Use this endpoint when an agent or user needs to ask questions about a specific the402.ai marketplace service before committing to purchase, or when human-in-the-loop clarification is needed about service scope, delivery, or pricing. Prefer this over the quote endpoint when the question is open-ended rather than price-specific.
