Choose this endpoint when you need fast, low-cost per-call sentiment classification on individual text snippets without managing your own NLP infrastructure. Ideal for agents processing customer feedback, social media posts, support tickets, or any short text where emotional tone is needed. Best when integrated into a micro-payment-friendly workflow using USDC via MPP/Tempo.
