How this service works
Classify text into one of your provided labels, with confidence.
Output
Returns the winning label from the caller-supplied list and a numeric confidence score (0–1) indicating how certain the model is about that classification.
Example use cases
Support ticket routing by category
“I have a new support message: 'I can't log in to my account after resetting my password.' Classify it into one of these categories — billing, account-access, technical-bug, or general-inquiry — and give me the confidence score so I know how sure you are.”
Content moderation intent detection
“Classify this user comment as either safe, hate-speech, spam, or misinformation and tell me the confidence: 'Buy cheap followers now — 10k for just $5, guaranteed!'”
Product review sentiment labeling
“Label this product review as positive, negative, or mixed and show me the confidence score: 'The battery life is amazing but the screen cracked after two weeks.'”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/classify-textWhen to prefer
Choose this endpoint when you need fast, zero-shot text classification against a custom set of labels you define at call time — especially useful when categories change per use-case and you don't want to train a model. Prefer it over general-purpose LLM prompting when you need a structured label + confidence score returned in a consistent, machine-readable format at a fixed per-call price.
Side effects
- No labels provided — endpoint requires at least two candidate labels to choose from
- Empty or too-short text input returns a low-confidence or error response
- Ambiguous text where all labels score similarly yields a low confidence score
- Unsupported language text may produce unreliable results
- Rate limits or payment failures (x402) will return 402 or 429 status codes
