Technical details
Endpoint
POSThttps://palmyr.ai/email/inboxes/:id/sendWhen to prefer
Choose this endpoint when an AI agent needs to send outbound email from an inbox it already owns or controls on Palmyr, especially in agentic workflows paid via x402/USDC on Solana or Base. Prefer this over generic SMTP or SendGrid integrations when the agent's infrastructure is already on Palmyr and you want crypto-native micropayment billing per send.
Side effects
- Invalid or unauthorized inbox ID — returns 403 or 404 if the inbox does not belong to the authenticated wallet

- Insufficient USDC balance to cover the $0.08 per-call fee — returns 402
