prefix_path	Define the prefix for all operation paths	string	Y
tag	Define a tag for all operations.	string	Y

Operation parameters

Attribute	description	Type	Optional
path	HTTP uri.	string	N
method	HTTP method. The possible values are “get”, “post”, “put”, “delete”, “head”, “options”, “connect”, “patch”, “trace”.	string	N
deprecated	Operation deprecated	bool	Y
tag	Operation tag	Tags	Y
operation_id	Unique string used to identify the operation.	string	Y
transform	Use a function to transform the API endpoint.	string	Y

Operation argument parameters

Attribute	description	Type	Optional
name	Parameter name	string	Y
desc	Argument description	string	Y
deprecated	Argument deprecated	bool	Y
default	Default value	bool,string	Y
validator.multiple_of	The value of “multiple_of” MUST be a number, strictly greater than 0. A numeric instance is only valid if division by this value results in an integer.	number	Y
validator.maximum	The value of “maximum” MUST be a number, representing an upper limit for a numeric instance. If exclusive is true and instance is less than the provided value, or else if the instance is less than or exactly equal to the provided value.	{ value: <number>, exclusive: <bool>}	Y
validator.minimum	The value of “minimum” MUST be a number, representing a lower limit for a numeric instance. If exclusive is true and instance is greater than the provided value, or else if the instance is greater than or exactly equal to the provided value.	{ value: <number>, exclusive: <bool>}	Y
validator.max_length	The value of “max_length” MUST be a non-negative integer. A string instance is valid against this validator if its length is less than, or equal to, the value.	usize	Y
validator.min_length	The value of “min_length” MUST be a non-negative integer. The value of this validator MUST be an integer. This integer MUST be greater than, or equal to, 0.	usize	Y
validator.pattern	The value of “pattern” MUST be a string. This string SHOULD be a valid regular expression, according to the ECMA 262 regular expression dialect. A string instance is considered valid if the regular expression matches the instance successfully.	string	Y
validator.max_items	The value of “max_items” MUST be an integer. This integer MUST be greater than, or equal to, 0. An array instance is valid if its size is less than, or equal to, the value of this validator.	usize	Y
validator.min_items	The value of “min_items” MUST be an integer. This integer MUST be greater than, or equal to, 0. An array instance is valid if its size is greater than, or equal to, the value of this validator.	usize	Y
validator.unique_items	The value of “unique_items” MUST be an boolean. If this value is false, the instance validates successfully. If this value is true, the instance validates successfully if all of its elements are unique.	bool	Y
