## 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 brand-voice-review-4861397b -d '<json body>'
```

Example prompt: Can you review this blog post draft against our brand guidelines — we want a formal but approachable tone, no passive voice, and consistent use of 'customers' not 'users' — and give me a compliance score plus rewritten examples for any sections that miss the mark?

## When to prefer this

Choose this endpoint when you need a per-call, no-account AI review of blog content against brand voice guidelines with a compliance score and concrete rewrites — especially useful for content pipelines, editorial QA automation, or one-off freelance content reviews where setting up a full content management integration is overkill.

## Known failure modes

- Missing or vague prompt causes generic or unhelpful analysis
- Very long blog posts may be truncated or produce incomplete coverage
- Ambiguous brand guidelines in the prompt lead to subjective or inconsistent scoring
- Payment failure via x402 results in no response
- Overly brief input without brand context returns low-value generic feedback
