## List supported cloud vendors and regions

`client.Cache.OriginCloudRegions.SupportedRegions(ctx, query) (*OriginCloudRegionSupportedRegionsResponse, error)`

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

Returns the cloud vendors and regions that are valid values for origin cloud region mappings. Each region includes the Tiered Cache upper-tier colocation codes that will be used for cache routing when a mapping targeting that region is active. Requires the zone to have Tiered Cache enabled.

### Parameters

- `query OriginCloudRegionSupportedRegionsParams`

  - `ZoneID param.Field[string]`

    Identifier.

### Returns

- `type OriginCloudRegionSupportedRegionsResponse struct{…}`

  Cloud vendors and their supported regions for origin cloud region mappings.

  - `ObtainedCodes bool`

    Whether Cloudflare airport codes (IATA colo identifiers) were successfully resolved for the `upper_tier_colos` field on each region. When `false`, the `upper_tier_colos` arrays may be empty or incomplete.

  - `Vendors map[string, []OriginCloudRegionSupportedRegionsResponseVendor]`

    Map of vendor name to list of supported regions.

    - `Name string`

      Cloud vendor region identifier.

    - `UpperTierColos []string`

      Cloudflare Tiered Cache upper-tier colocation codes co-located with this cloud region. Requests from zones with a matching origin mapping will be routed through these colos.

### 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"),
  )
  response, err := client.Cache.OriginCloudRegions.SupportedRegions(context.TODO(), cache.OriginCloudRegionSupportedRegionsParams{
    ZoneID: cloudflare.F("023e105f4ecef8ad9ca31a8372d0c353"),
  })
  if err != nil {
    panic(err.Error())
  }
  fmt.Printf("%+v\n", response.ObtainedCodes)
}
```
