# ModelCredentialKey

One API key of a credential. The keys are tried in their order.

**Kind:** an object, used in responses.

## Fields

Every field is present in a response; empty ones are `null`.

| Field | Type | Description |
|---|---|---|
| `id` | `uuid` | Stable across edits, so a key can be kept, moved or removed without sending it again. |
| `keyHint` | `string` | The key's last four characters, so keys can be told apart without the key being served. |
| `addedAtUtc` | `datetime` |  |

## Example

```json
{
  "id": "3f2b8c1e-5d4a-4e6b-9c7d-2a1b0c9d8e7f",
  "keyHint": "...",
  "addedAtUtc": "2026-10-26T12:00:00.0000000Z"
}
```
