The agent worked around an inaccessible website by relying entirely on web search results and prior knowledge to answer the task. Europcar.fr itself is a JavaScript-heavy single-page application that returned 404s on direct URL guesses for key pages, forcing the agent to assemble its understanding from third-party comparison sites and general search results rather than primary sources on the French domain.

• ›Steps [1], [3], and [4] fetched from europcar.fr directly but returned either truncated HTML (homepage) or 404s (internal pages), confirming the site is client-side rendered and not crawlable via direct URL routing.
• ›All substantive content in the final answer came from web search results [6], [8], [10] and prior knowledge—not from the target domain. The agent cited third-party sources (KAYAK, comparison review sites) rather than Europcar's own pages, and used pricing data from secondary sites like KAYAK rather than europcar.fr.
• ›The agent could not access Europcar.fr's own pricing policies, insurance details, loyalty programs, booking flow, or regional pricing variations. It noted these gaps explicitly, indicating what was missing rather than hallucinating details.
• ›The site's JavaScript-first architecture and client-side routing made it effectively non-machine-readable; the agent had to rely on external aggregators and general knowledge to reconstruct the company's positioning, pricing tiers, and competitive differentiation.
