{"name":"content-authenticity-report","description":"Content authenticity report: send a URL (or raw text) and find out whether a page is AI-generated slop before your agent cites, summarizes, or acts on it. Distinct from content-trust-check (moderation + originality on text you already hold): this starts from a live URL and also reads the page's lead images. Composite: one call runs scrape (required, also sources up to two lead images) then, in parallel, ai-content-detector on the text (required when there is enough text) and ai-image-detector on each lead image (optional, degradable). Raw text input skips extraction and images. Returns a per-text read, a per-image read, and one authenticity_score (0-1, 1 = authentic) blending text 70% and images 30%. Both detectors are calibrated heuristics, not forensic-level. Use it as a content authenticity checker, AI slop filter for web pages, source quality screen, or a pre-citation check.","price":"$0.06","method":"POST","input_schema":{"properties":{"url":{"type":"string","description":"Page to check (http/https).
