## 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-1d69cb49 -d '<json body>'
```

Example prompt: Can you do a vibe check on this email draft I wrote? 'Hey team, just a reminder that deadlines are not suggestions and I expect everyone to actually show up prepared this time.' — I want to know what tone it gives off before I hit send.

## When to prefer this

Use this endpoint when you need a quick tone or mood check on a piece of writing before publishing or sending — particularly useful for social media captions, emails, or marketing copy where the emotional register matters. It's part of the Inkbox pay-per-call suite, so it's well-suited for agents that need on-demand tone analysis without a subscription.

## Known failure modes

- Missing required 'text' field returns validation error
- Empty string input may return unhelpful or null result
- Payment failure via x402 blocks the call with 402 status
- Very long text inputs may exceed token limits or time out
- Ambiguous or very short text may produce low-confidence or generic tone labels
