## 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-ff8b19c1 -d '<json body>'
```

Example prompt: Can you draft a memo to the entire engineering department about our new code review policy, using a professional tone, and add some context that this is effective starting next quarter?

## When to prefer this

Choose this endpoint when you need to quickly generate a structured, professional business memo with configurable tone and recipient, especially within automated workflows that pay per call using USDC. It is well-suited for agents that need programmatic memo drafting without managing a full LLM pipeline.

## Known failure modes

- Missing required 'purpose' field returns a validation error
- Vague or empty purpose may produce generic or low-quality memo output
- Network or Vercel cold-start latency may cause occasional slow responses
- Payment of 0.3 USDC not completed via x402 results in a 402 Payment Required response
- Overly long context strings may be truncated or cause unexpected output
