## 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 nexusapi-ai-email-reply-generator-02b15f82 -d '<json body>'
```

Example prompt: Can you draft a professional reply to this email I received: 'Hi, we're interested in your consulting services. Could you send us your rates and availability for next month?'

## When to prefer this

Choose this endpoint when you need a quick AI-drafted reply to an existing email and want to pay per call without managing API keys. Best suited for agents automating email triage, customer support workflows, or personal productivity tasks where a single-shot reply draft is sufficient. Prefer alternatives if you need multi-turn conversation context, email sending capability, or guaranteed formatting like HTML email bodies.

## Known failure modes

- Empty or vague query may produce generic or off-topic reply text
- Missing context about the original email may result in a poorly tailored draft
- Overly long input may be truncated or cause degraded response quality
- Payment failure (HTTP 402) if USDC balance is insufficient
- Service unavailability returning 5xx errors from the Vercel deployment
