The agent successfully assembled a comprehensive overview of OceanBase despite the official website being inaccessible due to rate limiting. It worked around the barrier by retrieving information from Alibaba Cloud documentation (steps 9, 10, 13) and GitHub (step 16), which provided the technical architecture, use cases, pricing models, and competitive differentiation needed to explain the product to a third party. The site itself was not navigable, forcing the agent to rely on web search and external documentation.

• ›The official en.oceanbase.com domain returned 429 rate-limit errors on all direct fetch attempts (steps 1, 6, 7), making the site completely inaccessible. The agent had to pivot to alternative authoritative sources: Alibaba Cloud's official documentation and GitHub repository.
• ›Step 9 (Alibaba Cloud 'What is OceanBase') provided the foundational definition and technical architecture (Paxos replication, MemTable/SSTable, HTAP capability, MySQL/Oracle compatibility). Steps 10 and 13 returned billing model information (subscription vs. pay-as-you-go, marketplace transition) but did not expose specific pricing—the final response correctly flagged this as missing.
• ›Step 16 (GitHub repository) confirmed the open-source availability and community edition existence but provided no detailed feature comparisons or use-case documentation. The agent had to infer competitive positioning from web search results (steps 18) rather than from the site's own comparison pages.
• ›The site does not publish transparent pricing, customer case studies (beyond Alipay/Taobao), or clear positioning for when to use open-source vs. cloud editions. The agent noted this gap explicitly, demonstrating awareness of what the site failed to surface.
• ›The final response cited 8 URLs as sources, but only 4 were fetched as tool calls (steps 9, 10, 13, 16). The other 4 sources (steps 3, 14, 15, 17, 18) were web search results that provided routing or fragment confirmation rather than full-page content, yet the agent did not extract or cite specific text from those searches—they served as discovery pointers only.
