The agent could not access the target domain (api.payroll.justworks.com returned 404s) and instead reconstructed a comprehensive answer about Justworks' payroll and PEO services by assembling information from web search results, comparison guides, and third-party API documentation sites. The site proved largely inaccessible to direct fetches; the agent relied on search-sourced content and prior knowledge to synthesize pricing, positioning, and API details that Justworks does not publish directly at the queried subdomain.

• ›The api.payroll.justworks.com domain itself is non-functional (step [1] → 404), and common documentation paths (/docs, /documentation, /api) also returned 404s, signaling that Justworks does not host public API docs at this subdomain. The actual Partner API is documented elsewhere (public-api.justworks.com), which the agent discovered via search and prior knowledge, not direct navigation.
• ›All actionable content came from web search results (steps [7], [8], [14], [15]) and successfully fetched third-party guides (steps [18], [20]). The agent's own domain fetches uniformly failed; Justworks' corporate site (www.justworks.com) and help center (help.justworks.com) returned 403 Cloudflare challenges, blocking direct crawl access. The agent had to rely on cached/indexed content discovered through search.
• ›The agent synthesized pricing, competitive positioning, and API details from multiple third-party sources (StackFYI, johngalt-finance.com comparison articles, Finch integration docs, API Report Card ratings) rather than primary Justworks documentation. This required significant interpolation and assembly work; no single fetched page contained the full answer. The site is not agent-ready for this discovery task — critical information is either behind access barriers or scattered across external evaluator sites.
