Security and Data Storage
- Admin API key: stored exclusively in macOS Keychain (service:
claude-usage-cli). Never written to disk in plaintext. - No config files: all settings are passed via CLI flags. Nothing is stored on disk besides the Keychain entry.
- Network: the API key is only sent to
api.anthropic.comover HTTPS. No other outbound connections are made. - Scope: the Admin API key grants read-only access to organization usage and cost data. It cannot modify billing, create API keys, or access conversation content.
- No caching: query results are not cached or persisted to disk.
API Reference
This CLI wraps the Anthropic Admin API:
- Usage:
GET /v1/organizations/usage_report/messages - Cost:
