Probe a $address to discover its $402 pricing terms, revenue model, current supply, and any nested $addresses below it. Use this before acquiring content to understand what you
AI agents call path402_discover to retrieve information from Path402 — Tokenised Web Content for AI Agents without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
path402_discover retrieves and queries metadata about tokenised content pricing and structure. The verb 'discover' combined with 'probing' for pricing terms and supply indicates passive information gathering. No side effects, state changes, or external operations are triggered. This is a Read operation despite the somewhat technical context of the $402 protocol.
From the tool's definition Tool description states it 'Probe[s] a $address to discover its $402 pricing terms, revenue model, current supply, and any nested $addresses' — pure discovery and information retrieval with no modification, deletion, or execution of external operations.
