## 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-inquiry-endpoint-0373d5a9 -d '<json body>'
```

Example prompt: Use Inkbox to rewrite this product description to be more engaging and persuasive: 'Our coffee maker brews hot coffee quickly and has a large water tank that you don't have to refill often.'

## When to prefer this

Choose this endpoint when you need a pay-per-call, no-subscription AI writing assistant that can handle drafting, rewriting, translating, or optimizing arbitrary text content. It is well-suited for agents that need on-demand content generation billed in USDC micro-payments rather than a monthly SaaS plan. Avoid if you need structured data extraction, image generation, or highly specialized domain writing (legal, medical) with auditability requirements.

## Known failure modes

- Missing required `content` field returns a validation error
- Empty or very short content string may produce low-quality or nonsensical output
- Ambiguous instructions embedded in content may yield unexpected transformations
- Payment failure (insufficient USDC balance) blocks the request before processing
- Rate limiting or service unavailability on the Netlify-hosted endpoint may return 5xx errors
