## 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 x402-server-sandy-vercel-app-fc3ed8d2 -d '<json body>'
```

Example prompt: Write me a collector-voiced email newsletter issue about this NFT — I'll pass you the metadata and research analysis — and give me a punchy subject line, preview text, and a full markdown body I can send to my list.

## When to prefer this

Choose this endpoint when you need a fully email-optimized newsletter issue — complete with subject line and preview text — written specifically from a collector's point of view. Prefer this over the Paragraph.xyz article endpoint when you need email-format output rather than a long-form web article, and over the Twitter/Farcaster endpoint when the target channel is email rather than social media.

## Known failure modes

- Missing or malformed NFT metadata object returns a validation error
- Missing research analysis may produce thin or generic content
- Invalid tone config value may be ignored or cause a 400 error
- Payment failure via x402 protocol returns 402 Payment Required
- Overly sparse NFT metadata results in low-quality generic output
