How this service works
Sentiment analysis: classify text as positive, negative, or neutral with a confidence score and an alternate label. Powered by Jev, with an automatic Groq-hosted LLM fallback if Jev is slow or unavailable ("engine":"jev"|"fallback" in the response) - under 4.5s guaranteed. Try GET /sentiment/sample.
Output
Returns a sentiment label (positive, negative, or neutral), a confidence score, an alternate label, and an engine field indicating whether the classification was done by Jev or the Groq-hosted LLM fallback. Response is guaranteed within 4.5 seconds.
Example use cases
Customer review tone detection
“Classify this product review as positive, negative, or neutral and give me a confidence score: 'Battery life is excellent but the screen is disappointingly dim.'”
Social media comment moderation
“Tell me whether this tweet is positive, negative, or neutral: 'Can't believe how bad the support experience was — waited 3 hours and got no resolution.'”
Support ticket prioritization
“Analyze the sentiment of this support message and tell me how confident you are in the classification: 'I've been trying to reach someone for days and nothing works, I'm incredibly frustrated.'”
Technical details
Endpoint
GEThttps://x402.agentindex.world/sentiment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, reliable sentiment classification with a confidence score and a guaranteed sub-4.5s response time. The automatic fallback to a Groq-hosted LLM makes it more resilient than single-provider alternatives. Ideal for real-time pipelines where uptime and speed matter more than fine-grained emotion categories.
Side effects
- Text exceeds 4000 character limit — request rejected
- Both Jev and Groq fallback unavailable — timeout or error response
- Empty or missing text field — validation error
- Network issues causing latency to exceed the 4.5s SLA
