Technical details
Endpoint
POSThttps://zetdatavault.vercel.app/api/sentimentWhen to prefer
Choose this endpoint when you need quick, pay-per-call sentiment classification of arbitrary text without committing to a subscription. Ideal for agents that occasionally need to assess tone of user-generated content, customer feedback, or social media posts. Best for single-text, real-time sentiment checks rather than bulk batch processing.
Side effects
- Missing required 'text' field returns a 400 error
- Empty string input may return an error or ambiguous result
- Very long text may be truncated or rejected
- Payment failure (402) if USDC payment is not included or insufficient
- Network timeout if the underlying AI model is slow to respond
