## Fields

| Field | Type | Required | Description | Example |
| - | - | - | - | - |
| `httpReferer` | *string* | ➖ | The app identifier should be your app's URL and is used as the primary identifier for rankings. This is used to track API usage per application.  | |
| `appTitle` | *string* | ➖ | The app display name allows you to customize how your app appears in OpenRouter's dashboard.  | |
| `appCategories` | *string* | ➖ | Comma-separated list of app categories (e.g. "cli-agent,cloud-agent"). Used for marketplace rankings.  | |
| `user` | *string* | ✔️ | Immutable case-sensitive tracking string supplied as user on inference requests or as external.user on API keys: 1 to 512 characters, well-formed Unicode, no NUL, no surrounding whitespace. URL-encode it in resource paths; an ID of `.` or `..` cannot be addressed by path, so look it up with the list filter. | employee\_123 |
