Dfseo

dfseo-cli — SEO Data from Your Terminal

A CLI tool wrapping DataForSEO APIs. 43+ commands for SERP analysis, keyword research, site audits, and backlink analysis. All output is JSON by default (machine-readable). Add --output table for human-readable format.

Authentication

Requires DataForSEO API credentials. Set them as environment variables:

export DATAFORSEO_LOGIN="your@email.com"
export DATAFORSEO_PASSWORD="your_api_password"

Or run dfseo auth setup for interactive configuration (saves to ~/.config/dfseo/config.toml).

Verify with: dfseo auth status

Output Conventions

• Default output: JSON on stdout — always parseable, no decorative text
• Errors and progress: stderr — never mixed with results
• --output table — human-readable formatted tables
• --output csv — for spreadsheets and data pipelines
• -q / --quiet — suppress everything except the result
• --dry-run — show estimated cost without executing

Exit codes: 0 = success, 1 = error, 2 = auth failed, 3 = rate limited, 4 = bad params, 5 = insufficient funds.
