When a model is attached to a [reusable credential](./ui_credentials.md), LiteLLM automatically injects the credential name as a tag on every request that uses that model. This means credential-level spend and usage are tracked with zero extra configuration.

# Credential Usage Tracking
When a model is attached to a [reusable credential](./ui_credentials.md), LiteLLM automatically injects the credential name as a tag on every request that uses that model. This means credential-level spend and usage are tracked with zero extra configuration.
## How It Works
When you attach a model to a reusable credential via `litellm_credential_name`, each request routed through that model is tagged `Credential: <name>` (for example, `Credential: xAI`). This tag flows into `DailyTagSpend` and appears in the **Tag** view on the Usage page, where you can filter spend and usage by credential.
If a model has no credential attached, behavior is unchanged—no credential tag is added.
## Viewing Credential Usage
In the Admin UI, go to **Usage → Tag** and look for tags with the `Credential: ` prefix. These represent aggregated spend and token usage across all requests that used that credential.
