types.
		- Placeholder values %[1]s:namespace%[1]s, %[1]s:repo%[1]s, and %[1]s:branch%[1]s are populated with values
		  from the repository of the current directory.
		- If the value starts with %[1]s@%[1]s, the rest of the value is interpreted as a
		  filename to read the value from. Pass %[1]s-%[1]s to read from standard input.

		Neither %[1]s--field%[1]s nor %[1]s--raw-field%[1]s parses JSON arrays or objects;
		those values are sent as strings. To pass a JSON body literally, use %[1]s--input%[1]s.

		For GraphQL requests, all fields other than %[1]squery%[1]s and %[1]soperationName%[1]s are
		interpreted as GraphQL variables.

		To send data as %[1]smultipart/form-data%[1]s instead of JSON, use %[1]s--form%[1]s. This is
		required for API endpoints that accept file uploads, such as wiki attachments.
		Pass one or more %[1]s--form%[1]s values in %[1]skey=value%[1]s format. To upload a file,
		prefix the value with %[1]s@%[1]s followed by the file path. Pass %[1]s-%[1]s to read from
		standard input. Do not combine %[1]s--form%[1]s with %[1]s--field%[1]s, %[1]s--raw-field%[1]s, or %[1]s--input%[1]s.

		To pass a raw request body, use %[1]s--input%[1]s with a file path. Pass %[1]s-%[1]s to
		read from standard input. In this mode, parameters specified with %[1]s--field%[1]s
		flags are serialized into URL query parameters.

		In %[1]s--paginate%[1]s mode, all pages of results are requested sequentially until
		no more pages of results remain. For GraphQL requests:

		- The original query must accept an %[1]s$endCursor: String%[1]s variable.
		- The query must fetch the %[1]spageInfo{ hasNextPage, endCursor }%[1]s set of fields from a collection.

		The %[1]s--output%[1]s flag controls the output format:

		- %[1]sjson%[1]s (default): Pretty-printed JSON. Arrays are output as a single JSON array.
		- %[1]sndjson%[1]s: Newline-delimited JSON, also known as JSON Lines. Each array element
		  or object is output on a separate line. This format is more memory-efficient for
		  large datasets and works well with tools like %[1]sjq%[1]s.

		For ndjson format specifications, see the
		[ndjson spec](https://github.com/ndjson/ndjson-spec) and [JSON Lines](https://jsonlines.org/).
