The agent assembled a functional overview of Trạm Plus from the homepage and about section but could not complete critical gaps about pricing, partner terms, or company identity because the site either did not publish this information or left pages uninitialized. A web search found competing Vietnamese EV-charging apps but not Trạm Plus itself, forcing the agent to rely on site-claimed differentiation without external verification.

• ›The partner registration page (/dang-ky-tram) showed only a loading message ('Đang khởi tạo'), preventing the agent from discovering eligibility, fees, or approval terms—a major navigability failure for a business-facing feature.
• ›No legal entity, operator name, or founders are published anywhere on the site; only an email, phone, and address are given. The agent had to note this explicitly as missing rather than infer it from model memory.
• ›Homepage statistics (130+ stations, 20+ swap cabinets, 100+ bus routes, 'hundreds of thousands' of users) are unsourced and undated; the agent correctly flagged this uncertainty rather than treating claims as fact.
• ›The site does not list any pricing, subscription model, or partner fees. The agent correctly identified this as absent from the fetched pages rather than guessing.
• ›Web search for 'Trạm Plus app' returned no app by that exact name, only competing apps (Trạm Sạc EV, Trạm EV, Việt EV, EV Map, Trạmsạc.app); the agent noted the comparison is unverified and acknowledged this limitation in the final response.
