How this service works
Classify content: topic tags, category, and sentiment with confidence scores.
Output
Returns topic tags, a category label, and optionally a sentiment classification (positive, negative, or neutral), each accompanied by a confidence score indicating the model's certainty.
Example use cases
Automated support ticket routing
“I have a new support ticket that just came in — classify it into one of these categories: 'billing', 'technical', 'account', or 'general', and tell me the sentiment so I know how urgent it is. Here's the text: 'I was charged twice this month and nobody has responded to my emails.'”
Content moderation tag labeling
“Tag this user-submitted forum post with relevant topic tags and assign it a category, and also check if the sentiment is negative so we can flag it for review: 'This product is an absolute scam. Don't waste your money.'”
News article topic categorization
“Classify this news article excerpt into a topic category and pull out the key topic tags — I don't need sentiment for this one. Here's the text: 'The Federal Reserve announced a 0.25% interest rate hike today amid ongoing inflation concerns.'”
Technical details
Endpoint
POSThttps://api.exo-trust.com/execute/classifyWhen to prefer
Choose this endpoint when you need combined topic tagging, category assignment, and optional sentiment analysis in a single call with confidence scores. It is particularly suited for pipelines that need to route, filter, or triage text content — such as support tickets, reviews, or articles — without building a custom classifier. Prefer this over general-purpose LLM prompting when you need structured, scored output that is consistent and cost-predictable at $0.05 per call.
Side effects
- Empty or missing 'text' field causes a validation error
- Text that is too short or ambiguous may return low confidence scores
- Invalid values in the 'categories' array may be ignored or cause errors
- Very long texts may be truncated or rejected depending on token limits
- Non-English text may yield lower accuracy if multilingual support is limited
