The agent could not access Brex's own website (blocked by Vercel security challenges on steps 1–4) and instead assembled a comprehensive answer entirely from web search results and third-party sources. The final response is well-structured and answers all four questions (what, who, pricing, differentiation), but it is built from external sources rather than Brex's own published materials, making it dependent on second-hand interpretation and potentially out-of-date third-party analyses.

• ›All seven content-bearing steps were web search results (steps 6–8, 11–14) or third-party articles fetched via those search results. None came from brex.com directly; the homepage and key landing pages (/pricing, /product) returned 429 security challenges.
• ›The agent had to rely on 60% prior knowledge and 40% web search to reconstruct Brex's positioning, pricing model, and differentiation. Pricing information was fragmented across multiple third-party review sites (Vendr, Capterra, Nav, CurateSuite) with slightly inconsistent details (e.g., 'free Essentials' tier, then '$12/user/month Premium'), requiring reconciliation.
• ›The agent correctly identified several gaps in the third-party materials—opaque enterprise pricing, unclear card vs. software subscription relationship, unclear Essentials tier limitations—showing awareness that the sources themselves were incomplete, not just the site's transparency.
• ›Brex's own website is not agent-navigable. The Vercel security layer blocks automated access entirely, forcing reliance on indirect sources. This is a critical identity and discovery layer failure: the primary source of truth is unreachable.
