Tempest AI Content Engine — Group Classification

Choose this endpoint when you need to classify text against a custom, user-defined set of categories rather than a fixed taxonomy. It is ideal for routing, labeling, and sorting workflows where the category list changes per use case. Prefer this over dedicated sentiment-only or topic-only classifiers when flexibility in category definitions is required. Best suited for pay-per-call usage patterns where you do not want to manage a hosted ML model.

• Missing required `text` field returns an error or empty result
• Ambiguous categories may cause misclassification or low-confidence output
• Very short or context-free text may yield unpredictable category assignments
• Exceeding token limits for long texts may cause truncation or failure
• Payment not included or insufficient USDC balance triggers x402 payment-required error
