The agent was unable to access parispass.com directly due to Cloudflare protection but successfully assembled a comprehensive explanation of the Paris Pass by synthesizing web search results and third-party reviews from multiple reliable sources. The site itself is not machine-readable to the agent, forcing reliance on external intermediaries (review sites, Go City's corporate site, travel guides) to answer discovery and evaluation questions about pricing, inclusions, and differentiation.

• ›The official parispass.com domain returns 403 Cloudflare blocks on all attempted fetches [1, 4, 5], rendering the primary source completely inaccessible; the agent pivoted entirely to web search and prior knowledge.
• ›Search queries [3, 7, 8, 9, 12] returned links to parispass.com pages in snippets but those pages were themselves inaccessible; the agent instead fetched and cited third-party review sites (The Savvy Backpacker [10], travel comparison guides, Trustpilot reviews) that had already synthesized the official messaging.
• ›The agent's final answer cites 8 sources, but only 1 was directly fetched and returned 200 status [10]; the remaining 7 were inferred from search snippets, prior knowledge, or were parispass.com/gocity.com URLs the agent could not actually read—this represents heavy reconstruction rather than direct reading.
• ›Site navigation structure is opaque to the agent; URL patterns like 'parispass.com/en/how-it-works' and 'parispass.com/en/passes' appear in search results but cannot be visited, so the agent cannot verify whether key information (pricing tiers, inclusion rules, booking inconsistencies) is clearly presented on the official site or only surfaced through third-party commentary.
• ›The agent correctly identified confusing aspects (e.g., 2–3 day passes exclude Museum Pass while 6-day includes it; booking methods vary by attraction) but these were sourced from review sites and user complaints [10, 12] rather than from official documentation, suggesting the official site may not clearly explain these distinctions.
• ›The Go City relationship is central to the product but was not obvious from the primary domain; the agent discovered it through search and prior knowledge, not from navigating parispass.com itself.
