## List supported cloud vendors and regions

`cache.origin_cloud_regions.supported_regions(OriginCloudRegionSupportedRegionsParams**kwargs)  -> OriginCloudRegionSupportedRegionsResponse`

**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

- `zone_id: str`

  Identifier.

### Returns

- `class OriginCloudRegionSupportedRegionsResponse: …`

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

  - `obtained_codes: 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: Dict[str, List[Vendor]]`

    Map of vendor name to list of supported regions.

    - `name: str`

      Cloud vendor region identifier.

    - `upper_tier_colos: List[str]`

      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

```python
import os
from cloudflare import Cloudflare

client = Cloudflare(
    api_token=os.environ.get("CLOUDFLARE_API_TOKEN"),  # This is the default and can be omitted
)
response = client.cache.origin_cloud_regions.supported_regions(
    zone_id="023e105f4ecef8ad9ca31a8372d0c353",
)
print(response.obtained_codes)
```
