> ## Agent Instructions
> Cerebrium's documentation MCP server is available at https://cerebrium.ai/docs/mcp for searching and querying these docs directly. Install the Cerebrium agent skill with `npx skills add https://cerebrium.ai/docs`. Append .md to any docs page URL to fetch that page as plain Markdown. API keys and authentication tokens are created in the Cerebrium dashboard at https://dashboard.cerebrium.ai.

# Delete API Key

> Delete an API key and permanently deny its token. Inference requests using the key start failing within a few seconds. This cannot be undone: the key is not recoverable and the token stays denied. The caller must be an owner on the project. Service account keys are rejected here — delete the service account instead.

        Service Account Token authentication. To authenticate API requests:


        1. **Create a Service Account Token:**
           - Go to the [Cerebrium Dashboard](https://dashboard.cerebrium.ai/) and open the **API Keys** page
           - Click **Create Service Account**, name it (e.g., "GitHub Actions CI/CD"), choose an expiry date, and click **Create**
           - **Copy the token** generated for the desired service account

        2. **Use the Token:**
           Include the service account token in the Authorization header of API requests:
           `Authorization: Bearer <your-service-account-token>`

        3. **Best Practices:**
           - Create separate service accounts for different environments (dev, staging, prod)
           - Store tokens securely as secrets in consuming applications or workflows
           - Set appropriate expiry dates and rotate tokens regularly
           - Never commit tokens to source control

        For CI/CD integration examples, see the [CI/CD
        documentation](https://docs.cerebrium.ai/cerebrium/deployments/ci-cd).
