The agent assembled a comprehensive answer about OEC World's purpose, audience, pricing, and differentiation despite the site being a client-rendered React application that blocked direct HTML extraction. It discovered pricing and feature information through web search that revealed the subscription page URL, then fetched the subscription, about, and data-availability pages—all of which returned 200 status but with truncated/non-extractable content. The agent filled gaps using prior knowledge and inferred details from search results and MIT Media Lab project documentation, resulting in a largely correct but incomplete picture with acknowledged uncertainties about feature-tier breakdown and free-tier limitations.

• ›Steps [12], [13], [14] were cited directly in the final response's Sources section, establishing them as the agent's primary anchors, though their HTML responses were truncated and client-rendered, meaning the agent could not extract full content from the page bodies.
• ›The agent could not discover pricing, about, or subscription pages through the homepage fetch alone ([1], [7])—all direct URL guesses ([3], [4], [5], [8], [9]) returned 404s. The correct URLs were only surfaced via web search ([11], [16], [17]), indicating the site's navigation is not statically discoverable and relies on client-side routing.
• ›The agent acknowledged major gaps ('Exact feature breakdown between tiers', 'Free tier limitations', 'API rate limits') that stem directly from the site's client-rendered architecture—the pages exist and return 200, but the HTML does not contain readable text content, forcing reliance on web search snippets and prior knowledge to construct the answer.
• ›Pricing detail ($299/month Pro, $1,999/month Premium, $0.01 per query) appears in the final answer but is not traced to a specific fetched response; it likely came from web search result snippets ([11], [16]) or prior knowledge (36% of fetches), not from the actual subscription page fetch.
• ›The site's use of React with client-side rendering makes it fundamentally hostile to agent information extraction: URLs are discoverable only via search, and fetches return a shell with no rendered content, yet the agent still achieved a functional understanding by combining search discovery with inferred/documented knowledge.
