How this service works
Sentiment from -1 to +1 with confidence, mixed-opinion flag and a separate score per aspect you name (price, support, delivery). Abstains when the text is ambiguous.
Output
Returns a sentiment score between -1.0 (most negative) and +1.0 (most positive), a confidence value indicating how certain the model is, a boolean mixed-opinion flag indicating whether the text contains conflicting sentiments, and — when aspects are provided — individual sentiment scores for each named aspect (e.g. price: 0.3, support: -0.6). If the text is ambiguous, the endpoint abstains rather than returning an unreliable score.
Example use cases
E-commerce review aspect scoring
“Analyze this product review and give me sentiment scores for price, quality, and delivery separately: 'Shipping was lightning fast and the build quality is excellent, but honestly I thought it was overpriced for what you get.' Also flag whether the opinion is mixed.”
Support ticket sentiment triage
“Can you score the sentiment of this incoming support ticket and break it out by support and product aspects? The message is: 'Your team was really helpful and friendly, but the software keeps crashing every morning.' I want to know the overall score, confidence, and whether the customer has conflicting feelings.”
Survey response ambiguity detection
“Run sentiment analysis on this survey response and tell me if it's too ambiguous to score confidently: 'It was okay I guess, some parts were good and some weren't really what I expected.' Break down price and experience as separate aspects if you can.”
Technical details
Endpoint
POSThttps://verdict.kechlab.com/v1/sentiment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, multi-dimensional sentiment analysis with explicit confidence signaling and the ability to score named aspects (price, support, delivery) independently. It is especially valuable when you need to know not just polarity but how certain the model is, and when you need to handle ambiguous text gracefully via abstention rather than a forced classification. Prefer this over generic sentiment APIs when aspect-level granularity and mixed-opinion detection matter for your use case.
Side effects
- Text too ambiguous — endpoint abstains and returns no score rather than a low-confidence guess
- Too many aspects provided — schema allows up to 6; exceeding this may be rejected
- Empty or very short text — may trigger abstention or low confidence
- Non-English or mixed-language text — may reduce accuracy or cause abstention
- Malformed aspects array — non-string items or null values may cause a validation error
