Particle Pro – List Company Products

Use this endpoint when you need a structured, hierarchical view of a company's product portfolio rather than a flat list. It is particularly useful for competitive intelligence, investor research, or building product catalogs. Prefer this over general web search when you want structured, machine-readable product data for a specific company, especially when you need nested categories rather than a simple enumeration.

• Company slug, domain, or ID not found — likely returns a 404 or empty result
• Invalid status filter value — may return an error or empty results
• Company exists but has no products catalogued — returns an empty tree
• Rate limiting or payment failure (x402) if the $0.03 USDC fee cannot be processed
• Malformed path parameter — returns a 400 bad request
