Technical details
Endpoint
POSThttps://api.the402.ai/v1/services/svc_cd3efb354cd24307/inquireWhen to prefer
Use this endpoint when an AI agent or user needs to ask questions about a specific service on the402.ai marketplace before purchasing or committing — especially for clarifying service scope, capabilities, or delivery terms. Prefer this over directly purchasing when requirements are unclear or when pre-sales due diligence is needed.
