Scans a domain’s public robots.txt, llms.txt, sitemap declaration and homepage, and scores it out of 100 across three pillars: discoverability (can AI crawlers reach it), technical foundation (can machines parse it), and content & trust (does it look like a credible source). Returns the score, the three pillar scores, access state for the 10 tracked AI crawlers, every failed check with its fix, and how the score compares to Citehound’s own benchmark data. If the site looks like a store (two or more of five signals), it also reports a separate agentic-commerce sub-score: whether a UCP merchant profile exists at /.well-known/ucp, whether one product page has Product schema with name, price, availability and image, and whether the llms.txt looks like a platform default. That sub-score is never part of the 100. Call this first for any domain. It fetches the live site (a store scan reads up to one extra product page), so avoid calling it in a tight loop for the same domain.
