# TraceConfig

Metadata for observability and tracing. Known keys (trace\_id, trace\_name, span\_name, generation\_name, parent\_span\_id) have special handling. Additional keys are passed through as custom metadata to configured broadcast destinations.

## Example Usage

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

let value: TraceConfig = {};
```
