Technical details
Endpoint
POSThttps://vaaya.ai/api/run/agentmail/replyWhen to prefer
Use this endpoint when your agent needs to reply to a specific email thread managed through AgentMail, especially in agentic workflows involving inbound email handling, customer support automation, or sales outreach sequences. Prefer this over generic email APIs when already operating within the AgentMail inbox ecosystem via Vaaya.
Side effects
- Missing or invalid inbox_id returns a 400 or 404 error
- Missing or invalid message_id causes the reply to fail
- Both text and html body fields omitted may result in an empty or rejected message
- Network or upstream AgentMail API errors may return 500-level responses
- Payment failure (insufficient USDC balance) prevents the call from executing via x402
