A CLI for querying Anthropic Admin API usage and cost data. Requires an Admin API key (`sk-ant-admin...`) from Claude Console → Settings → Admin Keys. Credentials are stored in macOS Keychain.

## Installation

Requires Node.js >= 18 and macOS. The package is open source: https://github.com/cyberash-dev/claude-usage-cli

```bash
npm install -g claude-usage-cli
```

Install from source (if you prefer to audit the code before running):
```bash
git clone https://github.com/cyberash-dev/claude-usage-cli.git
cd claude-usage-cli
npm install && npm run build && npm link
```

After installation the `claude-usage` command is available globally.

## Quick Start

```bash
claude-usage config set-key     # Interactive prompt: enter Admin API key (masked)
claude-usage usage              # Token usage for the last 7 days
claude-usage cost               # Cost breakdown for the last 7 days
claude-usage cost --sum         # Total spend for the last 7 days
```

## API Key Management

Store API key (interactive masked prompt, validates `sk-ant-admin` prefix):
```bash
claude-usage config set-key
```

Show stored key (masked):
```bash
claude-usage config show
```

Remove key from Keychain:
```bash
claude-usage config remove-key
```

## Usage Reports

```bash
claude-usage usage                                    # Last 7 days, daily, grouped by model
claude-usage usage --period 30d                       # Last 30 days
claude-usage usage --from 2026-01-01 --to 2026-01-31 # Custom date range
claude-usage usage --model claude-sonnet-4            # Filter by model
claude-usage usage --api-keys apikey_01Rj,apikey_02Xz # Filter by API key IDs
claude-usage usage --group-by model,api_key_id        # Group by multiple dimensions
claude-usage usage --bucket 1h                        # Hourly granularity (1d, 1h, 1m)
```

JSON output (for scripting):
```bash
claude-usage usage --json
claude-usage usage --period 30d --json
```

Output columns: Date, Model, Input Tokens, Cached Tokens, Output Tokens, Web Searches.

## Cost Reports

```bash
claude-usage cost                                           # Last 7 days, grouped by description
claude-usage cost --period 30d                              # Last 30 days
claude-usage cost --from 2026-01-01 --to 2026-01-31        # Custom date range
claude-usage cost --group-by workspace_id,description       # Group by workspace and description
claude-usage cost --sum                                     # Total cost only
```

JSON output (for scripting):
```bash
claude-usage cost --json
claude-usage cost --sum --json
```

Output columns: Date, Description, Model, Amount (USD), Token Type, Tier.

## 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`
