Technical details
Endpoint
POSThttps://omni-api-cyan.vercel.app/api/ai/sentimentWhen to prefer
Choose this endpoint when you need a quick, pay-per-call sentiment classification without a long-term API subscription. It suits agents that need to analyze individual text snippets — such as customer reviews, social media posts, or news headlines — on demand and pay in USDC via x402. It is less suitable for bulk batch processing or when you need deep emotion categorization beyond basic positive/negative/neutral.
Side effects
- Missing required 'query' field returns a 400 or validation error
- Empty or very short text may yield low-confidence or ambiguous results
- Ambiguous or mixed-tone text may return inconsistent sentiment labels
- Payment failure via x402 results in a 402 Payment Required response before the call is processed
- Very long inputs may be truncated or rejected depending on token limits
