The agent assembled a partial description of MercadoLibre by retrieving the investor relations site (which provided business structure, user counts, and geographic scope) and conducting a web search that surfaced third-party fee comparisons and competitor analyses. The homepage and developer portal were both inaccessible (403 errors), forcing reliance on external sources for pricing and competitor positioning, which the agent explicitly flagged as unverified.

• ›Step [2] (investor.mercadolibre.com) was the only official company source accessible and provided core business segment descriptions, user metrics (88M MAU, 9M SMEs), and geographic names, but did not explain revenue model or logistics details.
• ›The agent guessed the investor subdomain URL from memory rather than discovering it through site navigation—no internal links or redirects from the main domain led there.
• ›Step [5] (web search) returned third-party fee calculators and comparison blogs as its only content-bearing results; no official MercadoLibre fee schedule was accessible or returned by search, so all pricing claims are explicitly marked unverified.
• ›The homepage (step [0]) and developer portal (step [3]) both returned 403 Forbidden, blocking access to the most direct sources for marketplace description, official fees, and API documentation.
• ›The agent acknowledged key ambiguities (e.g., whether 88M users covers the whole company or only Mercado Pago, undefined logistics business) as gaps in the investor page rather than attempting to infer them from external sources, showing appropriate epistemic caution.
