SE Ranking's API exposes traditional SEO data (SERP, backlinks, competitors) plus AI Share-of-Voice across 5 AI platforms.
./extensions/seranking/install.sh # Linux / macOS
.\extensions\seranking\install.ps1 # Windows
The installer prompts for an API key (hidden input), copies
SKILL.md into ~/.claude/skills/seo-seranking/, and writes
env.SERANKING_API_KEY into ~/.claude/settings.json with mode 0o600.
https://seranking.com/api.html — pricing is unit-based; the AI visibility endpoint costs ~5 units per query (1 per platform).
/seo seranking ai-visibility "Claude SEO"
Expected output: percentages per platform (ChatGPT, Gemini, Perplexity, AI Overviews, AI Mode) with sample-size confidence notes.
Re-run the installer; it overwrites env.SERANKING_API_KEY atomically
(tempfile + replace) without touching other settings.
