### HTTP request

Choose an endpoint:
global africa-south1 asia-east1 asia-east2 asia-northeast1 asia-northeast2 asia-northeast3 asia-south1 asia-south2 asia-southeast1 asia-southeast2 asia-southeast3 australia-southeast1 australia-southeast2 europe-central2 europe-north1 europe-north2 europe-southwest1 europe-west1 europe-west10 europe-west12 europe-west2 europe-west3 europe-west4 europe-west6 europe-west8 europe-west9 me-central1 me-central2 me-west1 northamerica-northeast1 northamerica-northeast2 northamerica-south1 southamerica-east1 southamerica-west1 us-central1 us-east1 us-east4 us-east5 us-south1 us-west1 us-west2 us-west3 us-west4   
`GET https://compute.googleapis.com/compute/v1/projects/{project}/zones/{zone}/futureReservations`

<br />

The URLs use [gRPC Transcoding](https://google.aip.dev/127) syntax.

### Path parameters

| Parameters ||
|---|---|
| `project` | `string` Project ID for this request. |
| `zone` | `string` Name of the zone for this request. Name should conform to RFC1035. |

### Query parameters

| Parameters ||
|---|---|
| `maxResults` | `integer (https://developers.google.com/discovery/v1/type-format format)` The maximum number of results per page that should be returned. If the number of available results is larger than `maxResults`, Compute Engine returns a `nextPageToken` that can be used to get the next page of results in subsequent list requests. Acceptable values are `0` to `500`, inclusive. (Default: `500`) |
| `pageToken` | `string` Specifies a page token to use. Set `pageToken` to the `nextPageToken` returned by a previous list request to get the next page of results. |
| `filter` | `string` A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal [AIP-160](https://google.aip.dev/160). These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: labels.owner:* You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on [resource labels](https://docs.cloud.google.com/compute/docs/labeling-resources). To filter on multiple expressions, provide each separate expression within parentheses. For example: (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google [RE2](https://github.com/google/re2/wiki/Syntax) library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions. |
| `orderBy` | `string` Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using `orderBy="creationTimestamp desc"`. This sorts results based on the `creationTimestamp` field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by `name` or `creationTimestamp desc` is supported. |
| `returnPartialSuccess` | `boolean` Opt-in for partial success behavior which provides partial results in case of failure. The default value is false. For example, when partial success behavior is enabled, aggregatedList for a single zone scope either returns all resources in the zone or no resources, with an error code. |

### Request body

The request body must be empty.
