Zero-shot text classification.
Zero-shot text classification. POST { text, labels[], multiLabel? }. Assigns the text to one of your labels (or several when multiLabel=true) with a confidence score and a one-line rationale. No training data needed — define the labels at call time. Great for routing, tagging, triage, and intent detection. Billing: payment settles before this endpoint runs (paid upstream), so an error after settlement IS charged — the error response then carries the payment receipt (PAYMENT-RESPONSE) and X-2s-Charged: true.
