SEO Keyword Metrics

Keyword metrics with explicit coverage for every input. Calls are idempotent by user, slug and UUID key. Free owner-only result retrieval: GET /api/skill-api/v1/skills/seo-keyword-metrics/calls/{callId} or nexscope_seo_call_result. Successful results remain available in owner call history. Seven-day source-freshness rules apply only to dependent requests. Missing values are not zero. Examples describe structure only and are not measured results.
