The agent successfully assembled a comprehensive explanation of Polymarket by combining information from official help center and documentation pages, supplemented by web search context on alternatives. The site's documentation was well-structured and accessible once discovered via search, but the main domain (polymarket.com/) itself did not surface core educational content—the agent had to route through help.polymarket.com and docs.polymarket.com to find what Polymarket is, how it works, and its fee structure. The main site appears optimized for trading, not self-service discovery.

• ›Step [6] (help.polymarket.com/what-is-polymarket) and step [8] (help center on prediction markets) provided the foundational 'what is' and 'how it works' content. Step [10] and [12] provided detailed fee structures across market categories. These were the content backbone of the answer.
• ›The agent could not fetch polymarket.com/about (404) or polymarket.com/help (404), indicating the main site does not host educational content—it forced discovery via help.polymarket.com and docs.polymarket.com subdomains, which were not linked from or discoverable on the homepage fetch [0]. The agent had to use web search [5] to find these resources.
• ›Fee information was well-documented (tiered by market category, maker vs. taker, percentage ranges), but regulatory/legal status, dispute resolution, liquidity mechanics on thin markets, geographic restrictions, and market creation processes were either absent or buried—the agent correctly flagged these as confusing gaps not present in fetched content.
• ›The site's main domain is agent-unfriendly for discovery; it returned homepage HTML [0] with no clear navigation or metadata to signal the existence of help/docs subdomains. The agent had to rely on prior knowledge of documentation-site patterns and web search fallback.
• ›The agent assembled content from multiple fragments (what is a prediction market + what is Polymarket + fees + competitor comparisons) rather than finding a single unified explanation, suggesting the site lacks a cohesive 'onboarding' or 'overview' page accessible from the homepage.
