The map key is the HTTP method with the same capitalization that is to be sent in the request. This map MUST NOT contain any entry for the methods that can be defined by other Operation Object fields (e.g. no `POST` entry, as the Operation Object field `post` is used for this method). |
 | <a name="path-item-servers"></a>servers | [[Server Object](#server-object)] | An alternative `servers` array to service all operations in this path. If a `servers` array is specified at the [OpenAPI Object](#oas-servers) level, it will be overridden by this value. |
 | <a name="path-item-parameters"></a>parameters | [[Parameter Object](#parameter-object) \| [Reference Object](#reference-object)] | A list of parameters that are applicable for all the operations described under this path. These parameters can be overridden at the operation level, but cannot be removed there. The list MUST NOT include duplicated parameters. A unique parameter is defined by a combination of a [name](#parameter-name) and [location](#parameter-in). The list can use the [Reference Object](#reference-object) to link to parameters that are defined in the [OpenAPI Object's `components.parameters`](#components-parameters). |
