The agent was unable to access Perplexity.ai's own website due to Cloudflare blocking, and instead assembled a comprehensive explanation from third-party sources (Zapier, DigitalOcean, Wikipedia) retrieved via web search. The task was satisfied—the agent provided a coherent, well-structured overview of what Perplexity does, who it's for, pricing, and differentiation—but the site itself was not agent-navigable; all substantive information came from secondary sources, not primary.

• ›Steps [1–2] failed with 403 Cloudflare challenges; the site is actively blocking programmatic access, forcing the agent to rely entirely on search results and third-party documentation.
• ›Steps [8–9] returned full HTML from Zapier and DigitalOcean articles, which became the agent's sole content-bearing sources for pricing details, feature descriptions, and competitive positioning. The agent explicitly cited these in its source list.
• ›The agent filled gaps (e.g., Education Pro pricing, Max tier 'Computer credits', enterprise opacity) by synthesizing information across multiple third-party sources, indicating Perplexity.ai does not publish a machine-readable, agent-friendly primary reference that would allow direct extraction of pricing, features, or positioning.
• ›The site's pricing structure and tier details were not directly accessible; the agent had to infer them from blog comparisons rather than from an official pricing page or API documentation.
