The agent assembled a coherent explanation of Castari by working around a nearly-empty main website. The castari.com homepage and all logical subpages (/pricing, /features, /docs) returned 404s or blank content, forcing the agent to rely on the Y Combinator launch post and external documentation to answer what Castari does, who it's for, how it's priced, and how it differs from alternatives. The site itself was not navigable for this discovery task—the agent had to infer Castari's positioning from third-party sources.

• ›Step [10] (Y Combinator launch post) was the primary content source and is explicitly cited; it contained the positioning ('Vercel for AI Agents'), target audiences (internal agents, agent-as-product companies), and differentiation narrative (agent-first layer vs. raw sandbox platforms). This single external post provided the backbone of the answer.
• ›Step [9] (docs.castari.com/) returned a 200 but no accessible content; subsequent attempts to fetch specific doc pages returned 404s, indicating the documentation structure is either not yet built or blocked from public access. The agent could not extract pricing, features, or integration details from official docs.
• ›Steps [3], [4], [5] all returned 404s (/pricing, /features, /docs), confirming the main site has no published information architecture. The homepage [1] itself was fetched but appears to be a marketing shell with no visible text content—the agent never extracted information from it directly.
• ›The agent had to run three web searches [7, 8, 11, 13, 14, 15] to find any structured information about Castari, indicating the site publishes almost nothing under its own domain. Pricing details remain absent even from external sources (agent correctly notes this is 'free in beta, usage-based at launch, rates TBD').
• ›The site is extremely early-stage (Y Combinator S25, ~2025 founding) and appears to gatekeep product details behind authentication; the agent could not explore the running platform. Public discovery of Castari's features, architecture, or pricing requires external lookups rather than site navigation.
