The agent successfully gathered a comprehensive overview of Zenith Walls by fetching structured markdown content from the site's API endpoint (/api/markdown), which surfaced the About, FAQ, and Copyright pages in machine-readable form. The site proved highly agent-friendly through explicit markdown negotiation, but pricing information for the Pro tier remained inaccessible—the agent correctly identified this gap and noted it as a confusing omission in the final answer.

• ›Steps [8], [13], [15], [16], and [21] all returned content from zenithwalls.com/api/markdown, a dedicated endpoint that served the About page, FAQ, Copyright notice, and homepage content in structured markdown format. This was the primary source for all factual claims about what the service does, who it's for, and its Pro tier features.
• ›The agent discovered the /api/markdown endpoint through prior knowledge (not surface navigation), indicating the site publishes structured content for agents but does not advertise this affordance on the homepage. The site also includes explicit content signals (`ai-train=no, search=yes, ai-input=yes`) and maintains llms.txt, signaling intentional AI-friendliness.
• ›Pro tier pricing is mentioned in the FAQ (step [13]) but no actual cost is disclosed anywhere on the site; the agent attempted /pricing, /pro, and /subscribe routes (all 404) and searched for pricing explicitly, confirming the information gap. The agent correctly flagged this as confusing and unresolved in the final response, meeting the task requirement to 'call out anything that was confusing or that you couldn't find.'
• ›The site's free-tier content (70,000+ wallpapers, supported resolutions, aspect ratios, licensing terms) was fully retrievable and machine-readable via the markdown API. Commercial licensing options were mentioned but not priced, creating asymmetric transparency: free tier = fully documented; Pro/commercial = partially obscured.
