How this service works
Draft, rewrite, translate, and optimize written content. 25 AI-powered endpoints. Pay-per-call with USDC on Base.
Output
Returns a JSON object with a success boolean and a data object containing the vibe/tone assessment of the submitted text, likely including mood classification, tone descriptors, and qualitative feedback on the writing's emotional register.
Example use cases
Social media post emotional resonance check
“I just wrote a caption for my Instagram post about our new product launch. Can you tell me what vibe it gives off and whether it feels authentic or too salesy? Here's what I wrote: 'We spent two years building this. We hope you love it as much as we do.'”
Customer service email tone assessment
“I'm responding to an upset customer and I want to make sure my reply sounds genuinely apologetic and helpful, not defensive. Can you analyze the tone of this draft and let me know if it comes across as caring or if it feels too formal and robotic?”
Marketing headline energy evaluation
“I've got three headline options for our campaign and I need to know which one feels most compelling and energetic without being cringey. Can you vibe-check all three and tell me which one has the best emotional impact?”
Technical details
Endpoint
POSThttps://pen-inkbox402.netlify.app/api/vibe-checkWhen to prefer
Use this endpoint when you need a quick AI-powered assessment of the emotional tone or 'vibe' of a piece of text — particularly useful before publishing marketing copy, social media posts, or customer-facing communications where tone matters. Prefer this over general sentiment analysis when you want nuanced qualitative feedback beyond positive/negative/neutral.
Side effects
- Missing required 'text' field returns validation error
- Empty string input may return error or low-confidence result
- Very short text snippets may produce unreliable vibe assessments
- Payment failure (402) if USDC balance is insufficient
- Rate limiting if too many calls made in succession
- Network timeout on Netlify edge function
