## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability inkbox-ai-content-studio-vibe-check-70d6abce -d '<json body>'
```

Example prompt: Can you vibe check this caption I wrote for our product launch: 'We're flipping the script on boring software — your workflow just got a serious upgrade'? I want to know if it reads as energetic and bold or if it falls flat.

## When to prefer this

Choose this endpoint when you specifically need a quick AI-powered tone and vibe evaluation of a short-to-medium piece of text — for example, before publishing marketing copy, sending a sensitive email, or finalizing a social media post. It is part of the Inkbox AI Content Studio suite, so pair it with sibling endpoints for drafting or rewriting when you want an end-to-end content workflow. Prefer this over general sentiment analysis when you want richer qualitative tone characterization rather than a simple positive/negative label.

## Known failure modes

- Missing required 'text' field returns a validation error
- Empty string input may return a null or undefined vibe result
- Very short input (single word) may produce low-confidence or generic output
- Network or server errors from the Netlify-hosted endpoint may return 5xx responses
- Payment failure via x402 protocol will block the request before processing
