The agent successfully assembled a comprehensive explanation of Cardmarket by working around a 403 block on the main domain. It relied entirely on web search results and third-party content (Trustpilot, blogs, fee comparison sites, help docs) to answer the task, since direct access to cardmarket.com failed.

• ›Direct access to cardmarket.com was blocked (403 Forbidden) at both the root and /en paths, forcing the agent to rely entirely on external sources rather than primary site content.
• ›67% of navigation originated from web search results, which returned relevant third-party and help-doc URLs but no direct cardmarket.com pages. The agent successfully used search snippets and fetched external pages to piece together the answer.
• ›The agent correctly identified and cited all external sources (Trustpilot, fee comparison sites, culture-of-gaming blog, bluecore.cards) in its final response, maintaining transparency about source layering.
• ›Third-party blogs and help documentation (fetched from external domains) provided the most detailed operational information: buying mechanics (Want List optimization), selling workflow (CSV bulk upload, MKM Pro tier), and Trustee Service protection details — none of which appeared in search snippets alone.
• ›The agent explicitly flagged gaps it encountered: support responsiveness inconsistency, opaque ID verification requirements, and unclear international shipment guarantees — all observations drawn from Trustpilot reviews and blog posts rather than site documentation.
