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.com over 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: GET /v1/organizations/cost_report
