## List origin cloud region mappings

`client.Cache.OriginCloudRegions.List(ctx, query) (*OriginCloudRegionListResponse, error)`

**get** `/zones/{zone_id}/cache/origin_cloud_regions`

Returns all IP-to-cloud-region mappings configured for the zone. Each mapping tells Cloudflare which cloud vendor and region hosts the origin at that IP, enabling the edge to route via the nearest Tiered Cache upper-tier co-located with that cloud provider. Returns an empty array when no mappings exist.

### Parameters

- `query OriginCloudRegionListParams`

  - `ZoneID param.Field[string]`

    Identifier.

### Returns

- `type OriginCloudRegionListResponse struct{…}`

  Response result for a list of origin cloud region mappings.

  - `ID OriginCloudRegionListResponseID`

    - `const OriginCloudRegionListResponseIDOriginPublicCloudRegion OriginCloudRegionListResponseID = "origin_public_cloud_region"`

  - `Editable bool`

    Whether the setting can be modified by the current user.

  - `Value []OriginCloudRegion`

    - `OriginIP string`

      The origin IP address (IPv4 or IPv6, canonicalized).

    - `Region string`

      Cloud vendor region identifier.

    - `Vendor OriginCloudRegionVendor`

      Cloud vendor hosting the origin.

      - `const OriginCloudRegionVendorAws OriginCloudRegionVendor = "aws"`

      - `const OriginCloudRegionVendorAzure OriginCloudRegionVendor = "azure"`

      - `const OriginCloudRegionVendorGcp OriginCloudRegionVendor = "gcp"`

      - `const OriginCloudRegionVendorOci OriginCloudRegionVendor = "oci"`

    - `ModifiedOn Time`

      Time this mapping was last modified.

  - `ModifiedOn Time`

    Time the mapping set was last modified. Null when no mappings exist.

### Example

```go
package main

import (
  "context"
  "fmt"

  "github.com/cloudflare/cloudflare-go"
  "github.com/cloudflare/cloudflare-go/cache"
  "github.com/cloudflare/cloudflare-go/option"
)

func main() {
  client := cloudflare.NewClient(
    option.WithAPIToken("Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY"),
  )
  originCloudRegions, err := client.Cache.OriginCloudRegions.List(context.TODO(), cache.OriginCloudRegionListParams{
    ZoneID: cloudflare.F("023e105f4ecef8ad9ca31a8372d0c353"),
  })
  if err != nil {
    panic(err.Error())
  }
  fmt.Printf("%+v\n", originCloudRegions.ID)
}
```
