Returns analysis results for a vault. Free-tier teams receive summary-only results; paid teams receive full facet data and AI insights. Analysis is async; if status is 'processing', poll with exponential backoff (5s, 10s, 20s, 40s, max 60s). Analysis can be as quick as 20-30 minutes for under 500,000 lines of code. Larger codebases can take much longer, especially with the security scan. Facet meanings are documented in resources://docs/facets; AI Quotient is a code-quality metric (not AI-generated code). AI insights can take a few minutes after analysis completes; if ai_insights is empty, poll again and check ai_insights_status per facet (ready/processing/not_available). This endpoint always returns the latest version only; once reanalysis starts, prior versions are no longer accessible here. Requires X-API-Key (existing users can generate an API key in the web app). If headers aren't supported, pass api_key in arguments.
