# Interface

How the universal profile exposes the hidden catalog to the provider. Absent or `wrappers`: the `tool_search` and `tool_exec` tools. `code_mode`: one `tool_code` tool that runs a short JavaScript program in which `search()` and `call()` reach the catalog, so several searches and calls complete in one tool result. Experimental.

## Example Usage

```typescript theme={null}
import { Interface } from "@openrouter/sdk/models";

let value: Interface = "wrappers";

// Open enum: unrecognized values are captured as Unrecognized<string>
```

## Values

```typescript theme={null}
"wrappers" | "code_mode" | Unrecognized<string>
```
