The agent successfully assembled a comprehensive overview of Vivo by relying entirely on web search results and external sources, since the official vivo.com.br site returned 403 errors. The site was not directly navigable, forcing the agent to work around access barriers through search-driven discovery.

• ›Direct site access failed completely (403 errors on homepage and subpages), indicating either geo-blocking, authentication requirements, or technical issues — the site did not surface any content to the agent directly.
• ›All substantive facts came from web search results (67% of navigation origin), which returned third-party tourist guides, competitive analyses, and news articles rather than official Vivo pages, suggesting Vivo's own site has poor SEO or content discoverability.
• ›The agent had to infer current 2026 pricing and market share from fragmented external sources; broadband pricing data was explicitly noted as dated (2022), and the agent acknowledged gaps in postpaid plan details and service quality differentiation.
• ›The official Vivo URLs that appeared in search results (vivo.com.br/para-voce, vivo.com.br/para-empresas) were cited in the sources but never successfully fetched, leaving the agent unable to verify or ground claims directly on first-party documentation.
• ›The agent filled structural gaps using model reasoning (e.g., bundling as a differentiator, positioning competitive claims) rather than explicit site content, and was transparent about what it could not find.
