Example use cases
Professional business email auto-reply
“I just got this email from a client asking about project timelines — can you write a professional reply that says we're on track and will deliver by end of month? Here's the original: 'Hi, can you give us an update on the project status and expected delivery date?'”
Polite decline to a meeting request
“Draft me a polite but firm reply declining this meeting request: 'Would you be available for a 1-hour call this Thursday to discuss a potential partnership?' — I'm too busy this week but open to reconnecting next month.”
Customer support email response
“Write a helpful customer support reply to this complaint email: 'I ordered 3 weeks ago and still haven't received my package, this is unacceptable.' — keep the tone apologetic and offer to investigate the issue.”
Technical details
Endpoint
POSThttps://nexus-api-virid.vercel.app/api/ai/email/replyWhen to prefer
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.
Side effects
- 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
