Fetch longtail (low search volume) keywords (v1/keywords/longtail)
AI agents call keywordsLongtail to retrieve information from Seo Data Api without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a query/retrieval operation that accesses SEO keyword data without side effects. It returns informational data about search terms and volumes, which is fundamental Read category behavior. The low severity reflects minimal blast radius—misuse would retrieve unwanted competitive intelligence but cannot modify systems, execute code, or cause financial harm.
From the tool's definition Tool fetches longtail keywords with low search volume; the verb 'fetch' and endpoint structure (v1/keywords/longtail) indicate data retrieval only. No modification, deletion, or execution of external operations.
