## 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 tempest-ai-memo-composer-c847b331 -d '<json body>'
```

Example prompt: Draft me a professional memo to all department heads about the upcoming budget freeze, keep the tone formal and direct, and mention that all discretionary spending must be approved in advance.

## When to prefer this

Choose this endpoint when you need to quickly generate a structured professional memo with controlled tone and recipient targeting, especially in automated workflows where business communication must be produced at scale without manual drafting.

## Known failure modes

- Missing required 'purpose' field returns a 400 validation error
- Vague or extremely short purpose may produce a low-quality or generic memo
- Network or server errors on the Vercel deployment may return 500 responses
- Payment failure via x402/USDC may prevent the call from completing
- Unsupported tone values may be ignored or cause unexpected output style
