## 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-964d0338 -d '<json body>'
```

Example prompt: Draft a professional memo to all department heads about the new remote work policy rollout, using a formal tone and noting that the changes take effect next quarter.

## When to prefer this

Choose this endpoint when you need to quickly generate a structured internal memo or business communication and want AI-assisted drafting with tone and recipient control. It is ideal for automating routine internal communications at scale or when a human writer is unavailable. Prefer this over a generic LLM prompt when you want a pay-per-call, production-ready endpoint integrated into a USDC payment workflow.

## Known failure modes

- Missing required `purpose` field returns a 400 validation error
- Overly vague or empty purpose may produce generic or low-quality memo output
- Payment failure or insufficient USDC balance prevents the call from completing
- Very long context strings may be truncated or cause latency increases
- Unsupported tone descriptors may fall back to a neutral default tone
