# ShadowedBy

What egress uses instead of this installation for a request to its account: an earlier installation on the same account, or a token pinned to the account. Null when this installation answers.

## Example Usage

```go theme={null}
import (
	"github.com/OpenRouterTeam/go-sdk/models/components"
)

value := components.ShadowedByInstallation

// Open enum: custom values can be created with a direct type cast
custom := components.ShadowedBy("custom_value")
```

## Values

| Name | Value |
| - | - |
| `ShadowedByInstallation` | installation |
| `ShadowedByToken` | token |
