The official Data Legion CLI lets you enrich and search person and company data directly from the terminal. It’s fully async, outputs JSON to stdout (logs to stderr), and works as both a human-friendly tool and an AI agent backend. AI coding agents like Claude Code, Cursor, OpenClaw, Cline, and Aider can call it directly as a shell tool.

​
Installation

brew install datalegion-ai/tap/datalegion-cli
Requires Python 3.11+.

​
Authentication

Set your API key using the built-in encrypted config store or an environment variable. 
datalegion-cli config set api_key legion_your_key_here

​
Person

​
Enrichment

Look up a person by email, phone, social URL, name, or other identifiers.

# By first/last name with location context
datalegion-cli person enrich --first-name Jane --last-name Doe \
  --company Acme --city "San Francisco" --state california

# Return multiple matches with confidence scores
datalegion-cli person enrich --name "Jane Doe" --company Acme \
  --multiple --min-confidence high --limit 5

# Return specific fields only
datalegion-cli person enrich --email jane@example.com \

​
Utilities

Utility commands are free and don’t consume credits.

​
Clean Fields

Normalize emails, phones, names, domains, and other fields. Pass a JSON payload as a positional argument or via stdin. 
# Positional JSON argument
datalegion-cli utility clean \
  '{"email": "  JANE.DOE+work@GMAIL.COM  ", "phone": "(555) 123-4567", "domain": "https://www.Google.com/about"}'

# From stdin
echo '{"email": "test@GMAIL.COM"}' | datalegion-cli utility clean --stdin
FlagDescription
--stdinRead JSON fields from stdin
--regionDefault phone region (default: US)

​
Hash Email

Generate privacy-preserving email hashes (SHA-256, SHA-1, MD5). The email is a positional argument. 
datalegion-cli utility hash jane@example.com

​
Validate

Check data format and get cleaning suggestions before enrichment. 
datalegion-cli utility validate \
  --email "not-an-email" --phone "+15551234567" --domain "google.com"
FlagDescription
--emailEmail to validate
--phonePhone to validate
--nameName to validate
--domainDomain to validate

​
Agent Integration

The CLI is designed for AI agent workflows. Claude Code, Cursor, OpenClaw, Cline, Aider, and other AI coding agents can invoke it as a shell tool — no MCP configuration needed. All structured output goes to stdout as JSON, while logs and progress indicators go to stderr, so agents and scripts can parse results directly. 
# Pipe to jq
datalegion-cli person enrich --email jane@example.com | jq '.full_name'

# Pipe from stdin
echo '{"email": "jane@example.com"}' | datalegion-cli person enrich --stdin

# Quiet mode (suppress all non-JSON output)
datalegion-cli person enrich --email jane@example.com --quiet
The CLI and MCP server are complementary. Use MCP for native tool-call integration with AI assistants. Use the CLI when you need shell access, scripting, or want a zero-config option that any agent can call via bash.

​
Global Flags

FlagDescription
--verbose / -vEnable debug logging
--quiet / -qSuppress all log output
--helpDisplay command help

​
Auto-Update

The CLI monitors GitHub releases and can self-update. 
# Check for updates
datalegion-cli update --check

# Install updates
datalegion-cli update

# Show current version
datalegion-cli version

​
Credits

CLI commands consume credits at the same rate as the corresponding REST API endpoints. Utility commands are free.

​
Rate Limits

The same rate limits apply to CLI requests as to direct API calls.
